In order to evaluate the effect of DCLK3 on the biological functions of miR-1236-3p in colon cancer cells, the SW620 cells were co-transfected with the miR-1236-3p mimic, mimic control, miR-1236-3p inhibitor and inhibitor control, after overexpression or knockdown of DCLK3. Here, DCLK3 is linked to malignant colon neoplasm.
