Cohn et al. compared the expression of miRNAs between MMR-intact and MMR-deficient endometrial carcinomas of endometrioid subtype, and found six miRNAs (mir-29a, -126, -1-2, -143, -125b, and -133) that had at least a twofold reduction in expression [28]. Here, MRC1 is linked to endometrial carcinoma.
