Further immunohistochemical and western blot analysis showed that after miR-107 mock treatment, the expression of miR-107 in tumors was significantly increased, while the expression of TRIAP was significantly decreased, the expression of tumor growth marker Ki67 was significantly decreased, and the expression of apoptosis-related proteins was significantly (Bad, CCS-3) increased, suggesting that miR-107 could inhibit tumor progression in mice (Figures 6C–F). The gene discussed is MKI67; the disease is neoplasm.
