CADM1 and leukemia: Some rescue experiments were conducted by transfecting in-NC + si-NC, in-miR-1246 + si-NC, or in-miR-1246 + si-CADM1 into chemo-resistant leukemia cells to illuminate whether CADM1 participated in the process of miR-1246 playing its biological function in chemotherapy-resistant leukemia cells.
