CRCs were transfected with miR-4780 mimic, miR-4780 mimic NC, miR-3938 inhibitor, miR-3938 inhibitor NC using siRNA and siRNA-MateTM transfection reagent (ribo FECT ™ CP Transfection Kit). Briefly, 50–100 nM siRNA and 5ug/mL polybrene were mixed together and then added to cells that were 50–60% confluent. At 24–36 h after transfection, cells were collected for subsequent experiments.
