Hepatocellular carcinoma (HCC) is a highly vascularized tumor with frequent extrahepatic metastasis. Active angiogenesis and metastasis are responsible for rapid recurrence and poor survival of HCC. However, the mechanisms that contribute to tumor metastasis remain unclear. Here we evaluate the effects of ATPase inhibitory factor 1 (IF1), an inhibitor of the mitochondrial H(+)‐adenosine triphosphate...
Objective To investigate the effect of siRNA against PTP-1B on neonatal rat cardiac myocyte apoptosis induced by hypoxia-reoxygenation (H/R) and its molecular mechanisms. Methods Isolated neonatal and adult rat cardiac myocytes were cultured for 24 h after PTP-1B siRNA transfection, and with 2, 4 and 6 h of hypoxia followed by 6 h of reoxygenation (H/R). The cardiac myocyte apoptosis induced by...
