MCL1 and neoplasm: MiR-125 family is highly conserved throughout evolution, and it was demonstrated to regulate tumorigenesis and tumor development by targeting important genes including transcription factors like CBFB and TGF-β [52, 53], anti-apoptotic genes like BCL2, BCL2L12 and Mcl-1 [54], pro-apoptotic protein Bak1 [55], and tumor suppressing protein p53 [55, 56].
