Representative Western blots of apoptosis-associated protein samples extracts from the left atrium.

(A) Examples of the western blot bands recognized by the caspase-3 antibodies (36 kDa) for sham-operated, CRAP and CRAP+RSD groups. (B) Western blots for Bcl-2 with a specific band at 26 kDa were performed for sham-operated, CRAP and CRAP+RSD groups. (C) A specific band at 21 kDa for bax was detected in left atrial tissue of sham-operated, CRAP and CRAP+RSD groups. Antibodies for β-actin with a specific band at 43 kDa were used as reference. Bcl-2, B-cell Lymphoma Gene 2. *P<0.05, **P<0.01 vs sham-operated group; ^#P<0.05, ^##P<0.01 vs CRAP group.
