Hypoxia-induced up-regulation of VASP promotes invasiveness and metastasis of hepatocellular carcinoma

Abstract

A variety of hypoxia-induced molecular mechanisms contributed to the upregulation of VASP at transcriptional and post-transcriptional levels. These mechanisms involved CRKL, HIF-1α, miR-204, and TGF-β activating the AKT and ERK signaling to promote EMT and expression of MMPs. Taken together, our results defined VASP as an oncogene of HCC pathogenesis and metastasis with the potential to serve as a prognostic biomarker.
