MG53 inhibits cellular proliferation and tumor progression in colorectal carcinoma.

ABSTRACT: Cancer is the second leading cause of mortality after cardiovascular diseases in the United States. Chemotherapy is widely used to treat cancers. Since the development of drug resistance is a major contributor towards the failure of chemotherapeutic regimens, efforts have been made to develop novel inhibitors that can combat drug resistance and sensitize cancer cells to chemotherapy. Here we investigated the anti-cancer effects of MG53, a TRIM-family protein known for its membrane repair functions. We found that rhMG53 reduced cellular proliferation of both parental and ABCB1 overexpressing colorectal carcinoma cells. Exogenous rhMG53 protein entered SW620 and SW620/AD300 cells without altering the expression of ABCB1 protein. In a mouse SW620/AD300 xenograft model, the combination of rhMG
