Figure 1. LncRNA AK020546 was downregulated in H9c2 cardiomyocytes and myocardium subjected to H2O2 treatment and I/R injury. (A) The expression of lncRNA AK020546 in H9c2 cardiomyocytes at different time points after H2O2 treatment was detected with qPCR (n = 5). (B) The expression of lncRNA AK020546 in the myocardium at different time points of reperfusion was evaluated by qPCR (n = 5). *p < 0.05 vs oh or sham group.
