Fig. 1From: Atherogenic L5 LDL induces cardiomyocyte apoptosis and inhibits KATP channels through CaMKII activationIncreased apoptosis and decreased cell viability in NRCMs treated with L5. a, Early apoptosis of NRCMs treated with L5, shown by representative images of Hoechst (blue, nuclei), Annexin V-Alexa 488 (green), and PI (red) staining. b, Dose-dependent curve showing the effects of increasing concentrations of L5 and L1 on the percentage of cells staining positive for Annexin V (n = 6 per group). c, Relative apoptosis levels of NRCMs after the indicated treatment, determined by using a caspase-3/7 activity assay (n = 7 per group). d, Cardiomyocyte viability was analyzed after the indicated treatment by using an MTT kit, n = 6 per group. *P < 0.05, **P < 0.01 vs. the PBS-treated groupBack to article page
