Scientists from the Institute for Basic Science (IBS) have successfully inhibited the growth of colon tumors in mice with mismatch repair deficiency. The research team, headed by the Center's director MYUNG Kyungjae, made the announcement in a manuscript published in the American Association for Cancer Research on June 6th. It is a significant breakthrough for the future treatment of colon cancer patients; specifically for those with DNA mismatch repair (MMR) deficient tumors.
