Olaparib does not protect cardiac myoblasts against prolonged, low‐level oxidative stress at later time points. (A) Experimental design. (B) Reduction of MTT and release of LDH in H9c2 cells treated with 0.05 U·mL⁻¹ GOx for 1 h followed by washout of GOx and incubated for additional 24 h in the absence or presence of 10 μM olaparib (olap). (C) Western blot analysis of PARylation and PARP1 (* indicates non‐specific band). Data shown are means ± SEM. n = 5 per group.
