RESUMEN

Objective To evaluate the expressions of hypoxia-inducible factor-1α(HIF-1α),vescular endothelial growth factor(VEGF)and survivin in developing colorectal cancer,and the association among them.Methods The protein expressions of HIF-1α,VEGF and survivin were detected in specimens obtained from 69 patients with colorectal cancer and 20 normal controls by immunohistochemistry.The correlations of HIF-1α,VEGF and survivin with clinicopathologic features were analyzed.Results The expression of HIF-1α,VEGF and survivin proteins in patients with colorectal cancer were 56.52%,66.67% and 46.38%,respectively,and little expressed in normal controls(P<0.01).The expressions of HIF-1α,VEGF and survivin were closely related to the differential grade of adenocarcinoma,he in volvment of penetration,lymph node metastasis and Dukes stage(P<0.05).In addition,HIF-1α protein expression had positive correlations with both VEGF and survivin(P<0.05),and the expression ofVEGF also had positive correlation with survivin(P<0.05).Conclusions HIF-1α may involve in thepathogenesis of colorectal cancer through up regulating the expressions of VEGF and survivin,which mayhave synergetic effects in the pathogenesis of colorectal cancer.
