Abstract
Although angiogenesis is crucial for tumor growth and metastasis, the molecular mechanisms controlling this process are not clearly understood. Here, we explore the role of Dab2 in tumor angiogenesis. We found that Dab2 is expressed in several cancer cells, including A549 lung cancer cells, but it is hardly detectable in SW480 colon cancer cells. Migration and Erk phosphorylation were enhanced in human umbilical vein endothelial cells (HUVECs) treated with the conditioned medium obtained from Dab2-overexpressing SW480 stable cells. In addition, vascular endothelial growth factor (VEGF) protein was strongly detected in conditioned medium derived from Dab2-overexpressing SW480 cells, and Erk phosphorylation enhanced by Dab2(+) CM was restored by VEGF inhibition. Moreover, Dab2 depletion in A549 cells led to a decrease in HUVEC migration and Erk phosphorylation. Furthermore, we show that Dab2 is required for the TGF beta-induced gene expression of angiogenic factors such as VEGF and FGF2. Taken together, these results suggest that Dab2, which is expressed in cancer cells, is pivotal for endothelial cell migration by affecting VEGF expression. (C) 2012 Elsevier Inc.
