Fig. 3. Effects of indicator materials (costunolide [CO] and dehydrocostus lactone [DCL]) on the mRNA levels of the apoptosis-related gene BCL-2 in prostate tissues. The mRNA expression levels of the apoptosis-related gene BCL2 in prostate tissues were measured by real-time polymerase chain reaction. Values are expressed as mean±standard error of the mean (n=6). ^ap<0.05 compared to the benign prostate hyperplasia (BPH) group. Statistical analyses were performed by ANOVA and Dunnett's multiple comparison test.
