Next-generation Sequencing Facilitates Quantitative Analysis of Wild Type and EED cKO mice Hippocampus Dentate Gyrus Transcriptomes

Project description:Purpose:Quantification differentially expressed genes and find target genes. The goals of this study are to compare Wild Type and EED cKO hippocampus dentate gyrus transcriptome profiling (RNA-seq) to quantitative reverse transcription polymerase chain reaction (qRT–PCR) differentially expressed genes and find target genes Methods: Hippocampus dentate gyrus mRNA profiles of 14-day-old wild-type (WT) and Embryonic Ectoderm Development conditional knockout (EED cKO) mice were generated by deep sequencing, in two biological replicates,using BGISEQ-500 platform.All RNA-Seq data were aligned to mouse genome version mm10 using HISAT.We use cluster software and Euclidean distance matrix for the hierarchical clustering analysis of the expressed gene and sample program at the same time, the clustering results can be viewed with javaTreeview. qRT–PCR validation was performed using SYBR Green assays. Results:Only transcripts that showed more than 2-fold differential expression compared to control were subjected to relevance network analysis. 1047 candidate genes that were differentially expressed with biological functional groups as compared between WT and EED cKO mice . Conclusions: Our study represents the first detailed analysis of Wild Type and EED cKO mice hippocampus dentate gyrus transcriptomes, with two biologic replicates, generated by RNA-seq technology.

Single-Cell Analysis of Aging Mouse Dentate Gyrus

Project description:The dentate gyrus of the hippocampus is a brain region involved in learning, memory formation, and spatial coding. We performed single-cell RNA-sequencing of the dentate gyrus of young and old mice to identify the age-induced changes.

RNA-sequencing to identify differentially expressed mRNAs after knockout of YTHDF2 in granule cells of mouse hippocampus dentate gyrus

Project description:To identify differentially expressed mRNAs after knockout of YTHDF2 in granule cells of mouse hippocampus dentate gyrus, we perfromed RNA-seq. Total RNA from DG deficient in YTHDF2 and the negative control DG were collected and subjected to construct sequencing libraries using NEBNext® Ultra™ RNA Library Prep Kit for Illumina® (NEB). After sequencencing, the filtered reads were mapped to the mouse reference genome (GRCm38) using HISAT2 v2.0.5 with default parameters. The resulting bam files were fed to featureCounts v1.5.0-p3 to count the number of RNA-seq reads, which was further normalized to calculate FPKM. Differential expression analysis of two groups (cKO vs NC) (three biological replicates per group) was performed using the DESeq2 package (version 1.20.0). Altogether 779 mRNA were differentially regulated, among which 536 mRNA were upregulated after YTHDF2 KD. This study provides a gene list which shows differentially expressed mRNAs after knockout of YTHDF2 in granule cells of mouse hippocampus dentate gyrus.

Analysis of transcriptome in dorsal hippocampus in response to over-expression of hepatic leukemia factor (Hlf) in dentate gyrus neurons

Whole transcriptome analysis of postmortem human hippocampus dentate gyrus granlule cells

Project description:We investigated the transcriptome of dentate gyrus (DG) granule cells in postmortem hippocampus from 79 subjects with mental illness (schizophrenia, bipolar disorder, major depression) or non-psychiatric controls. Material for RNA-seq analysis was harvested from tissue slides using laser capture microdissection (LCM) and aRNA amplification. Equimolar amounts of triplicate aRNA samples for each of the 79 subjects were then pooled for the preparation of sequencing libraries. Sequencing libraries were prepared using Applied Biosystem's Total RNA Sequencing Kit, following the directions for Whole Transcriptome Libraries, and analyzed with an Applied Biosystems SOLiD 4 high-throughput sequencer. We compared the performance of different normalization methods (length normalization vs. noise reductin scaling), and assembled evidence for dysruption of signaling by the micro RNA miR-182 in subjects with major depression and schizophrenia.

Transcriptome analysis of long term potentiation in rat dentate gyrus

Project description:In vivo high frequency stimulated of left dentate gyrus was performed on anaesthetised rats followed by RNA-seq to study long-term potentiation. Both left and right dentate gyrus was collected, sequenced and compared against each other for naive rats and for rats 30 min, 2 hours, and 5 hours post-HFS.
