Core Tip
Core Tip: Endothelial cell-derived vasohibin 1 (VASH1) can regulate tumor angiogenesis and lymphangiogenesis, and tumor cell-derived VASH1 also has a potential functional role in inhibiting cancer cell proliferation and invasion. Knockdown of VASH1 enhanced transforming growth factor beta 1 (TGF-β)/Smad3 pathway activity and type I/III collagen production. Our previous findings suggest that ELL-associated factor 2 (EAF2) may play a tumor suppressor and protective role in the development and progression of colorectal cancer (CRC) by regulating signal transducer and activator of transcription 3 (STAT3)/TGF-β1 signaling pathway. In this study, we found that EAF2 was down-regulated and VASH1 was up-regulated in advanced CRC tissue compared to normal colorectal tissue by immunohistochemistry and Western blot. And the expression levels of EAF2 and VASH1 were positively correlated in advanced CRC tissue. Furthermore, in vitro cellular mechanism studies suggest that overexpression of EAF2 may inhibit the activity of STAT3/TGF-β1 pathway by up-regulating the expression of VASH1, thereby attenuating the invasion, migration and angiogenesis of CRC cells. This study provides new ideas and theoretical basis for the development of new diagnostic markers for CRC and the exploration of the mechanism of targeted therapy.
