Diabetes risk increases significantly with age and correlates with lower oxidative capacity in muscle. Decreased expression of peroxisome proliferator-activated receptor-γ coactivator-1α (Pgc-1α) and target gene pathways involved in mitochondrial oxidative phosphorylation are associated with muscle insulin resistance, but a causative role has not been established. We sought to determine whether...
Activation of AMP-activated kinase (AMPK) in skeletal muscle increases glucose uptake, fatty acid oxidation, and mitochondrial biogenesis by increasing gene expression in these pathways. However, the transcriptional components that are directly targeted by AMPK are still elusive. The peroxisome-proliferator-activated receptor gamma coactivator 1alpha (PGC-1alpha) has emerged as a master regulat...
Underexpression of the transcriptional coactivator PGC-1α is causally linked to certain neurodegenerative disorders, including Huntington's Disease (HD). HD pathoprogression is also associated with aberrant NMDAR activity, in particular an imbalance between synaptic versus extrasynaptic (NMDAR(EX)) activity. Here we show that PGC-1α controls NMDAR(EX) activity in neurons and that its suppressio...
The transcriptional coactivator PPARγ coactivator-1α (PGC-1α) is a critical regulator of mitochondrial content and function in skeletal muscle. PGC-1α may also mediate mitochondrial adaptations in response to chronic contractile activity (CCA). To characterize the essential role of PGC-1α in organelle biogenesis, C₂C₁₂ murine myotubes were transfected with PGC-1α-specific siRNA and subjected to...
Peroxisome proliferator-activated receptor γ coactivator-1α (PGC-1α) is a transcriptional coactivator of nuclear receptor peroxisome proliferator-activated receptor γ that critically regulates glucose and fat metabolism. Although clinical evidence suggests that Gly482Ser polymorphism of PGC-1α is associated with an increased incidence of nonalcoholic fatty liver disease, a direct role for Gly48...
Background: Obesity is associated with increased risk of many diseases. Methylation is an important factor in obesity, indicating epigenetic changes. However, there is lack of data about PGC-1α methylation and regular exercise. Purpose of this study was to determine effects of 6-week high-intensity interval training (HIIT) on PGC-1α methylation in gastrocnemius muscle of obese male rats. Metho...
Introduction: PGC-1α gene plays an important role in regulating cellular energy metabolism and stimulating the increased cell mitochondrial mass. Understanding the status of this gene polymorphism in non-athletic male adolescents may be helpful in choosing and identifying the sport talented male adolescents. The purpose of the present study was to investigate possible association between PGC-1α...
Perennial groundcover (PGC) merges scalable soil and water conservation with high-yielding row crops, enhancing ecosystem services of annual grain crop production. However, ineffective suppression increases competition between the crop, reducing yield. The objective this study was to assess effectiveness three Kentucky bluegrass (KBG) methods each at narrow wide widths on maize (Zea mays L.) gr...
چکیده سابقه و هدف: تغییر در فعالیت و محتوای pgc-1α احتمالاً به دلیل پلی مورفیسم های آن اثرات گسترده ای برروی فرایندهای متابولیک در افراد مبتلا به دیابت نوع 2 (t2d) دارد. نتایج متفاوت و متناقضی در مورد ارتباط پلی مورفیسم rs2970847 ژن pgc-1α و t2d گزارش شده است. این مطالعه با هدف تعیین ارتباط پلی مورفیسم thr394thr ژنpgc-1α و t2d به روش مروری و متاآنالیز انجام گرفت. روش بررسی: این مرور سیستماتیک به...
BACKGROUND Pepsinogen C (PGC) and mucin1 (MUC1) are important physiologically functional gastric proteins; Mucin2 (MUC2) is an "ectopic" functional protein in intestinal metaplasia of gastric mucosa. We analyzed the co-expression of the above-mentioned three proteins in dynamic gastric diseases {superficial gastritis (SG)-atrophic gastritis (AG)--gastric cancer (GC)} as well as different histol...
