Effect of germacrone on the expression of mitochondria apoptosis-regulatory proteins Bax and Bcl-xL. Total proteins were prepared after BGC823 cells were treated with germacrone at different concentreations (0, 20, 40, 60, and 80 μM) and then analyzed by western blotting. a Representative blotting bend intensities used for the quantification of Bax and Bcl-xL. b Quantitative data of the Bax/Bcl-xL ratio from protein expression. β-actin was used as an internal control. “*”: P < 0.05, “**”: P < 0.01
