NDRG1 and colorectal carcinoma: Cell cycle analysis indicated that there was clearly more G0/G1 phase cell population in the NDRG1 overexpression group in compared to the relative control group (60.70% vs. 46.23% in HCT116 and 55.48% vs. 40.71% in SW1116), suggesting that NDRG1 could induce G0/G1 arrest in CRC cell lines.
