Antitumor effects of umbelliprenin in a mouse model of colorectal cancer

Abstract

Umbelliprenin is a sesquiterpene coumarin with vitro anti-carcinogenic activities. The aim of this study was to investigate the antitumor effects of umbelliprenin in animal models of colorectal cancer. The cytotoxic effects of umbelliprenin were explored on CT26 and L929by MTT assay. In this study, colorectal tumors developed in mice by intradermal injection of CT26 cell line. Tumor size, serum levels of IFN-γ and IL-4 by ELISA, and Ki-67, MMP2, MMP9, VEGF and E-cadherin markers by IHC method were evaluated. The results showed that umbelliprenin inhibited the cancer cells in a concentration-dependent manner. IC50 Evaluation showed that L929 cells were more resistant to Umbelliprenin than CT26 cells. Umbelliprenin treatment in both tumor-bearing mice and control normal mice showed significantly increased IFN-γ and decreased IL-4(P
