Research Abstract |
Invasive phenotype was induced by inhibition of VEGF signaling. Hypoxia inducible factor(HIF) is a transcription factor, which regulate hypoxic response. We generated double KO mice of HIF-1αand VEGF in islet cell tumor model mice. Invasive phenotype was remarkably reduced in DKO mice. Levels of E-cadherin expression was reduced in VEGF KO tumors but recovered in DKO mice. Thus, HIF is important for invasive phenotype after angiogenesis inhibition, and decreased E-cadherin levels might be a downstream mechanism.
