The transcriptional coactivator peroxisome proliferator-activated receptor γ coactivator 1α (PGC-1α) regulates expression of genes for metabolism and muscle fiber type. Recently, a novel splice variant of PGC-1α (NT-PGC-1α, amino acids 1-270) was cloned and found to be expressed in muscle. Here we use Flag-tagged NT-PGC-1α to examine the subcellular localization and regulation of NT-PGC-1α in s...
The aim of this study was to test whether the transcriptional coactivator peroxisome proliferator-activated receptor (PPAR)-γ coactivator (PGC)1α regulates the content of pyruvate dehydrogenase (PDH)-E1α and influences PDH activity through regulation of pyruvate dehydrogenase kinase-4 (PDK4) expression and subsequently PDH phosphorylation. PGC-1α whole body knockout (KO), muscle-specific PGC-1α...
Abstract Background: PGC-1α is involved in the regulation of several metabolic processes and its reduced expression has been observed in early stages of type 2 diabetes, (T2D). Changes in activity of PGC-1α, probably due to its polymorphisms, have extensive effects on metabolic processes in people with T2D. The association of rs2970847 polymorphism of PGC-1α gene with T2D has been investigat...
Accumulating evidence shows that peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α) is involved in the progression of hormone-related cancers, and there may exist an association between estrogen and PGC-1α. Notably, emerging evidence has led to considerable interest in the role of PGC-1α in endometrial cancer development. However, whether the synergism exists between PGC-1...
Peroxisome proliferator-activated receptor γ coactivator-1α (PGC‑1α), a coactivator interacting with multiple transcription factors, regulates several metabolic processes. Although recent studies have focused on the role of PGC‑1α in cancer, the underlying molecular mechanism has not been clarified. Therefore, we evaluated the role of PGC‑1α in cell proliferation and tumorigenesis using human e...
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...
The transcriptional coactivator peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) is a key determinant of cardiac metabolic function by regulating genes governing fatty acid oxidation and mitochondrial biogenesis. PGC-1α expression is reduced in many cardiac diseases, and gene deletion of PGC-1α results in impaired cardiomyocyte metabolism and function. Reduced fuel supply ge...
Regular endurance exercise remodels skeletal muscle, largely through the peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α). PGC-1α promotes fiber type switching and resistance to fatigue. Intracellular calcium levels might play a role in both adaptive phenomena, yet a role for PGC-1α in the adaptation of calcium handling in skeletal muscle remains unknown. Using mice with tra...
Muscle wasting associated with chronic diseases has been linked to decreased expression of PGC-1α and overexpression of PGC-1α counters muscle loss. CREB, in conjunction with the CREB-regulated transcription coactivator (CRTC2), is a positive modulator of PGC-1α transcription. We previously reported that PGC-1α expression is decreased in skeletal muscle of diabetic rats despite a high level of ...
