Fig. 3From: In diabetic male Wistar rats, quercetin-conjugated superparamagnetic iron oxide nanoparticles have an effect on the SIRT1/p66Shc-mediated pathway related to cognitive impairmentEffect of QC and QCSPIONs administration on (A) SIRT1, (B) p66Shc, (C) CASP3, and (D) PARP1 mRNA expression levels in the hippocampus of diabetic rats. NDC stands for non-diabetic control, DC for diabetic control, DC + SPION for diabetic treatment using a superparamagnetic iron oxide nanoparticle, DC + QC for diabetic treatment using quercetin, and DC + QCSPION for diabetic treatment using a quercetin-conjugated iron oxide nanoparticle. ** P < 0.01 and *** P < 0.001 and P < 0.0001 versus DC group (one-way ANOVA, Tukey’s multiple comparison tests). Mean values are expressed together with the standard error of the mean (SEM) (n = 5 per group)Back to article page
