Abstract
Hepatocellular carcinoma (HCC) is a malignant tumor with high morbidity and mortality, and is characterized by high potential for metastasis and recurrence. The outcome of it is still poor due to lacking of targeted therapeutic strategies. There is an urgent need to find new therapeutic targets for interventions against HCC metastasis and recurrence. In the present study, we found cytohesin-3, a member of the cytohesin family, was upregulated in HCC tissues, and its expression was negatively correlated with the overall survival and relapse-free survival of HCC patients. Further clinicopathological correlation analysis revealed that cytohesin-3 expression was related with tumor size and vascular invasion. And in vitro studies revealed that knock-down of cytohesin-3 suppressed HCC cells proliferation and migration. These results suggest that cytohesin-3 may act as a novel prognostic factor of HCC, and it might also be useful to exploit targeted therapeutic drugs against HCC growth and metastasis.
