The relative amounts of protein expression levels of molecular markers associated with apoptosis, such as caspase-3, Bcl-2 and Bax. (a) Results of Western blotting of caspase-3, Bcl-2, Bax and glyceraldehyde-3-phosphate dehydrogenase (GAPDH). (b) The statistical analysis graph of relative expression levels of these markers normalized to that of GAPDH. Hypoxia for 8 hours and reoxygenation for 16 hours (hypoxia/reoxygenation [H/R]) up-regulated the expressions of caspase-3 and Bax, and down-regulated Bcl-2 expression. calreticulin overexpression induced by plasmid transfection 24 h before H/R further aggravated the changes induced by H/R, while siRNA interference and taurine administration had the opposite effects. Each experiment was repeated in triplicate (*P < 0.05 vs. control. †P <0.05 vs. H/R).
