TP53 and neoplasm: Likewise, p53 (green node), a tumor suppressor is also post-transcriptionally regulated by several miRNAs such as miR-25 and miR-30d in myeloma cells [108], miR-125a in breast and hepatoblastoma cells [109], miR-125b in neuroblastoma and lung fibroblalst cells [110], miR-504 in breast and colon cancer cells [111], miR-1285 in neuroblastoma, hepatoblastoma and breast cancer cells [112], miR-33 in hematopoietic stem cells [113] and miR-380 in neuroblastoma cells [114].
