Fig. 8From: Differences in the Expression of Heat-Shock Proteins and Antioxidant Enzymes between Human and Rodent Pancreatic Islets: Implications for the Pathogenesis of Insulin-Dependent Diabetes Mellitus Effects of hydrogen peroxide, nicotinamide and nitroprusside on human islet GSH contents GSH levels of dispersed human islet cells were determined as given in Fig. 6. Values are means ± SEM for two to three experiments, except with the 0.2 mM HP + 50 mM NA addition which represents only one observation. *p < 0.05 for a chance difference between control cells and cells incubated with 50 mM NA using Student’s paired t test. +p < 0.05 for a chance difference between 0.2 mM SP and 0.2 mM SP + 50 mM NA using Student’s paired t test. At all time points after Time 0, the 0.2 mM SP group was lower than controls (p < 0.05–0.01, Student’s paired t test).Back to article page
