Results4.1. 5-AzaC treatment of P7 mice inhibits DNA methylation and activates TL1A/TNFSF15 Protein site caspase-3 Previous research report that the administration of the DNA methylation inhibitor 5-AzaC to pregnant animals causes apoptotic cell death within the embryonic brain [54]. However, it is not identified no matter if the inhibition of DNA methylation by 5-AzaC for a brief period for the duration of synaptogenesis (a very sensitive stage for apoptotic cell death [558]) causes caspase-3 activation. The outcomes showed that 5-AzaC inhibits DNA methylation in a dose-dependent manner (Fig. 1A; hippocampus, F4, 35 = 112, p 0.01; neocortex, F4, 35 = 30, p 0.01; cerebellum, F4, 35 = 28, p 0.01) (two-way ANOVA). We also observed a considerable reduction in the quantity of 5-mC in the genomic DNA in the 5-AzaC-treated P7 mice HP (F1, 46 = 25, p 0.01), NC (F1, 46 = 20, p 0.01) and CB (F1, 46 = 15, p 0.01) (one-way ANOVA with Bonferroni’s post hoc tests) when compared with the saline groups (1B). The dot blots were normalized to the percentage on the saline (the graphs represent the 5-mC levels multiplied by an arbitrary aspect to set the saline to 100). Manders coefficient evaluation suggests that 5-AzaC-treatment substantially (p 0.01) lowered the 5-mC positive NeuN neurons in hippocampus (CA1 region), retrosplenial cortex (RSC) and cerebellum (CB) brain regions (Fig. 1C) when in comparison with saline therapy groups. 5-AzaC also induces the formation of CC3 inside the hippocampus (F4, 37 = 55, p 0.01) and neocortex (F4, 37 = 58, p 0.01) (Fig. 2A) (two-way ANOVA) in a dose-dependent manner but didn’t induce the formation of CC3 within the cerebellum (p 0.05) at any with the doses examined. 5-AzaC also induces the formation of CC3 in the hippocampus, (F1, 46 = 45, p 0.01) and neocortex, (F1, 46 = 38, p 0.01) (one-way ANOVA with Bonferroni’s post hoc tests) of neonatal mice at 8 and 24 h. The CC3 levels returned to standard levels by 48 h just after the 5-AzaC remedy (Fig. 2B). We then examined CC3 IHC right after 8 h of 5-AzaC exposure. We counted the CC3-positive cells (4 sections/brain) in the hippocampus and cortex [hippocampus (F1, 11 = 54, p0.01) and cortex (F1, 11 = 80, p0.01) regions] (one-way ANOVA). The results suggest that the 5-AzaC remedy enhanced caspase-3 activation, as indicated by the increased quantity of CC3-positive cells in the 5-AzaC-exposed brain sections (five mg/kg, s. c. at 8 h) (Fig. 2C). 4.2. 5-AzaC treatment of P7 mice inhibits ERK1/2 phosphorylation and Arc protein expression To additional evaluate the participation of intracellular signaling events in the effects of 5-AzaC around the creating brain, we determined the levels of both pERK1/2 (activated), ERK1/2 (total) and Arc proteins. The 5-AzaC treatment substantially decreased the pERK1/2 and Arc protein levels in the hippocampus (pERK1/2, F1, 37 = 34, p0.01; Arc, F1, 37 = 54, p0.01)Physiol Behav.
