Project description:These data show differences in up- and down-regulation for protein abundances in the hippocampus of double blast vs. sham rats. Tandem mass tags (TMT)-MS results showed 136 up-regulated and 94 down-regulated proteins between the two groups. These TMT-MS findings revealed changes never described before in blast studies. In the absence of behavioral changes, these proteomic data further support the existence of an asymptomatic blast-induced molecular altered status (ABIMAS) associated with specific protein changes in the rat hippocampus.
Project description:To address the hypothesis that silencing deleterious or protective injury-induced genes in the rat hippocampus will reduce or increase the numbers of injured hippocampal neurons, alter cellular pathways essential for neuronal function and improve or worsen functional outcome after traumatic brain injury (TBI), we evaluated the effects of silencing neuronal nitric oxide synthase (nNOS) and glutathione peroxidase-1 (GPx-1) expression in the injured rat hippocampus.
Project description:Whole-genome bisulfite sequencing on the rat hippocampus identifies DMRs near genes concerning neuronal development and plasticity which are affected by an iron-deficient diet in pregnancy.
Project description:We performed high-throughput profiling of gene expression in rat hippocampus in response to chronic unpredictable mild stress (CUMS) and albiflorin treatment. Total 415 differentially expressed genes (DEGs) were identified in rat hippocampus in response to albiflorin treatment compared with CUMS rats treated with saline (CUMS-Sal). We conducted the integrated metabolomics and transcriptomics analysis and found the correction of 16 biochemical pathways by albiflorin such as sphingolipids, phospholipids, tryptophan metabolism, fatty acid oxidation, and purine and pyrimidine metabolism. Our study provided deep insights into the understanding of the molecular mechanisms underlying the rapid antidepressant actions of albiflorin.
