  • Refereed, Molecular Nutrition and Food Research, Wiley-VCH Verlag, A Phytol-Enriched Diet Activates PPAR-α in the Liver and Brown Adipose Tissue to Ameliorate Obesity-Induced Metabolic Abnormalities, Ji-Yeong An; Huei-Fen Jheng; Hiroyuki Nagai; Kohei Sanada; Haruya Takahashi; Mari Iwase; Natsumi Watanabe; Young-Il Kim; Aki Teraminami; Nobuyuki Takahashi; Rieko Nakata; Hiroyasu Inoue; Shigeto Seno; Hideo Mastuda; Teruo Kawada; Tsuyoshi Goto, Scope: Peroxisome proliferator-activated receptor alpha (PPAR-α) is a ligand-activated transcription factor that regulates lipid and carbohydrate metabolism. We investigate the effects of naturally occurring PPAR-α agonists, phytol, and its metabolite phytanic acid, on obesity-induced metabolic disorders using a mouse model. Methods and results: A luciferase reporter assay shows that phytanic acid potently activates PPAR-α among PPAR subtypes. In high-fat-diet-induced, severely obese mice, a phytol-enriched diet increases phytanic acid levels in the liver and adipose tissue, where PPAR-α is abundantly expressed. A phytol-enriched diet ameliorates severe obesity and the related metabolic abnormalities of white adipose tissue. Moreover, the expression of PPAR-α target genes in the liver and brown adipose tissue is enhanced by a phytol-enriched diet, suggesting that phytol and phytanic acid activate PPAR-α in these organs. We confirm that phytanic acid treatment induced PPAR-α target gene expression in both primary hepatocytes and brown adipocytes from wild-type mice, but not in these cells from PPAR-α-deficient mice. Conclusion: A phytol-enriched diet may increase phytanic acid levels in the liver and brown adipocytes, thereby activating PPAR-α in these organs and ameliorating obesity-induced metabolic diseases., 01 Mar. 2018, 62, 6, e1700688, Scientific journal

  • Refereed, JOURNAL OF AGRICULTURAL AND FOOD CHEMISTRY, AMER CHEMICAL SOC, Rice Koji Extract Enhances Lipid Metabolism through Proliferator-Activated Receptor Alpha (PPAR alpha) Activation in Mouse Liver, Haruya Takahashi; Hsin-Yi Chi; Shinsuke Mohri; Kosuke Kamakari; Kelp Nakata; Noriyoshi Ichijo; Rieko Nakata; Hiroyasu Inoue; Tsuyoshi Goto; Teruo Kawada, Koji is made from grains fermented with Aspergillus oiyzae and is essential for the production of many traditional Japanese foods. Many previous studies have shown that koji contributes to the improvement of dyslipidemia. However, little is known regarding the underlying mechanism of this effect. Furthermore, the compound contributing to the activation of lipid metabolism is unknown. We demonstrated that rice koji extract (RKE) induces the mRNA expression of peroxisome proliferator-activated receptor alpha (PPAR alpha) target genes, which promotes lipid metabolism in murine hepatocytes. This effect was not observed in PPAR alpha-KO hepatocytes. We also demonstrated that RKE contained linolenic acid (LIA), oleic acid (OA), and hydroxyoctadecadienoic acids (HODEs), which activate PPAR alpha, using LC-MS analysis. Our findings suggest that RKE, containing LIA, OA, and HODEs, could be valuable in improving dyslipidemia via PPAR alpha activation., Nov. 2016, 64, 46, 8848, 8856, Scientific journal
  • Refereed, SCIENTIFIC REPORTS, NATURE PUBLISHING GROUP, Single ingestion of soy beta-conglycinin induces increased postprandial circulating FGF21 levels exerting beneficial health effects, Tsutomu Hashidume; Asuka Kato; Tomohiro Tanaka; Shoko Miyoshi; Nobuyuki Itoh; Rieko Nakata; Hiroyasu Inoue; Akira Oikawa; Yuji Nakai; Makoto Shimizu; Jun Inoue; Ryuichiro Sato, Soy protein beta-conglycinin has serum lipid-lowering and anti-obesity effects. We showed that singleingestion of beta-conglycinin after fasting alters gene expression in mouse liver. A sharp increase in fibroblast growth factor 21 (FGF21) gene expression, which is depressed by normal feeding, resulted in increased postprandial circulating FGF21 levels along with a significant decrease in adipose tissue weights. Most increases in gene expressions, including FGF21, were targets for the activating transcription factor 4 (ATF4), but not for peroxisome proliferator-activated receptor a. Overexpression of a dominant-negative form of ATF4 significantly reduced beta-conglycinin-induced increases in hepatic FGF21 gene expression. In FGF21-deficient mice, beta-conglycinin effects were partially abolished. Methionine supplementation to the diet or primary hepatocyte culture medium demonstrated its importance for activating liver or hepatocyte ATF4-FGF21 signaling. Thus, dietary beta-conglycinin intake can impact hepatic and systemic metabolism by increasing the postprandial circulating FGF21 levels., Jun. 2016, 6, 28183, Scientific journal

  • Refereed, JOURNAL OF LIPID RESEARCH, AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, Metabolomics reveal 1-palmitoyl lysophosphatidylcholine production by peroxisome proliferator-activated receptor alpha, Haruya Takahashi; Tsuyoshi Goto; Yota Yamazaki; Kosuke Kamakari; Mariko Hirata; Hideyuki Suzuki; Daisuke Shibata; Rieko Nakata; Hiroyasu Inoue; Nobuyuki Takahashi; Teruo Kawada, PPAR is well known as a master regulator of lipid metabolism. PPAR activation enhances fatty acid oxidation and decreases the levels of circulating and cellular lipids in obese diabetic patients. Although PPAR target genes are widely known, little is known about the alteration of plasma and liver metabolites during PPAR activation. Here, we report that metabolome analysis-implicated upregulation of many plasma lysoGP species during bezafibrate (PPAR agonist) treatment. In particular, 1-palmitoyl lysophosphatidylcholine [LPC(16:0)] is increased by bezafibrate treatment in both plasma and liver. In mouse primary hepatocytes, the secretion of LPC(16:0) increased on PPAR activation, and this effect was attenuated by PPAR antagonist treatment. We demonstrated that Pla(2)g7 gene expression levels in the murine hepatocytes were increased by PPAR activation, and the secretion of LPC(16:0) was suppressed by Pla(2)g7 siRNA treatment. Interestingly, LPC(16:0) activates PPAR and induces the expression of PPAR target genes in hepatocytes. Furthermore, we showed that LPC(16:0) has the ability to recover glucose uptake in adipocytes induced insulin resistance. These results reveal that LPC(16:0) is induced by PPAR activation in hepatocytes; LPC(16:0) contributes to the upregulation of PPAR target genes in hepatocytes and the recovery of glucose uptake in insulin-resistant adipocytes., Feb. 2015, 56, 2, 254, 265, Scientific journal
  • Refereed, PloS one, The 4'-hydroxyl group of resveratrol is functionally important for direct activation of PPARα., Yoshie Takizawa; Rieko Nakata; Kiyoshi Fukuhara; Hiroshi Yamashita; Hideo Kubodera; Hiroyasu Inoue, Long-term moderate consumption of red wine is associated with a reduced risk of developing lifestyle-related diseases such as cardiovascular disease and cancer. Therefore, resveratrol, a constituent of grapes and various other plants, has attracted substantial interest. This study focused on one molecular target of resveratrol, the peroxisome proliferator activated receptor α (PPARα). Our previous study in mice showed that resveratrol-mediated protection of the brain against stroke requires activation of PPARα; however, the molecular mechanisms involved in this process remain unknown. Here, we evaluated the chemical basis of the resveratrol-mediated activation of PPARα by performing a docking mode simulation and examining the structure-activity relationships of various polyphenols. The results of experiments using the crystal structure of the PPARα ligand-binding domain and an analysis of the activation of PPARα by a resveratrol analog 4-phenylazophenol (4-PAP) in vivo indicate that the 4'-hydroxyl group of resveratrol is critical for the direct activation of PPARα. Activation of PPARα by 5 μM resveratrol was enhanced by rolipram, an inhibitor of phosphodiesterase (PDE) and forskolin, an activator of adenylate cyclase. We also found that resveratrol has a higher PDE inhibitory activity (IC50 = 19 μM) than resveratrol analogs trans-4-hydroxystilbene and 4-PAP (IC50 = 27-28 μM), both of which has only 4'-hydroxyl group, indicating that this 4'-hydroxyl group of resveratrol is not sufficient for the inhibition of PDE. This result is consistent with that 10 μM resveratrol has a higher agonistic activity of PPARα than these analogs, suggesting that there is a feedforward activation loop of PPARα by resveratrol, which may be involved in the long-term effects of resveratrol in vivo., 2015, 10, 3, e0120865, Scientific journal, True

  • Refereed, ENDOCRINE METABOLIC & IMMUNE DISORDERS-DRUG TARGETS, BENTHAM SCIENCE PUBL LTD, Resveratrol Targets in Inflammation, Hiroyasu Inoue; Rieko Nakata, Resveratrol, a constituent of grapes and various other plants, has been an attractive compound for biomedical studies because moderate long-term drinking of red wine is associated with a reduced risk of lifestyle-related diseases, such as cardiovascular diseases and cancer. Resveratrol is as a phytoalexin, cyclooxygenase (COX) suppressor, and an activator of peroxisome proliferator-activated receptor (PPAR) and SIRT1. As a major phytoalexin, resveratrol is produced by plants in response to various environmental stresses, such as pathogens and ultraviolet (UV) radiation, and promotes resistance to these stresses. A similar active ingredient, salicylic acid (SA), is also produced by plants. Aspirin, acetylated SA, is a major nonsteroidal anti-inflammatory drug (NSAID) because it inhibits COX activity in humans. The jasmonic acid (JA) pathway in plants and the COX pathway in humans are both defense systems against environmental stresses and involve lipid mediators derived from phospholipids. We can hypothesize that there is a molecular basis for the mutually beneficial relationship between plants and humans, which is important for understanding the mode of action of resveratrol in inflammation. Here we provide a review of the studies on resveratrol, especially with respect to the role of COX and PPAR in inflammation., 2015, 15, 3, 186, 195, Scientific journal

Here, we produced and analyzed a transgenic Qdpr (/) mouse model. Unexpectedly, the BH4 contents in the Qdpr (/) mice were not decreased and even increased in some tissues, whereas those of the oxidized form dihydrobiopterin (BH2) were significantly increased. We demonstrated that unlike the wild-type mice, dihydrofolate reductase regenerated BH4 from BH2 in the mutants. Furthermore, we revealed wide alterations in folate-associated metabolism in the Qdpr (/) mice, which suggests an interconnection between folate and biopterin metabolism in the transgenic mouse model.

  • Refereed, PHOTOCHEMISTRY AND PHOTOBIOLOGY, WILEY-BLACKWELL, Possible Involvement of a Tetrahydrobiopterin in Photoreception for UV-B-induced Anthocyanin Synthesis in Carrot, Junko Takeda; Rieko Nakata; Hiroshi Ueno; Akio Murakami; Mineo Iseki; Masakatsu Watanabe, Our previous studies of action spectra for UV-B-induced anthocyanin accumulation in cultured carrot cells indicated that a reduced form of pterin, possibly tetrahydrobiopterin, contributes to UV-B photoreception. In this report, we provide additional evidence for the involvement of pterin in UV-B light sensing. UV-B-induced phenylalanine ammonia-lyase (PAL) activity was considerably suppressed by N-acetylserotonin (an inhibitor of tetrahydrobiopterin biosynthesis), and this suppression was partially recovered by adding biopterin or tetrahydrobiobiopterin. In addition, protein(s) specifically bound to biopterin were detected by radiolabeling experiments in N-acetylserotonin-treated cells. Furthermore, diphenyleneiodonium, a potent inhibitor of electron transfer, completely suppressed UV-B-induced PAL activity. These results suggest the occurrence of an unidentified UV-B photoreceptor (other than UVR8, the tryptophan-based UV-B sensor originally identified in Arabidopsis) with reduced pterin in carrot cells. After reexamining published action spectra, we suggest that anthocyanin synthesis is coordinately regulated by these two UV-B sensors., Sep. 2014, 90, 5, 1043, 1049, Scientific journal
  • Refereed, LEUKEMIA & LYMPHOMA, INFORMA HEALTHCARE, Plasma homocysteine, methionine and S-adenosylhomocysteine levels following high-dose methotrexate treatment in pediatric patients with acute lymphoblastic leukemia or Burkitt lymphoma: association with hepatotoxicity, Masaru Kubota; Rieko Nakata; Souichi Adachi; Ken-Ichiro Watanabe; Toshio Heike; Yasufumi Takeshita; Midori Shima, This study aimed to investigate: (i) changes of plasma homocysteine, methionine and S-adenosylhomocysteine levels following high-dose methotrexate (HD-MTX) treatment and (ii) the correlation of these sulfur-containing amino acids with MTX-induced hepatotoxicity. Fifteen pediatric patients with acute lymphoblastic leukemia and one patient with Burkitt lymphoma, with a total of 26 treatment courses of HD-MTX, were enrolled. Homocysteine levels increased at 24 h after HD-MTX treatment, and showed marginal decreases at 48 and 72 h. Methionine levels showed a biphasic pattern, i. e. an initial decrease at 24 h followed by increases at 48 and 72 h. S-adenosylhomocysteine exhibited a marginal decrease at 24 h. Changes of homocysteine exhibited significant correlation only with a maximum increase of alanine aminotransferase or total bilirubin from baseline. This study has demonstrated, for the first time, simultaneous changes of plasma homocysteine, methionine and S-adenosylhomocysteine following HD-MTX. The potential of homocysteine as a marker of hepatotoxicity is also presented., Jul. 2014, 55, 7, 1591, 1595, Scientific journal
  • Not Refereed, AMERICAN JOURNAL OF PHYSIOLOGY-ENDOCRINOLOGY AND METABOLISM, AMER PHYSIOLOGICAL SOC, Role of AMPK and PPAR gamma 1 in exercise-induced lipoprotein lipase in skeletal muscle, Takashi Sasaki; Rieko Nakata; Hiroyasu Inoue; Makoto Shimizu; Jun Inoue; Ryuichiro Sato, Exercise can effectively ameliorate type 2 diabetes and insulin resistance. Here we show that the mRNA levels of one of peroxisome proliferator-activated receptor (PPAR) family members, PPAR gamma 1, and genes related to energy metabolism, including PPAR gamma coactivator-1 protein-1 alpha (PGC-1 alpha) and lipoprotein lipase (LPL), increased in the gastrocnemius muscle of habitual exercise-trained mice. When mice were intraperitoneally administered an AMP-activated protein kinase (AMPK) activator 5-aminoimidazole-4-carboxamide ribonucleoside (AICAR), the mRNA levels of the aforementioned three genes increased in gastrocnemius muscle. AICAR treatment to C2C12 differentiated myotubes also increased PPAR gamma 1 mRNA levels, but not PPAR alpha and -delta mRNA levels, concomitant with increased PGC-1 alpha mRNA levels. An AMPK inhibitor, compound C, blocked these AICAR effects. AICAR treatment increased the half-life of PPAR gamma 1 mRNA nearly threefold (4-12 h) by activating AMPK. When C2C12 myoblast cells infected with a PPAR gamma 1 expression lentivirus were differentiated into myotubes, PPAR gamma 1 overexpression dramatically increased LPL mRNA levels more than 40-fold. In contrast, when PPAR gamma 1 expression was suppressed in C2C12 myotubes, LPL mRNA levels were significantly reduced, and the effect of AICAR on increased LPL gene expression was almost completely blocked. These results indicated that PPAR gamma was intimately involved in LPL gene expression in skeletal muscle and the AMPK-PPAR gamma 1 pathway may play a role in exercise-induced LPL expression. Thus, we identified a novel critical role for PPAR gamma 1 in response to AMPK activation for controlling the expression of a subset of genes associated with metabolic regulation in skeletal muscle., May 2014, 306, 9, E1085, E1092, Scientific journal

  • Not Refereed, British Journal of Nutrition, Up-regulation of endothelial nitric oxide synthase (eNOS), silent mating type information regulation 2 homologue 1 (SIRT1) and autophagy-related genes by repeated treatments with resveratrol in human umbilical vein endothelial cells, Yoshie Takizawa; Yukiko Kosuge; Hiroyo Awaji; Emi Tamura; Ayako Takai; Takaaki Yanai; Reiko Yamamoto; Koichi Kokame; Toshiyuki Miyata; Rieko Nakata; Hiroyasu Inoue, Resveratrol, a polyphenolic phytoalexin found in red wine and various plants, has been reported to up-regulate the expression of endothelial NO synthase (eNOS) in human umbilical vein endothelial cells (HUVEC). However, this effect was neither long term in nature nor physiologically relevant at the concentration of resveratrol studied. In the present study, we investigated the effects of repeated treatments with a lower concentration of resveratrol on the expression of genes in HUVEC. The expression levels of eNOS and silent mating type information regulation 2 homologue 1 (SIRT1) were up-regulated in HUVEC by repeated treatments with 1 μm-resveratrol for 6 d, but not with fenofibrate. Moreover, resveratrol treatment increased the expression of autophagy-regulated genes such as γ-aminobutyric acid A receptor-associated protein (GABARAP), microtubule-associated protein 1 light chain 3B (LC3B) and autophagy-related protein 3 (ATG3), the radical scavenger activity-related metallothionein-1X (MT1X) gene and the anti-inflammatory activity-related annexin A2 (ANXA) gene. In addition, resveratrol treatment down-regulated the expression of the cell-cycle checkpoint control RAD9 homologue B (RAD9B) gene. These results indicate the beneficial effects of resveratrol on the cardiovascular system. © The Authors 2013., 28 Dec. 2013, 110, 12, 2150, 2155, Scientific journal
  • Not Refereed, JOURNAL OF LIPID RESEARCH, AMER SOC BIOCHEMISTRY MOLECULAR BIOLOGY INC, DHA attenuates postprandial hyperlipidemia via activating PPAR alpha in intestinal epithelial cells, Rino Kimura; Nobuyuki Takahashi; Shan Lin; Tsuyoshi Goto; Kaeko Murota; Rieko Nakata; Hiroyasu Inoue; Teruo Kawada, It is known that peroxisome proliferator-activated receptor (PPAR)alpha, whose activation reduces hyperlipidemia, is highly expressed in intestinal epithelial cells. Docosahexaenoic acid (DHA) could improve postprandial hyperlipidemia, however, its relationship with intestinal PPAR alpha activation is not revealed. In this study, we investigated whether DHA can affect postprandial hyperlipidemia by activating intestinal PPAR alpha using Caco-2 cells and C57BL/6 mice. The genes involved in fatty acid (FA) oxidation and oxygen consumption rate were increased, and the secretion of triacylglyceride (TG) and apolipoprotein B (apoB) was decreased in DHA-treated Caco-2 cells. Additionally, intestinal FA oxidation was induced, and TG and apoB secretion from intestinal epithelial cells was reduced, resulting in the attenuation of plasma TG and apoB levels after oral administration of olive oil in DHA-rich oil-fed mice compared with controls. However, no increase in genes involved in FA oxidation was observed in the liver. Furthermore, the effects of DHA on intestinal lipid secretion and postprandial hyperlipidemia were abolished in PPAR alpha knockout mice. In conclusion, the present work suggests that DHA can inhibit the secretion of TG from intestinal epithelial cells via PPAR alpha activation, which attenuates postprandial hyperlipidemia., Dec. 2013, 54, 12, 3258, 3268, Scientific journal
  • Not Refereed, FEBS LETTERS, ELSEVIER SCIENCE BV, Secretion of miraculin through the function of a signal peptide conserved in the Kunitz-type soybean trypsin inhibitor family, Ayako Takai; Makiko Satoh; Tomomi Matsuyama; Akane Ito; Rieko Nakata; Takashi Aoyama; Hiroyasu Inoue, Miraculin, a glycoprotein that modifies sour tastes into sweet ones, belongs to the Kunitz-type soybean trypsin inhibitor (STI) family. To clarify the functional relation of miraculin with Kunitz-type STIs, we investigated its subcellular localization and trypsin inhibitory activity. In transgenic Arabidopsis thaliana, miraculin, fused to yellow fluorescent protein, localized to and outside the plasma membrane depending on the putative secretion signal peptide. When transgenic seedlings were cultured in liquid medium, miraculin was present in the supernatant only after cellulase treatment. No trypsin inhibitory activity was detected in native or recombinant miraculin. In conclusion, miraculin is secreted outside the plasma membrane through the function of a signal peptide, conserved in Kunitz-type STIs, whereas its trypsin inhibitory activity may be lost during its evolution.

  • Not Refereed, Food Science and Technology Research, Evaluation of food-derived functional ingredients according to activation of PPAR and suppression of COX-2 expression, Rieko Nakata; Yoshie Takizawa; Ayako Takai; Hiroyasu Inoue, The peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors belonging to the nuclear receptor family. They are considered molecular targets for the prevention of lifestyle-related diseases and are involved in the control of cyclooxygenase (COX)-2 expression. COX-2, the rate-limiting enzyme in prostaglandin biosynthesis, plays a key role in inflammation and circulatory homeostasis, and its expression is partly controlled by PPAR. We have identified several natural chemicals, such as resveratrol, that activate PPARs and suppress COX-2 expression. In this review, we provide an evaluation of food-derived functional ingredients that target PPARs and COX-2., 2013, 19, 3, 339, 345

  • Not Refereed, JOURNAL OF FOOD SCIENCE, WILEY-BLACKWELL, The Beneficial Effect of Folate-Enriched Egg on the Folate and Homocysteine Levels in Rats Fed a Folate- and Choline-Deficient Diet, Ayami Sugiyama; Hiroyo Awaji; Kenji Horie; Mujo Kim; Rieko Nakata, We investigated the effects of folate-enriched egg yolk powder on folate and homocysteine levels in plasma and liver of rats fed the folate- and choline-deficient diet to determine bioavailability in vivo. Three-wk-old Wistar rats were fed (1) the pteroylglutamate (PteGlu), (2) the choline, (3) the PteGlu and choline, (4) the folate-enriched egg yolk powder diet for 4 wk after having been fed the folate-and choline-deficient diet. The hepatic folate level in the folate-enriched egg yolk powder group was significantly higher than that in the folate-and choline-deficient or the control groups. The homocysteine concentration in plasma and liver of the folate-enriched egg yolk powder group was significantly lower than that of the folate-and choline-deficient or the PteGlu groups. The S-adenosyl-methionine (SAM)/S-adenosyl-homocysteine (SAH) ratio in the folate-enriched egg yolk powder group was significantly higher than that in the folate-and choline-deficient group. These effects were similar in the PteGlu and choline, but not the PteGlu or the choline groups. These data suggest that the intake of folate-enriched eggs, as well as of both folate and choline, induced the beneficial effects on folate and homocysteine metabolism. Thus, folate-enriched eggs could be used as beneficial source of folate with a high bioavailability., Dec. 2012, 77, 12, H268, H272, Scientific journal
  • Not Refereed, BIOLOGICAL & PHARMACEUTICAL BULLETIN, PHARMACEUTICAL SOC JAPAN, Recent Advances in the Study on Resveratrol, Rieko Nakata; Satoru Takahashi; Hiroyasu Inoue, Appropriate long-term drinking of red wine is associated with a reduced risk for lifestyle-related diseases such as cardiovascular disease and cancer, making resveratrol, a constituent of grapes and various other plants, an attractive compound to be studied. Historically, resveratrol has been identified as a phytoalexin, antioxidant, cyclooxygenase (COX) inhibitor, peroxisome proliferator-activated receptor (PPAR) activator, endothelial nitric oxide synthase (eNOS) inducer, silent mating type information regulation 2 homolog I (SIRT1) activator, and more. Despite scepticism concerning the biological availability of resveratrol, a growing body of in viva evidence indicates that resveratrol has protective effects in several stress and disease models. Here, we provide a review of the studies on resveratrol, especially with respect to COX, PPAR, and eNOS activities, and discuss its potential for promoting human health., Mar. 2012, 35, 3, 273, 279

Farnesol, an isoprenoid, improves metabolic abnormalities in mice via both PPAR alpha-dependent and -independent pathways. Am J Physiol Endocrinol Metab 301: E1022-E1032, 2011. First published August 23, 2011; doi:10.1152/ajpendo.00061.2011.-Peroxisome proliferator-activated receptors (PPARs) control energy homeostasis. In this study, we showed that farnesol, a naturally occurring ligand of PPARs, could ameliorate metabolic diseases. Obese KK-Ay mice fed a high-fat diet (HFD) containing 0.5% farnesol showed significantly decreased serum glucose level, glucosuria incidence, and hepatic triglyceride contents. Farnesol-containing HFD upregulated the mRNA expressions of PPAR alpha target genes involved in fatty acid oxidation in the liver. On the other hand, farnesol was not effective in upregulating the mRNA expressions of PPAR gamma target genes in white adipose tissues. Experiments using PPAR alpha-deficient [(-/-)] mice revealed that the upregulation of fatty acid oxidation-related genes required PPAR alpha function, but the suppression of hepatic triglyceride accumulation was partially PPAR alpha dependent. In hepatocytes isolated from the wild-type and PPAR alpha (-/-) mice, farnesol suppressed triglyceride synthesis. In luciferase assay, farnesol activated both PPAR alpha and the farnesoid X receptor (FXR) at similar concentrations. Moreover, farnesol increased the mRNA expression level of a small heterodimer partner known as one of the FXR target genes and decreased those of sterol regulatory element-binding protein-1c and fatty acid synthase in both the wildtype and PPAR alpha (-/-) hepatocytes. These findings suggest that farnesol could improve metabolic abnormalities in mice via both PPAR alpha-dependent and -independent pathways and that the activation of FXR by farnesol might contribute partially to the PPAR alpha-independent hepatic triglyceride content-lowering effect. To our knowledge, this is the first study on the effect of the dual activators of PPAR alpha and FXR on obesity-induced metabolic disorders., Nov. 2011, 301, 5, E1022, E1032, Scientific journal

  • Not Refereed, APPETITE, ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, Skipping breakfast is associated with reproductive dysfunction in post-adolescent female college students, Tomoko Fujiwara; Rieko Nakata, Although increasing attention has been paid to the adverse effects of skipping breakfast on quality of life, there are very few reports concerning the relationship between skipping breakfast and reproductive function. Therefore, we examined this issue by conducting a questionnaire survey of female college students aged from 18 to 20 years old. The 5 annual surveys of questionnaire demonstrated that the severity of dysmenorrhea was significantly higher in the population that skipped breakfast. The incidence of irregular menses was also higher in the population that skipped breakfast, although there was no difference in the incidence of premenstrual symptoms. The group that skipped breakfast showed a tendency to suffer from constipation. In addition, despite no difference in body mass index, there was a significantly higher incidence of a self-perception of poor general health among the group that skipped breakfast. These findings suggest that skipping breakfast is associated with menstrual disorders, and affects the physical condition of female college students who are undergoing post-adolescent maturation. Since these menstrual disorders may influence the quality of life of young women not only in the present but also in the future, skipping breakfast should be re-evaluated from the perspective of future reproductive function.

  • Not Refereed, BIOCHIMICA ET BIOPHYSICA ACTA-MOLECULAR AND CELL BIOLOGY OF LIPIDS, ELSEVIER SCIENCE BV, Citral, a component of lemongrass oil, activates PPAR alpha and gamma and suppresses COX-2 expression, Michiko Katsukawa; Rieko Nakata; Yoshie Takizawa; Kazuyuki Hori; Saori Takahashi; Hiroyasu Inoue, Lemongrass is a widely used herb as a food flavoring, as a perfume, and for its analgesic and anti-inflammatory purposes; however, the molecular mechanisms of these effects have not been elucidated. Previously, we identified carvacrol from the essential oil of thyme as a suppressor of cyclooxygenase (COX)-2, a key enzyme for prostaglandin synthesis, and also an activator of peroxisome proliferator-activated receptor (PPAR), a molecular target for "lifestyle-related" diseases. In this study, we evaluated the essential oil of lemongrass using our established assays for COX-2 and PPARs. We found that COX-2 promoter activity was suppressed by lemongrass oil in cell-based transfection assays, and we identified citral as a major component in the suppression of COX-2 expression and as an activator of PPAR alpha and gamma. PPAR gamma-dependent suppression of COX-2 promoter activity was observed in response to citral treatment In human macrophage-like U937 cells, citral suppressed both U'S-induced COX-2 mRNA and protein expression, dose-dependently. Moreover, citral induced the mRNA expression of the PPAR alpha-responsive carnitine palmitoyltransferase 1 gene and the PPAR gamma-responsive fatty acid binding protein 4 gene, suggesting that citral activates PPAR alpha and gamma, and regulates COX-2 expression. These results are important for understanding the anti-inflammatory and anti-lifestyle-related disease properties of lemongrass. (C) 2010 Elsevier B.V.

Resveratrol, a well-known SIRT1 activator is considered to be one of the beneficial components contained in red wine, and also developed as a drug candidate. We previously demonstrated that resveratrol protects brain against ischemic stroke in mice through a PPAR alpha-dependent mechanism. Here we report the different effects of the oligomers of resveratrol. Methods: We evaluated the activation of PPARs by epsilon-viniferin, a resveratrol dimer, and vaticanol C, a resveratrol tetramer, in cell-based reporter assays using bovine arterial endothelial cells, as well as the activation of SIRT1. Moreover, we tested the metabolic action by administering vaticanol C with the high fat diet to wild-type and PPAR alpha-knockout male mice for eight weeks. Results: We show that vaticanol C activates PPAR alpha and PPAR beta/delta in cell-based reporter assays, but does not activate SIRT1. epsilon-Viniferin shows a similar radical scavenging activity as resveratrol, but neither effects on PPARs and SIRT-1. Eight-week intake of vaticanol C with a high fat diet upregulates hepatic expression of PPAR alpha-responsive genes such as cyp4a10, cyp4a14 and FABP1, and skeletal muscle expression of PPAR beta/delta-responsive genes, such as UCP3 and PDK4 ( pyruvate dehydrogenase kinase, isoform 4), in wild-type, but not PPAR alpha-knockout mice. Conclusion: Vaticanol C, a resveratrol tetramer, activated PPAR alpha and PPAR beta/delta in vitro and in vivo. These findings indicate that activation of PPAR alpha and PPAR beta/delta by vaticanol C may be a novel mechanism, affording beneficial effects against lifestyle-related diseases., May 2010, 7, 46, Scientific journal

Peroxisome proliferator-activated receptors (PPARs) are ligand-dependent transcription factors belonging to the nuclear receptor superfamily and are involved in the control of COX-2 expression, and vice versa. Here, we show that COX-2 promoter activity was suppressed by essential oils derived from thyme, clove, rose, eucalyptus, fennel, and bergamot in cell-based transfection assays using bovine arterial endothelial cells. Moreover, from thyme oil, we identified carvacrol as a major component of the suppressor of COX-2 expression and an activator of PPAR alpha and gamma. PPAR gamma-dependent suppression of COX-2 promoter activity was observed in response to carvacrol treatment. In human macrophage-like U937 cells, carvacrol suppressed lipopolysaccharide-induced COX-2 mRNA and protein expression, suggesting that carvacrol regulates COX-2 expression through its agonistic effect on PPAR alpha.

This homodimer protein consists of two glycosylated polypeptides that are cross-linked by a disulfide bond. Recently, functional expression of miraculin was reported in host cells with the ability to glycosylate proteins, such as lettuce, tomato and the microbe Aspergillus oryzae, but not Escherichia coli. Thus, a question remains as to whether glycosylation of miraculin is essential for its taste-modifying properties. Here we show that recombinant miraculin expressed in E. coli has taste-modifying properties as a homodimer, not as a monomer, indicating that glycosylation is not essential for the taste-modifying property., Apr. 2009, 145, 4, 445, 450, Scientific journal

Subjects were recruited from 315 college students and were classified as: Group I, eating breakfast; Group II, skipping breakfast; Group III, not eating fast foods; Group IV, eating fast foods; Group V, not eating processed foods; and Group VI, eating processed foods. The intensity of dysmenorrhea was scored using three grades. All participants were further divided into groups based on having regular or irregular menstruation, having premenstrual symptoms or not, and self-perception of good or poor general health. General health was poor in Groups II and VI, and dysmenorrhea scores were high in Groups II, IV and VI. The incidence of irregular menses was also high in Group II. However, there was no apparent relation between premenstrual symptoms and dietary habits. These findings suggest that skipping breakfast adversely affects menstrual disorders in young college students., 2009, 60, S6, 23, 31, Scientific journal

Recent studies have shown that COX-2 was involved not only in inflammation, but also in tumorigenesis and lifestyle-related diseases. We have been investigating the regulation of the COX-2 gene, and found that several chemicals derived from plants such as resveratrol (grapes) suppressed COX-2 gene expression. In this present study, 21 plant oils were evaluated for their suppressive effect on COX-2 gene expression by using a transient transfection assay of the luciferase reporter vector containing the human COX-2 promoter into arterial endothelial cells. We found that the COX-2 promoter activity was suppressed by origanum (65%), clove (40%), rose (30%), eucalyptus (25%), fennel (22%) and bergamot oils (21%) in descending order, suggesting that these oils function as suppressors of COX-2 gene expression, and that this assay system would be useful to identify novel functional components in food materials., 2008, 59, 6, 373, 378

The rats were fed a test diet containing folic acid at a dose of 8 (control) or 0.5 (low folate) mg/kg. After a 4-week feeding, the plasma homocysteine concentration in the low-folate group increased to 1.6-fold that in the control group. Betaine supplementation (30 g/kg diet) significantly suppressed the plasma homocysteine level elevation and led to an upward trend in liver betaine-homocysteine methyltransferase (BHMT) activity, whereas no change was observed with supplementation with choline (10 g/kg diet), a precursor of betaine. The results of this study suggest that betaine suppresses the plasma homocysteine level elevation induced by low folate intake, and the suppression is associated with the metabolic pathway driven by BHMT.

Rats were fed an experimental diet containing 5% bctaine for 4wk and methionine was intravenously administered. The elevations of plasma homocysteine were assessed by comparing the increments to the initial measured value and the positive incremental area under the plasma homocysteine concentration curve over the 240-min post-methionine-loading period (Delta AUC(0-240)). In the betaine-ingesting rats, Delta AUC(0-240) was significantly lower than in the control group (48% of the control), and the increments of plasma homocysteine were also lower compared with the control, especially 15-30 min after methionine loading. Choline, a precursor of betaine, did not alter the plasma homocysteme elevation. In a definite period immediately after methionine loading, carnitine, a methyl-group-rich amino acid, induced a significant increase of plasma homocysteme, compared to the control. Moreover, plasma homocysteine concentration was significantly decreased by 4 wk of betaine ingestion. Betaine enhanced liver BHMT activity whereas choline and carnitine did not show any effects on BHMT activity. These results suggest that betaine contributes to both the decrease in the plasma homocysteine concentration and the suppression of plasma homocysteine elevation through the activation of liver BHMT., Jun. 2006, 52, 3, 194, 199, Scientific journal

The plasma homocysteine concentrations significantly increased 5-120 minutes after 0.34 mmol/kg of methionine loading and then returned to the baseline within 240 minutes. Betaine was then intravenously administered at the same time as the methionine loading. The total increment of plasma homocysteine was assessed using the positive incremental area under the plasma homocysteine concentration curve over the 240-minute post-methionine-loading period (DeltaAUC(0-240)). Betaine reduced DeltaAUC(0-240) dose-dependently: 81% of the control by 1.7 mmol/kg of betaine and 33% by 3.4 mmol/kg. The effects of glycine and methylglycine, analogues of betaine, were also investigated. As observed for betaine, methylglycine decreased DeltaAUC(0-240) to 44% of the control, whereas glycine showed no significant effect on DeltaAUC(0-240), indicating that methyl groups of betaine and dimethylglycine were necessary to suppress plasma homocysteine elevation. These results suggest that betaine contributes to the suppression of plasma homocysteine elevation by promoting homocysteine metabolism, and seems to work as a methyl donor. (C) 2004 Elsevier Inc.

  • Not Refereed, Reproductive Medicine and Biology, John Wiley and Sons Ltd, Current problems of food intake in young women in Japan: Their influence on female reproductive function, Tomoko Fujiwara; Rieko Nakata, Accumulating evidence suggests that food customs are associated with quality of life in women of the reproductive age. In Japan, dietary limitation for cosmetic purposes, skipping food intake, intake of processed foods and the shift from Japanese to Westernized style food have increased among young women. These changes in food habits can cause inadequate intake of calories, micronutrients, unsaturated fat, phytestrogens and fiber as well as increasing environmental toxins. Furthermore, these food habits increase risk as a result of intake of food additives, anti-oxidants, processing agents and sweeteners, which have been demonstrated to be harmful to human health. These factors are speculated to not only influence the present lifestyle, but also to induce gynecologic disorders such as dysmenorrhea and irregular menstruation. The adverse effects of these dietary habits on pregnancy outcome and carcinogenesis of breast and ovarian cancers have also been demonstrated. In addition, latent development of organic diseases such as endometriosis, which are accompanied by dysmenorrhea, is a concern under the current nutritional environment in young women. Thus, it is an urgent issue to evaluate the present situation of eating habits in young Japanese women and estimate the influence of these habits on the quality of life including reproductive functions., 2004, 3, 3, 107, 114

However, the termination mechanism in liver regeneration has not been thoroughly studied. In this paper, we report that the activity of liver caspase-3-like protease, which is specifically activated in apoptosis, increases 18, 36, and 48 hr after PH during maximal hepatocyte proliferative activity. This is the first study that shows the activation of an apoptosis-executing enzyme during physiological liver regeneration. These results suggest that apoptosis is induced in each surge of DNA synthesis as the termination mechanism. When phenoxybenzamine, an alpha -blocker that has been reported to inhibit DNA synthesis during liver regeneration, was injected 8 hr after PH, the caspase-3-like activity in the liver peaked at 15 hr after PH and the enzyme activity also increased in plasma at 18 and 24 hr after PH in sharp contrast to the case of normal regeneration. These results indicate that extensive apoptosis is caused by phenoxybenzamine and that the secondary necrosis of apoptotic cells results in the increase of caspase-3-like protease activity in the plasma.

The rats were divided into four groups which were fed an experimental diet for 38 days ad libitum (A) every day, 80% diet of group A every day (R80), 100 and 60% diets of group A on alternate days (R100-60), and 120 and 40% diets of group A on alternate days (R120-40), respectively. Body weight gain was significantly lower in group R120-40 than in the other groups. The weights of internal organs were lower in all the restricted groups than in group A. However, their weight ratios to whole body weight were not significantly different among all the groups. Differences in such daily energy metabolism as total energy expenditure per kg body weight were not significant between group A and group R80, which suggested that the rats in group R80 attained metabolic adaptation to the feeding conditions by diminishing their body size. On the other hand, the rats in group R120-40 changed total energy expenditure (TEE) and minimal energy expenditure (MEE) according to the amount of food ingested on alternate days. They maintained MEE on 120% diet days at a level comparable to that of the rats in group R80 and adapted the present irregular feeding conditions by decreasing total activity (TA). However, the decrease in TA brought about by irregular feeding over a long period of time is considered to be undesirable for health., 1995, 46, 9, 833, 840

(2) Among physiological functions that determine the development of physical strength, thyroid-stimulating hormone (TSH) and growth hormone glasma levels were higher after evening exercise than after morning exercise. (3) The increase in urinary excretion of 3-methylhistidine (degradation index of muscle protein) after exercise was smaller in the evening than in the morning.

  • Refereed, Nutrients, Adolescent Dietary Habit-induced Obstetric and Gynecologic Disease (ADHOGD) as a New Hypothesis-Possible Involvement of Clock System., Tomoko Fujiwara; Masanori Ono; Michihiro Mieda; Hiroaki Yoshikawa; Rieko Nakata; Takiko Daikoku; Naomi Sekizuka-Kagami; Yoshiko Maida; Hitoshi Ando; Hiroshi Fujiwara, There are growing concerns that poor dietary behaviors at young ages will increase the future risk of chronic diseases in adulthood. We found that female college students who skipped breakfast had higher incidences of dysmenorrhea and irregular menstruation, suggesting that meal skipping affects ovarian and uterine functions. Since dysmenorrhea is more prevalent in those with a past history of dieting, we proposed a novel concept that inadequate dietary habits in adolescence become a trigger for the subsequent development of organic gynecologic diseases. Since inadequate feeding that was limited during the non-active phase impaired reproductive functions in post-adolescent female rats, we hypothesize that circadian rhythm disorders due to breakfast skipping disrupts the hypothalamic-pituitary-ovarian axis, impairs the reproductive rhythm, and leads to ovarian and uterine dysfunction. To explain how reproductive dysfunction is memorized from adolescence to adulthood, we hypothesize that the peripheral clock system also plays a critical role in the latent progression of reproductive diseases together with the central system, and propose naming this concept "adolescent dietary habit-induced obstetric and gynecologic disease (ADHOGD)". This theory will contribute to analyzing the etiologies of and developing prophylaxes for female reproductive diseases from novel aspects. In this article, we describe the precise outline of the above hypotheses with the supporting evidence in the literature., 02 May 2020, 12, 5, True

Methods: Considering that rats are nocturnally active, 8-wk-old female Wistar rats were classified into 3 groups: Fed during the daytime only (nonactive phase), night-time only (active phase), or control group I (without time or calorie restriction, free access to a standard caloric diet, 20.0% protein, 62.9% carbohydrate, and 7.0% fat, 3.95 kcal/g) for 4 wk. The changes in body weight and frequency of ovulation in each group were evaluated by a weight scale and a vaginal smear, respectively. At the end of the period of dietary restriction, ovaries were removed, and the numbers of growing follicles (mean diameter >250 μm) and corpora lutea (>600 μm) were examined using hematoxylin-eosin-stained tissue sections. In addition, 8-wk-old female rats were fed only during the night-time for 4 wk under a 20%-reduced food supply of the control group II (without any restriction). Results: In the daytime-fed group, the frequency and number of ovulations were significantly decreased compared with those in the control group I (P < 0.05), with a reduced body weight gain concomitant with about 20% of reduction in the daily food intake. In contrast, in the night-time-fed group, even when a 20% reduction in the daily food intake was loaded, their estrus cyclicity did not change despite significant reductions in weight gain and food intake compared with control group II. Conclusion: These findings indicate that restricting food intake to the inactive phase impairs ovarian function in postadolescent female rats, suggesting that the timing of food intake during circadian cycle is one of the crucial factors interfering with the reproductive function., Apr. 2019, 3, 4, nzy093, Scientific journal

  • Refereed, Lipids, Springer Berlin Heidelberg, 9-Oxo-10(E),12(Z),15(Z)-Octadecatrienoic Acid Activates Peroxisome Proliferator-Activated Receptor α in Hepatocytes., Takahashi H; Kamakari K; Goto T; Hara H; Mohri S; Suzuki H; Shibata D; Nakata R; Inoue H; Takahashi N; Kawada T, First online: 19 September 2015The peroxisome proliferator-activated receptor (PPAR)α is mainly expressed in the liver and plays an important role in the regulation of lipid metabolism. It has been reported that PPARα activation enhances fatty acid oxidation and reduces fat storage. Therefore, PPARα agonists are used to treat dyslipidemia. In the present study, we found that 9-oxo-10(E), 12(Z), 15(Z)-octadecatrienoic acid (9-oxo-OTA), which is a α-linolenic acid (ALA) derivative, is present in tomato (Solanum lycopersicum) extract. We showed that 9-oxo-OTA activated PPARα and induced the mRNA expression of PPARα target genes in murine primary hepatocytes. These effects promoted fatty acid uptake and the secretion of β-hydroxybutyrate, which is one of the endogenous ketone bodies. We also demonstrated that these effects of 9-oxo-OTA were not observed in PPARα-knockout (KO) primary hepatocytes. To our knowledge, this is the first study to report that 9-oxo-OTA promotes fatty acid metabolism via PPARα activation and discuss its potential as a valuable food-derived compound for use in the management of dyslipidemia., Sep. 2015, 50, 11, 1083, 1091

  • Current developments in nutrition, Time-Restricted Feeding Regulates Circadian Rhythm of Murine Uterine Clock., Takashi Hosono; Masanori Ono; Takiko Daikoku; Michihiro Mieda; Satoshi Nomura; Kyosuke Kagami; Takashi Iizuka; Rieko Nakata; Tomoko Fujiwara; Hiroshi Fujiwara; Hitoshi Ando, Background: Skipping breakfast is associated with dysmenorrhea in young women. This suggests that the delay of food intake in the active phase impairs uterine functions by interfering with circadian rhythms. Objectives: To examine the relation between the delay of feeding and uterine circadian rhythms, we investigated the effects of the first meal occasion in the active phase on the uterine clock. Methods: Zeitgeber time (ZT) was defined as ZT0 (08:45) with lights on and ZT12 (20:45) with lights off. Young female mice (8 wk of age) were divided into 3 groups: group I (ad libitum consumption), group II (time-restricted feeding during ZT12-16, initial 4 h of the active period), and group III (time-restricted feeding during ZT20-24, last 4 h of the active period, a breakfast-skipping model). After 2 wk of dietary restriction, mice in each group were killed at 4-h intervals and the expression profiles of uterine clock genes, Bmal1 (brain and muscle aryl hydrocarbon receptor nuclear translocator-like protein 1), Per1 (period circadian clock 1), Per2, and Cry1 (cryptochrome 1), were examined. Results: qPCR and western blot analyses demonstrated synchronized circadian clock gene expression within the uterus. Immunohistochemical analysis confirmed that BMAL1 protein expression was synchronized among the endometrium and myometrium. In groups I and II, mRNA expression of Bmal1 was elevated after ZT12 at the start of the active phase. In contrast, Bmal1 expression was elevated just after ZT20 in group III, showing that the uterine clock rhythm had shifted 8 h backward. The changes in BMAL1 protein expression were confirmed by western blot analysis. Conclusions: This study is the first to indicate that time-restricted feeding regulates a circadian rhythm of the uterine clock that is synchronized throughout the uterine body. These findings suggest that the uterine clock system is a new candidate to explain the etiology of breakfast skipping-induced uterine dysfunction., May 2021, 5, 5, nzab064, Scientific journal, True

J. Nutr. 2013)。そこで本研究では、ヒトiPS細胞由来心筋細胞を用いてレスベラトロールの心臓への効果を検討した。 方法・結果 拍動したヒトiPS細胞由来心筋細胞にレスベラトロール(10μM)を6日間処理した結果、PPARαおよびβ/δの発現が上昇した。さらに、脂質代謝に関連するPPARα応答遺伝子が誘導され、この結果は低濃度のレスベラトロールを含む赤ワイン凍結乾燥物を長期摂取したマウス心臓での発現誘導と一致していた。また、レスベラトロールによりヒト血管内皮細胞で誘導された遺伝子群の多くは、ヒトiPS細胞由来心筋細胞においても発現上昇が認められた。(共同研究:メルシャン(株)), 2015, 67, 165, 165
  • Abstracts of Annual Congress of The Japan Society of Home Economics, The Japan Society of Home Economics, Imprrovement of lipid metabolism by soybean-derived components targeted to PPAR activation, Nakata Rieko; Hongo Shouko; Takizawa Yoshie; Inoue Hiroyasu, 目的 日本人の食生活において古くから親しまれてきた大豆の成分について、様々な機能性が注目され多くの研究がなされているのが、その分子作用機構の解明は十分ではない。我々は、脂質代謝の関与する核内受容体PPARを指標とした食品成分の機能性評価を続けており、PPAR活性化能を有する成分を同定し、本学会においても報告してきた。そこで本研究では、大豆タンパク質摂取による脂質代謝改善効果とPPAR活性化の関与について、PPARα欠損型マウスを用いて検討した。
    方法および結果 大豆の主要タンパク質であるβ-コングリシニンを20%含む高脂肪食を、4週間マウスに摂取させた。野生型マウスでは、カゼインをタンパク源とした場合に比べて、体重増加抑制や血漿トリグリセリド(TG)濃度の減少が認められた。この効果は、PPARα欠損型マウスでも見られ、PPARα活性化の関与は認められなかった。そこで、大豆タンパク質の栄養値に注目し、第1制限アミノ酸のメチオニンを添加して同様の実験を行った。その結果、PPARα依存的な体重増加抑制、白色脂肪重量の減少、血漿TGおよび遊離脂肪酸濃度の減少が認められた。さらに、肝臓で産生され脂質代謝に関与する因子の遺伝子発現が誘導され、その効果はPPARα依存的であった。以上の結果から、β-コングリシニンはPPARαを活性化し、脂質代謝改善効果を示す可能性が示唆された。, 2015, 67, 163, 163

    【方法】2014年12月に18-20歳の女子大学生を対象に、同意を得た後に自記式アンケート調査を行い、スマートフォンの利用状況と食習慣や健康状態に関して223名から有効回答を得た。
    【結果】スマートフォン利用者の4人にひとりは1日に5時間以上使用し、食事にかける時間や睡眠時間は5時間未満の利用者と変わらなかったものの、食事中の利用率が高く、朝食欠食率も高いという結果が得られた。また、食事中にもスマートフォンを利用する群においては、利用しない群に比べて、ダイエット経験の有無に関わらず体重が増加している者が有意に多いことが示された。これらの知見から、スマートフォンの利用時間が長く、食事中にもスマートフォンを使用すると、食事量の過剰摂取に陥る可能性が示唆され、その原因としてスマートフォンの利用が食事摂取に関する自己認識力を低下させている可能性が推察された。, 2015, 27, 200, 200

The rats were divided into four groups which were fed an experimental diet for 38 days ad libitum (A) every day, 80% diet of group A every day (R80), 100 and 60% diets of group A on alternate days (R100-60), and 120 and 40% diets of group A on alternate days (R120-40), respectively. Body weight gain was significantly lower in group R120-40 than in the other groups. The weights of internal organs were lower in all the restricted groups than in group A. However, their weight ratios to whole body weight were not significantly different among all the groups. Differences in such daily energy metabolism as total energy expenditure per kg body weight were not significant between group A and group R80, which suggested that the rats in group R80 attained metabolic adaptation to the feeding conditions by diminishing their body size. On the other hand, the rats in group R120-40 changed total energy expenditure (TEE) and minimal energy expenditure (MEE) according to the amount of food ingested on alternate days. They maintained MEE on 120% diet days at a level comparable to that of the rats in group R80 and adapted the present irregular feeding conditions by decreasing total activity (TA). However, the decrease in TA brought about by irregular feeding over a long period of time is considered to be undesirable for health., 1995, 46, 9, 833, 840
  • Not Refereed, Vitamins, The Vitamin Society of Japan, Effects of Folic Acid on Rat Liver Regeneration After Partial Hepatectomy, NAKATA Rieko, Effects of folic acid on rat liver regeneration were evaluated by the activities of thymidylate synthase and thymidine kinase, which are rate-limiting enzymes of DNA synthesis in liver regeneration, and the contents of DNA, RNA and protein, and liver weight. By injection of folic acid immediately after partial (70%) hepatectomy, thymidine kinase activity was inhibited in the 24 h-regenerating liver, whereas thymidylate synthase activity increased in the 48 and 72 h-regenerating liver, The DNA and RNA contents and liver weight were also reduced in the 72 h-regenerating liver of folate-injected rats. These results suggest the stimulatory effect of folic acid on the induction of thymidylate synthase and the inhibitory effect on rat liver regeneration., 1994, 68, 8, 445, 449
