Abstract

We have recently reported that astrocyte elevated gene-1 (AEG-1) might be an epithelial–mesenchymal transition (EMT) associated biomarker in human hepatocellular carcinoma (HCC), and play an important role in the progression of hepatocellular carcinoma. To extend our study, we examined here the anti-invasive and metastatic effects of Huaier polysaccharide (HP) on human HCC cell line MHCC97-H and explored its possible mechanism of action. Treatment with HP dose-dependently inhibited the proliferation, adhesion, migration and invasion of MHCC97-H cells in vitro. This was achieved not only by reducing the expression of AEG-1 and N-cadherin, but also by enhancing E-cadherin expression. Therefore, these data suggested that HP can inhibit the growth and metastatic potential of MHCC97-H cells through modulation of the AEG-1/EMT pathway.
