These results demonstrate that notall cells harboring Bax G7 mutations are able to generate BaxΔ2 proteins.Analysis of human buccal cells could provide a sensitive and non-invasive screeningof Bax microsatellite status and BaxΔ2 protein expression with potentialclinical applications in the treatment of MSI colon cancer patients. Here, BAX is linked to malignant colon neoplasm.
