siRNA Targeting Net1 Reduces the Angiogenesis and Tumor Growth of in vivo Cervical Squamous Cell Carcinoma through VEGF down-regulation

Net1, a guanine nucleotide exchange factor, is implicated in cancer cell invasion through activation of RhoA. However, there is still no report on the association between Net1 and cancer angiogenesis. The current study was designed to explore the roles of Net1 in the angiogenesis of cervical squamous cell carcinoma (CSCC) and further observe the effects of Net1 siRNA on the tumor growth. Net1 was overexpressed in CSCC samples (n=80), correlated to the cancer microvessel density (MVD, r=0.223, P=.026) and related to aggressive clinical behaviors, including depth of cervical wall invasion (P=.041), parametrial involvement (P=.037), lymph node metastasis (P=.021) and vascular invasion (P=.018).
