Moreover, loss of MIR129 expression by MIR129-2 methylation has been reported in gastric, endometrial, and colorectal cancers [8-10], leading to upregulation of oncogenes including cyclin-dependent kinase 6 (CDK6) and sex determining region Y-box 4 (SOX4) mRNAs, thereby illustrating the tumor suppressive effect of MIR129[9-12]. This evidence concerns the gene CDK6 and neoplasm.
