Abstract

Angiogenesis is an essential requirement for the development, progression and metastasis of malignant tumors. Vascular endothelial growth factor (VEGF) plays an essential role in the development of angiogenesis of numerous solid malignancies, including colon cancer. The tumor suppressor gene p53 is a potent transcriptional regulator of genes which are involved in many cellular activities, including cell-cycle arrest, apoptosis and angiogenesis. In order to better understand the relation among p53 status, VEGF expression and microvessels count (MVC) in colon cancer, we evaluated immunoreactivity for CD34 endothelium-associated antigen, VEGF and p53 proteins in 43 cases of colon adenocarcinoma. Our results demonstrated an association between VEGF expression, p53 status and angiogenesis, suggesting that mutant p53 plays a central role in promoting angiogenesis in colon cancer progression.
