Type 2 diabetes mellitus (T2DM) is a chronic disease characterized by glucose metabolic disturbance. A number of transcription factors and coactivators are involved in this process. Peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) is an important transcription coactivator regulating cellular energy metabolism. Accumulating evidence has indicated that PGC-1α is invol...
PPARγ coactivator-1α (PGC-1α) is considered to be a major regulator of mitochondrial biogenesis. Though first discovered in brown adipose tissue, this coactivator has emerged as a coordinator of mitochondrial biogenesis in skeletal muscle via enhanced transcription of many nuclear genes encoding mitochondrial proteins. Stimuli such as exercise provoke the activation of signalling cascades that ...
Cleavage of amyloid precursor protein (APP) by β- and γ-secretase generates amyloid-β (Aβ) and APP intracellular domain (AICD) peptides. Presenilin (PS) 1 or 2 is the catalytic component of the γ-secretase complex. Mitochondrial dysfunction is an established phenomenon in Alzheimer's disease (AD), but the causes and role of PS1, APP, and APP's cleavage products in this process are largely unkno...
BACKGROUND Pepsinogen C (PGC) plays an important role in sustaining the cellular differentiation during the process of gastric carcinogenesis. This study aimed to assess the role of PGC tagSNPs and their interactions with Helicobacter pylori (H. pylori) in the development of gastric cancer and its precursor, atrophic gastritis. METHODS Four PGC tagSNPs (rs6941539, rs6912200, rs3789210 and rs6...
Peroxisome proliferator-activated receptor gamma coactivator (PGC-1alpha) is a transcriptional coactivator that plays a key role in coordinating mitochondrial biogenesis. Recent evidence has linked p38 MAPK and AMPK with activation of PGC-1alpha. It was recently shown in rodent skeletal muscle that acute endurance exercise causes a shift in the subcellular localization of PGC-1alpha from the cy...
A facile hydrothermal assisted in-situ precipitation technique was employed for synthesizing highly efficient porous graphitic carbon/manganese dioxide (PGC/MnO 2 ) nanocomposite adsorbent using calcium alginate as carbon precursor. Morphological and structural characterization scanning electron microscopy equipped with energy dispersive X-ray spectroscopy, transmission , diffraction techniques...
The effect of simulated ischemia [hypoxia, no glucose, extracellular pH (pH(o)) 6.4] on cGMP synthesis induced by stimulation of soluble (sGC) or particulate guanylyl cyclase (pGC) was investigated in adult rat cardiomyocytes. Intracellular cGMP content was measured after stimulation of sGC by S-nitroso-N-penicillamine (SNAP) or stimulation of pGC by natriuretic peptides [urodilatin (Uro), atri...
The nuclear bile acid receptor FXR (farnesoid X receptor) is one of the key factors that suppress bile acid biosynthesis in the liver. PGC-1alpha [PPARgamma (peroxisome-proliferator-activated receptor gamma) co-activator-1alpha] is known to control energy homoeostasis in adipose tissue, skeletal muscle and liver. We performed cell-based reporter assays using the expression system of a GAL4-FXR ...
Thyroid hormone 3,3',5-Triiodo-L-thyronine (T3) is essential for proper brain development. Perinatal loss of T3 causes severe growth defects in neurons and glia, including strong inhibition of dendrite formation in Purkinje cells in the cerebellar cortex. Here we show that T3 promotes dendritic outgrowth of Purkinje cells through induction of peroxisome proliferator-activated receptor gamma (PP...
