This implies that DNA methylation of promoter exon 1_7 may not underly the mechanism of GR up-regulation in GLP-1 -programmed rats.5 Hippocampal expression of GLP-1R and NGFI-A mRNAHippocampal GLP-1R (p =.009) and NGFI-A (p =.001) gene mRNA expression were significantly up-regulated in GP group as compared to VP group.Taken together, neonatal intramuscular injection of plasmid DNA encoding GLP-1 affects behavior and hippocampal GR expression in adolescent rats.
