PPP1R1B and colorectal carcinoma: The percentage of MTX‐resistant CRC cells arrested in the G0 phase in the miR‐760 mimic group and the si‐PPP1R1B group was notably higher than that in the NC group, suggesting that miR‐760 overexpression and PPP1R1B knockdown induce G0 cell cycle arrest in MTX‐resistant CRC cells.
