This p53‐mediated miR‐34a expression was demonstrated to be involved in cell apoptosis of cancer cells.13 In addition, several predicted miR‐34a targets, including cyclin D1, CDK6 and c‐Met 10, 12 which participate in cell growth control, have been confirmed to be transcriptionally regulated by miR‐34a and their down‐regulations through miR‐34a did suppress cancer cell progression. The gene discussed is MET; the disease is cancer.
