Core Tip

Core tip: To assess the clinicopathologic and biological significance of cripto as a novel target for colon cancer gene therapy, pathological and in vitro studies were carried out. Cripto was significantly overexpressed in primary colon cancer and metastatic lymph nodes. In vitro studies found that cripto siRNA resulted in a significant reduction in colony formation in soft agar and in the migration and invasion abilities of colon cancer cells. Furthermore, cripto siRNA led to an inhibition of MMP-7 and MMP-9. These results suggest that the cripto gene be useful for devising novel preventive and therapeutic strategies for colon cancer.
