摘要
Background and Puepose: The molecular pathological markers of vascular endothelial growth factor (VEGF), hypoxia inducible factor-1 alpha (HIF-1α), von Hippel-Lindau tumor suppressor protein (VHL) and peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC- 1α), are recently linked in the regulation of oxygen availability. The purpose of this study was to investigate these molecular markers of the cardiomyocyte adapt to moderate endurance training. Materials and Methods: we performed immunohistochemical staining coupled with image analysis for quantification in male Sprague- Dawley rat myocardium that had been trained on treadmill running at 20 m/min for 30 min on a 0% grade, for 3 days/wk. for 4 weeks (4WT) or 8 weeks (8WT) and control rats for 4 weeks (4WC) or 8 weeks (8WC) (n=6, respectively). Results: Training led to no significant alteration in HIF-1α content. Interestingly, a lower VHL content and higher VEGF contents were detected in the trained groups compared with their control counterparts (p
