CHD5 inhibits growth of gastric cancer cell line AGS. The effect of ectopic CHD5 expression on tumor cell growth was investigated by the monolayer colony formation assay. A, CHD5 expression in AGS cells after transfection was determined by RT-PCR. The photograph of colonies formed by AGS cells transfected with pcDNA3.1 (vector) or pcDNA3.1-CHD5 (CHD5) was shown in B. C, Quantitative analyses of colony numbers are shown as values of mean ± standard deviation. P values were calculated using student's t-test. The asterisk indicates statistical significant difference (p < 0.01).
