The HRG-β1-induced expressions of Snail, vimentin, and fibronectin, and nuclear colocalization of phospho-Smad2 and Snail were inhibited by pretreatment with a PI3k inhibitor, LY294002, or two phospho-Smad2 inhibitors, PD169316 or SB203580 and cancer cell migration by HRG-β1 was inhibited. Here, VIM is linked to cancer.
