Quantitative RT-PCR for expression of cytochrome c (CYCS), caspase 9 (CASP 9), caspase 3 (CASP 3), and caspase 7 (CASP 7), and the relative intensities and Western blot images of the indicated heat shock proteins (HSPs) in the Hanwoo Longissimus thoracis muscle at 24 h post-mortem for groups categorized by Warner-Bratzler shear force (WBS) values. Gels stained by Coomassie blue were used as protein loading controls. Bars indicate the standard error of the mean. ^a,b Different letters denote significant differences (p < 0.05).
