Project description:Propofol has been found to be toxic to developing neurons. The goal of the current study was to nominate novel genes predicted to underly the neurotoxicity, and use these candidates for future functional pathway assessment
Project description:We report the differentiation of dorsal and ventral hippocampus in developing rats by performing and analyzing transcriptome profiling.
Project description:SAGE profile of rat hippocampus mRNA from Wistar rats This GEO Series was created by the GEO staff as part of a cleanup effort to ensure that all GEO Samples are included within a Series entry.
Project description:We used LC-MS/MS based proteomics to identify changes in protein expression in the the female and male mouse hippocampus at 1, 2, and 4 months of age. This proteomics dataset was correlated with an accompanying mRNA dataset to identify genes that show mRNA changes in a different direction that their respective proteins. A modest correlation was found between mRNA and protein abundance in the mouse hippocampus (spearman rank coefficient = 0.53).
Project description:A variety of neurological disorders, including Alzheimer’s disease, Parkinson’s disease, major depressive disorder, dyslexia and autism, are differentially prevalent between females and males. To better understand the possible molecular basis for the sex-biased nature of neurological disorders, we measured both mRNA and protein in the hippocampus of female and male mice at 1, 2, and 4 months of age with RNA-sequencing and mass-spectrometry respectively. Differential expression analyses identify 2699 genes that are differentially expressed between animals of different ages. 198 transcripts are differentially expressed between females and males at one or more ages. The number of transcripts that are differentially expressed between females and males is greater in adult animals than in younger animals. Additionally, we identify 69 transcripts that show complex and sex-specific patterns of temporal regulation across all ages, 8 of which are heat-shock proteins. We also find a modest correlation between levels of mRNA and protein in the mouse hippocampus (Rho = 0.53). This study adds to the substantial body of evidence for transcriptomic regulation in the hippocampus during postnatal development. Additionally, this analysis reveals sex differences in the transcriptome of the developing mouse hippocampus, and further clarifies the need to include both female and male mice in longitudinal studies involving molecular changes in the hippocampus.
Project description:In this study we hypothesize that early life stress perturbs the normal function of microglial in the developing hippocampus and that this effect is responsible for the ability of early life tress to disrupt normal synaptic maturation, myelination, and axonal growth in the developing hippocampus. To test this hypothesis we used the mouse immune panel from NanoString in order to identify immune-related genes whose expression is modified by BDS, a mouse model of early life stress, in microglia isolated from the hippocampus of 28-day old male pups. This project is part of a manuscript that is currently under preparation (Delpech J.C. et al. Early life stress perturbs the maturation of microglia in the developing hippocampus, Brain, Behavior and Immunity, 2016)

To test this hypothesis we used the mouse immune panel from NanoString in order to identify immune-related genes whose expression is modified by BDS, a mouse model of early life stress, in microglia isolated from the hippocampus of 14-day old male pups.

Project description:Human hippocampus enabled further processing of higher brain functions. However, very little is known about human hippocampus development, which is largely accomplished during fetal stage. Our current study elucidates the transcriptomic profiling of the developing human fetal hippocampus using single-cell RNA-seq (scRNA-seq), allowing us to reconstruct the order of neurogenesis and their lineage relationships.
