Contractile properties of cardiomyocytes from FVB mice incubated for 2 hrs with the oxidative stress inducer menadione (30 μM) in the absence or presence of the antioxidant N-acetylcysteine (NAC, 500 μM) or the ER stress inhibitor tauroursodeoxycholic acid (TUDCA, 500 μM). Panel A: resting cell length; Panel B: Peak shortening (normalized to cell length); Panel C: Maximal velocity of shortening (+ dL/dt); Panel D: Maximal velocity of relengthening (− dL/dt); Panel E: Time-to-PS (TPS); and Panel F: Time-to-90% relengthening (TR90). Mean ± SEM, n = 43 – 49 cells from 3 mice per group, * p < 0.05 vs. control group, # p < 0.05 vs. menadione group.
