Gene expression induced by trace fear conditioning in murine hippocampus

ABSTRACT: Gene expression profiling following different learning paradigms may help in defining the moleular pathways of memory formation. In this study we analyzed the gene expression pattern of murine hippocampus at different time points (0.5 h, 2h, 6h) after trace fear conditioning. We compared trained mice with naive mice that remained in their homecages. Keywords: Time course We used 3 arrays for each experimental condition. Each array was hybridized witha a pool of RNA of 6 animals.

In this paper we report the results of gene expression profiling of C57Bl/6N mice hippocampus after trace fear conditioning (TFC), and the identification of genes regulated at early and late steps after conditioning. Several of the genes regulated at early steps following TFC appeared common to many training protocols. At later stages (2 and 6 h), most of the genes identified were different from those identified following other learning paradigms resulting in memory consolidation. At 6 h after t ...[more]

LincRNAs involved in DCS-induced fear extinction: Shedding light on the transcriptomic dark matter

Project description:There is a growing appreciation of the role of non-coding RNAs in the regulation of gene and protein expression. Long non-coding RNAs can modulate splicing by hybridizing with precursor messenger RNAs (pre-mRNAs) and influence RNA editing, mRNA stability, translation activation and microRNA-mRNA interactions by binding to mature mRNAs. LncRNAs are highly abundant in the brain and have been implicated in neurodevelopmental disorders. Long intergenic non-coding RNAs are the largest subclass of lncRNAs and play a crucial role in gene regulation. We used RNA sequencing and bioinformatic analyses to identify lincRNAs and their predicted mRNA targets associated with fear extinction that was induced by intra-hippocampally administered D-cycloserine in an animal model investigating the core phenotypes of PTSD. We identified 43 differentially expressed fear extinction related lincRNAs and 190 differentially expressed fear extinction related mRNAs. Eight of these lincRNAs were predicted to interact with and regulate 108 of these mRNAs and seven lincRNAs were predicted to interact with 22 of their pre-mRNA transcripts. On the basis of the functions of their target RNAs, we inferred that these lincRNAs bind to nucleotides, ribonucleotides and proteins and subsequently influence nervous system development, and morphology, immune system functioning, and are associated with nervous system and mental health disorders. Quantitative trait loci that overlapped with fear extinction related lincRNAs, included serum corticosterone level, neuroinflammation, anxiety, stress and despair related responses. This is the first study to identify lincRNAs and their RNA targets with a putative role in transcriptional regulation during fear extinction.

K63 polyubiquitin targets in the hippocampus of male and female rats following contextual fear conditioning

Project description:This experiment examined K63 polyubiquitin protein targets in the male and female hippocampus after contextual fear conditioning. Samples were the CA1 region of the dorsal hippocampus collected from male and female Sprague-Dawley rats that were 8-9 weeks old. Samples were collected 1 hour after contextual fear conditioning (Trained) or from non-stimulated controls (Naïve).

Gene-expression changes in neurons active during contextual fear conditioning compared to controls left in the homecage

Project description:This experiment uses a transgenic mouse that allows for activity-induced expression of an HA-tagged ribosome in an inducible and cre-dependent manner. This allowed us to assess long-lasting gene-expression changes in neurons active during contextual fear conditioning. Previous studies have used similar systems to look a transient changes in gene expression in these neurons, but we developed a system to look at long lasting changes. The workflow includes tissue dissection of the prefrontal cortex, tissue homogenization followed by an immunoprecipitation of the tagged ribosomes using antibodies against HA. RNA bound to the ribosomes is then purified, a cDNA library is prepared and RNAseq was performed. The experimental group was fear conditioned and the control group was left in their homecage for induction of HA- expression in active neurons.

Microarray dataset of gene transcription in mouse microglia and peripheral monocytes in contextual fear conditioning

Project description:Using Illumina MouseWG-6v2 microarrays, we investigated the gene transcription changes in microglia and peripheral monocytes after contextual fear conditioning of C57BL/6J mice. Mice were trained with or without a single minimized footshock stimulation (0-s or 2-s, 0.4 mA) and re-exposed to the training context without footshock for three different durations 24 h later: 0 min (FS0), 3 min (FS3), or 30 min (FS30). Whole brain microglia and peripheral monocytes were prepared 24 h after re-exposure using a neural tissue dissociation kit, including non-footshock controls for two re-exposure durations (Con3 and Con30). The data can be valuable for researchers interested in glial cells and neurotransmission studies and are related to the research article “Contextual fear conditioning regulates synapse-related gene transcription in mouse microglia”.

RNA-seq analysis of contextual fear conditioning

Project description:This dataset constitutes the first RNA-seq study of gene expression following contextual fear conditioning in the mouse hippocampus. 15 total samples were analyzed, including animals trained in a contexual conditioning paradigm (FC) and controls. Tissue was collected at 30 minutes (FC), as well as 30 minutes after testing for retrieval of the memory (RT). Testing was performed at 24 hours after training over a 5-minute interval. Animals that were handled but not trained were dissected at the same time of day to control for variations due to circadian rhythms (CC3). The protocol was repeated over the course of 5 days to obtain 9 animals (2 hippocampi) per group, so that 5 independent FC experiments were represented in each time point and all animals for each group were dissected at the exactly the same time of day.
