	1	Effects of PGC-1αoverexpression on the myogenic response during skeletal muscle regeneration显示文摘The ability of skeletal muscle to regenerate from injury is crucial for locomotion,metabolic health,and quality of life.Peroxisome proliferator-activated receptor-γcoactivator-1α(PGC1A)is a transcriptional coactivator required for mitochondrial biogenesis.Increased mitochondrial biogenesis is associated with improved muscle cell differentiation,however PGC1A's role in skeletal muscle regeneration following damage requires further investigation.The purpose of this study was to investigate the role of skeletal muscle-specific PGC1A overexpression during regeneration following damage.22 C57BL/6J(WT)and 26 PGC1A muscle transgenic(A1)mice were injected with either phosphate-buffered saline(PBS,uninjured control)or Bupivacaine(MAR,injured)into their tibialis anterior(TA)muscle to induce skeletal muscle damage.TA muscles were extracted 3-or 28-days postinjury and analyzed for markers of regenerative myogenesis and protein turnover.Pgc1a mRNA was~10–20 fold greater in A1 mice.Markers of protein synthesis,AKT and 4EBP1,displayed decreases in A1 mice compared to WT at both timepoints indicating a decreased protein synthetic response.Myod mRNA was~75%lower compared to WT 3 days post-injection.WT mice exhibited decreased cross-sectional area of the TA muscle at 28 days post-injection with bupivacaine compared to all other groups.PGC1A overexpression modifies the myogenic response during regeneration.
