Fig. 4. ZNF281 knockdown inhibits the proliferative ability of CRC cells in vitro. (A) Effects of sh-ZNF281 and vector on cell proliferation were determined by CCK8 cell proliferation assay. (B) Cell cycle G1 arrest after ZNF281 knockdown was measured by flow cytometry. Mean ± SEM, t-test, *P<0.05, **P<0.01.
