Celexoxib or aspirin treatment had no effect on body weight and liver weight. Mice were inoculated with MCF-7aro cells and treated with celecoxib, aspirin and androstenedione. Their body weight (A) was monitored from the second week after inoculation and liver weight (B) was measured at the end of experiment. Groups labeled as AD, AD+celecoxib, and AD+aspirin are the mice treated with androstenedione, androstenedione and celecoxib, and androstenedione and aspirin, respectively. Values are means ± SEMs, n=6 to 8. The data was analyzed by One-way ANOVA, followed by Tukey’s Multiple Comparison test when P<0.05.
