مقدمه: تغییر در سوخت و ساز لیپیدها یکی از سازوکارهای مهم برای درمان مقاومت به انسولین و در نتیجه دیابت نوع 2 است. از سوی دیگر، pgc-1α به عنوان یکی از تنظیم کنندههای کلیدی بیوژنز و عملکرد میتوکندری، از راه افزایش بتا- اکسیداسیون لیپیدها، نقش مهمی در بهبود حساسیت به انسولین ایفا میکند. در پژوهش حاضر، اثرات اپیگالوکاتچین گالات (egcg)، به عنوان ترکیب ضدچاقی و افزاینده کاتابولیسم چربی، بر بیان ...

The transcriptional coactivator PGC-1α plays a central role in hepatic gluconeogenesis. We previously reported that alternative splicing of the PGC-1α gene produces an additional transcript encoding the truncated protein NT-PGC-1α NT-PGC-1α is co-expressed with PGC-1α and highly induced by fasting in the liver. NT-PGC-1α regulates tissue-specific metabolism, but its role in the liver has not be...
Pgc-1α and its various isoforms may play a role in determining skeletal muscle mitochondrial adaptations in response to diet. 8 wks of dietary supplementation with the flavonoid quercetin (Q) or red onion extract (ROE) in a high fat diet (HFD) ameliorates HFD-induced obesity and insulin resistance in C57BL/J mice while upregulating Pgc-1α and increasing skeletal muscle mitochondrial number and ...
Brown fat expresses two PGC-1α isoforms (PGC-1α and NT-PGC-1α) and both play a central role in the regulation of cellular energy metabolism and adaptive thermogenesis by interacting with a wide range of transcription factors including PPARγ, PPARα, ERRα, and NRF1. PGC-1α consists of 797 amino acids, whereas alternative splicing of the PGC-1α gene produces a shorter protein called NT-PGC-1α (aa ...
There are three isoforms of peroxisome proliferator-activated receptor-γ coactivator 1α (PGC-1α) mRNA, which promotes mitochondrial biogenesis in skeletal muscles. Compared with PGC-1α-a mRNA, PGC-1α-b or PGC-1α-c mRNA is transcribed by a different exon 1 of the PGC-1α gene. In this study, effects of exercise intensity and 5-aminoimidazole-4-carboxamide-1β-d-ribofuranoside (AICAR) on isoform-sp...
The transcriptional coactivator PGC-1α is a key regulator of cellular energy expenditure in peripheral tissues. Recent studies report that PGC-1α-null mice develop late-onset obesity and that the neuronal inactivation of PGC-1α causes increased food intake. However, the exact role of PGC-1α in the CNS remains unclear. Here we show that PGC-1α directly regulates the expression of the hypothalami...
Background & Objective: Angiopoietin-like Proteins 8 (ANGPTL8) which secreted form adipose tissue due to downstream PGC-1α pathways, is the main factor for regeneration of beta cell. The aim of this study was to investigate the effect of 4 endurance training program on PGC-1α expression in adipose tissue, ANGPTL8 serum concentration and beta cell function (HOMA.B) in diabetic rats. Materials & ...
The transcriptional coactivator peroxisome proliferator-activated receptor γ coactivator (PGC)-1α and its splice variant N terminal (NT)-PGC-1α regulate adaptive thermogenesis by transcriptional induction of thermogenic and mitochondrial genes involved in energy metabolism. We previously reported that full-length PGC-1α (FL-PGC-1α) is dispensable for cold-induced nonshivering thermogenesis in F...
OBJECTIVE Aggregation of α-synuclein (α-syn) and α-syn cytotoxicity are hallmarks of sporadic and familial Parkinson disease (PD), with accumulating evidence that prefibrillar oligomers and protofibrils are the pathogenic species in PD and related synucleinopathies. Peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α), a key regulator of mitochondrial biogenesis and cellular ene...
