Effects of Sev preconditioning on linc0278/miR-134-5p-regulated HR myocyte injury and oxidative stress levels. A-C Expression of cardiomyocyte injury markers cTnI, CK-MB, and LDH in Sev-preconditioned HR myocytes under normal conditions, after silencing of linc01278, and after concomitant use of miR-134-5p inhibitor. (A) cTnl. (B) CK-MB. (C) LDH. D-F The levels of oxidative stress markers MDA, SOD and GSH-Px in cardiomyocytes co-regulated by miR-134-5p and linc01278 were measured in Sev-treated H/R cells. (D) MDA. (E) SOD. (F) GSH-Px. * P < 0.05, ** P < 0.01, *** P < 0.001, **** P < 0.0001
