Cell cycle, proliferation, apoptosis and invasion are among the cellular processes that miR-145, as a potent tumor suppressor, regulates, whereas p53 has been shown to induce miR-145 levels, which, in turn, inhibits MYC and MUC1 (mucin 1 cell surface-associated protein) [182,183]. The gene discussed is MUC1; the disease is neoplasm.
