ABSTRACT
Aim To probe into the bavachinin toxic mechanisms in HepaRG cells. Methods MTT assay was used to determine toxicity and dose. After treated with 6.25,12.5 and 25 μmol·L-1bavachinin for 24 h,the cell death was investigated by Hoechst 33342/PI,LDH,caspase-3 activity,and Bax,Bcl-2 expression levels. Mitochondrial damage was detected by mito-chondrial membrane potential,ATP content,openness of mitochondrial permeability transition pore and cyto-chrome C level. Results Bavachinin administration up-regulated Bax/Bcl-2 ratio and caspase-3 activity with increase of drug concentration after 24 h. Apop-totic rate increased in a dose-dependent manner be-tween 6.25 and 25 μmol·L-1,but when reached to 25 μmol·L-1,cells showed more necrosis. Mitochon-drial injury indicators significantly increased after 24h. Conclusion Bavachinin induces HepaRG cell apopto-sis and necrosis through mitochondria injury.
