Effect of nicotine (2 mg/kg/d for 10 days, i.p.) on intracellular Ca2+ property in cardiomyocytes from FVB and MT mice. Panel A: Baseline fura-2 fluorescence intensity (FFI); Panel B: Change in FFI (ΔFFI) in response to electrical stimuli; Panel C: Single exponential fluorescence decay rate; and Panel D: Bi-exponential fluorescence decay rate. Mean ± SEM, n = 81 - 84 cells per group, *p < 0.05 vs. FVB group, # p < 0.05 vs. FVB+NIC group.
