Trx2 reduces the apoptosis ofcardiomyocytes in I/R rat myocardia. (A) Representative TUNEL staining images (original magnification, x400). (B) Quantification of the mean apoptotic index (AI) in each group. (C) Western blotting analysis of cleaved caspase 3, Bcl-2, Bax and ASK1. (D) Quantitation of (C) as fold change by normalizing to control (arbitrarily set as 1.0). β-actin was used as an internal control. *p < 0.05 vs. SO group, #p < 0.05 vs. I/RorLv-GFP-N group, @p>0.05 vs. I/R group.
