miR-124 acts as a tumor suppressor gene in medulloblastoma pathogenesis by inhibiting cell cycle progression in the G0/G1 phase without affecting apoptosis, slows down tumor growth by targeting CDK6 proto-oncogene, and inhibits cell proliferation in DAOY and D283 cells and solute carrier family 16 (SLC16A1) [32]. The gene discussed is CDK6; the disease is neoplasm.
