To date, a cohort of genes related to different cancer pathways have been identified and validated as targeted genes of miR-145, such as Pai-1, Fascin1, Oct-4, Sox-2, Klf4, c-Myc, IRS1, Muc1, Yes, Stat1, and p70S6K1[18-25], suggesting that miR-145 is an oncosuppressor and plays an important role in the initiation and progression of tumor, as supported by several direct evidences that the ectopic expression of miR-145 in cancer cells leads to a loss in cell viability and induces cell death [13,19,26]. The gene discussed is YES1; the disease is cancer.
