Aspirin inhibits the proliferation of some CCA cells. All cell lines were treated with 0, 2.5, 5, or 10 mmol/l aspirin for 24 or 48 h. The data points represent the mean cell number from three independent cultures, and the error bars represent standard deviations. The antiproliferative effect was significantly higher in cells treated with aspirin treatment for 48 h than in control cells (0 mmol/l) as determined by two-way analysis of variance, except for TKKK cells. ^*P<0.01, vs. the control. CCA, cholangiocarcinoma.
