Figure 1. TXNIP is highly expressed in the rat model of I/R. (A) The preoperative, intraoperative and postoperative ST segments (mV) in sham-operated rats (n = 12) (left) and in rats with I/R (n = 72) (right); * p < 0.05 vs. the preoperative ST segment; # p < 0.05 vs. the intraoperative ST segment. (B) TXNIP expression in myocardium determined by RT-qPCR; * p < 0.05 vs. the sham group (sham-operated rats). (C) TXNIP protein expression in myocardium normalized to GAPDH determined by Western blot analysis; * p < 0.05 vs. the sham group (sham-operated rats). (D) The positive expression of TXNIP in myocardium identified by immunohistochemistry (400 ×); * p < 0.05 vs. the sham group (sham-operated rats). Measurement data were presented as mean ± standard deviation. Comparison between two groups was analyzed by unpaired t-test. Comparison among multiple groups was analyzed by one-way analysis of variance, followed by Tukey’s post hoc test. n = 12.
