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

ABSTRACT: 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.

Genome-wide maps of chromatin changes uppon contextual fear conditioning in mice (RNA-seq)

Project description:The ability to form memories is a prerequisite for an organismâs behavioural adaptation to environmental changes. At the molecular level, the acquisition and maintenance of memory requires changes in chromatin modifications. In an effort to unravel the epigenetic network underlying both short- and long-term memory, we examined chromatin modification changes in two distinct mouse brain regions, two cell-types, and three time-points before and after contextual learning. Here we show that histone modifications predominantly change during memory acquisition and correlate surprisingly little with changes in gene expression. While long-lasting changes are almost exclusive to neurons, learning-related histone modification and DNA methylation changes occur also in non-neuronal cell types, suggesting a functional role for non-neuronal cells in epigenetic learning. Finally, our data provides evidence for a molecular framework of memory acquisition and maintenance, wherein DNA methylation could alter the expression and splicing of genes involved in functional plasticity and synaptic wiring. We examined chromatin modification changes in two distinct mouse brain regions (CA1 and ACC), two cell-types (neurons, non-neurons), and three time-points before and after contextual learning (naive, 1h, 4w).

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).

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.

Contextual fear conditioning induced transcriptional changes in hippocampal CA1 neurons

Project description:The goal of our study was to assess whether the experience can regulate specific lncRNAs within the hippocampus and their role in associative memory. To address this, we carried out unbiased analyses of gene expression in CA1-hippocampal neurons to identify lncRNA changes induced by contextual fear conditioning (CFC).
