This study was undertaken to investigate the effect of phosphodiesterase-5 (PDE5) inhibitor, sildenafil, on angiogenic response in human coronary arteriolar endothelial cells (HCAEC). The cells exposed to sildenafil (1–20 μM) demonstrated significantly accelerated tubular morphogenesis with the induction of thioredoxin-1 (Trx-1), hemeoxygenase-1 (HO-1) and VEGF. Sildenafil induced VEGF and angiopoietin...
Existing evidence indicates that resveratrol, a red wine and grape-derived polyphenolic antioxidant, can pharmacologically precondition the heart in a nitric oxide (NO)-dependent manner. To further explore the role of NO in resveratrol-mediated cardioprotection, the induction for the expression of the potential molecular targets of NO including VEGF and KDR as well as iNOS and eNOS were examined by...
