Repression of miRNAs by MYC, including tumor suppressor miRNAs like miR-29 and miR-34a, has been shown to contribute to cellular survival by activating anti-apoptotic proteins such as CCND1 and BCL2. But also MYC-induced activation of miRNAs has been shown to promote cell cycle progression39. This evidence concerns the gene CCND1 and neoplasm.
