Due to its role in regulation of mitochondrial function, PGC1α is emerging as an important player in ageing and neurodegenerative disorders. PGC1α exerts its neuroprotective effects by promoting mitochondrial biogenesis (MB) and functioning. However, the precise regulatory role of PGC1α in the control of mitochondrial dynamics (MD) and neurotoxicity is still unknown. Here we elucidate the role ...
The constitutive androstane receptor (CAR) and peroxisome proliferator-activated receptor gamma coactivator-1α (PGC1α) are master regulators of drug metabolism and gluconeogenesis, respectively. In supporting the cross talk between drug metabolism and energy metabolism, activation of CAR has been shown to suppress hepatic gluconeogenesis and ameliorate hyperglycemia in vivo, but the underlying ...
Peroxisome proliferator-activated receptor-γ coactivator 1-α (PGC1α) is a transcriptional coactivator able to up-regulate mitochondrial biogenesis, respiratory capacity, oxidative phosphorylation, and fatty acid β-oxidation with the final aim of providing a more efficient pathway for aerobic energy production. In the continuously renewed intestinal epithelium, proliferative cells in the crypts ...
Purpose. In this study, we investigated the effect of PGC1α activators on mitochondrial fusion, fission, and autophagic quality control in renal tubular cells in a diabetic environment in vivo and in vitro. We also examined whether the upregulation of PGC1α attenuates diabetic tubulopathy by normalizing mitochondrial homeostasis. Methods. HKC8 cells were subjected to high-glucose conditions (30...
BACKGROUND In our previous studies, we prepared novel oligomannuronate-chromium(III) complexes (OM2, OM4) from marine alginate, and found that these compounds sensitize insulin action better than oligomannuronate(OM), chromium, and metformin in C2C12 skeletal muscle cells. In the present study, we studied their effects on mitochondrial biogenesis, lipid metabolism, and the underlying molecular ...
Orphan nuclear receptor ERRγ is a member of nuclear receptor superfamily that regulates several important cellular processes including hepatic glucose and alcohol metabolism. However, mechanistic understanding of transcriptional regulation of the ERRγ gene remains to be elucidated. Here, we report that activating transcription factor 6α (ATF6α), an endoplasmic reticulum (ER)-membrane-bound basi...
BACKGROUND Inflammatory cytokines play an important role in the pathogenesis of heart failure. We have recently found the cytokine TWEAK (tumor necrosis factor (TNF)-like weak inducer of apoptosis), a member of the TNF superfamily, to be increased in patients with cardiomyopathy and result in the development of heart failure when overexpressed in mice. The molecular mechanisms underlying TWEAK-...
مقدمه: با توجه به نقش PGC1α در متابولیسم گلوکز، آیرزین نیز یک مایوکاین القا شده با فعالیت ورزشی میباشد که با دیابت نوع 2 کاهش مییابد. بیان ژن PGC1α در افراد دیابتی تا 50% کاهش مییابد. هدف از پژوهش حاضر بررسی تأثیر 8 هفته تمرین مقاومتی بر بیان ژن PGC1α، آیرزین، انسولین، گلوکز و مقاومت به انسولین در رتهای دیابتی شده با استرپتوزوتوسین بود. مواد و روشها: در...
هدف از این پژوهش بررسی اثر 8 هفته تمرین استقامتی و رژیم غذائی بر بیان ژن Pgc1α و Ucp1 در بافت چربی موشهای نر چاق و نرمال C57BL/6 میباشد. 48 سر موش نر C57BL/6 به صورت تصادفی به دو گروه تقسیم شدند: 1. گروه تغذیه شده با رژیم غذایی پرچرب، 2. گروه تغذیه شده با رژیم غذایی کم چرب (به مدت 12 هفته). سپس هر دو گروه چاق و نرمال براساس میانگین وزنی برابر به چهار گروه تقسیم شدند: رژیم غذایی پرچرب-تمرین (H...
Expression of the brown adipocyte-specific gene, uncoupling protein 1 (UCP1), is increased by both PPARγ stimulation and cAMP activation through their ability to stimulate the expression of the PPAR coactivator PGC1α. In HIB1B brown preadipocytes, combination of the PPARγ agonist, rosiglitazone, and the cAMP stimulator forskolin synergistically increased UCP1 mRNA expression, but PGC1α expressi...
