Hypoxia, the state of reduced oxygen partial pressure and energy supply, is one of the key factors to initiate angiogenesis. The formation of new blood vessels is a major factor that governs the development and progression of numerous malignancies.
Accumulating data indicated that intracellular signal transduction modulates angiogenesis in hypoxic cells. The aim of this study was to investigate the molecular mechanisms involved in hypoxia-induced angiogenesis and to determine if PI3K/Akt or Bcl-2 are involved in this process. HUVEC cells were cultured in vitro under normoxic and hypoxic conditions, and the phosphorylation of Akt, expression of Akt and Bcl-2 protein were examined. The activity of PI3K/Akt was assessed by Western blot. We found that hypoxia could remarkably induce Akt phosphorylation in HUVEC cells. Interestingly, in hypoxia, there was an increase in the expression of Bcl-2 protein, which was blocked by PI3K inhibitor wortmannin and transfection with siRNA. In conclusion, we have found that hypoxia could increase Ĭorporate Netsuite get in touch with with the billing manager on the domain administrator section to begin.
