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).

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 in rat hippocampal CA1 during the extinction of contextual fear memory

Project description:Adult rats (male Lister hooded) were pre-exposed for 3 d for 10 min /d (24 hr interval) to two different novel contexts. On day 4 rats received a single unsignaled scrambled footshock (0.5 mA for 2 s) 2 min into a 3min exposure to one of the two contexts. Rats were either returned to the CS conditioned context (CS+, EXT group) or to the other (CS-, NOR group) context for 10 min, 48h after contextual fear conditioning. Rats were housed in the home cages at all times outside the conditioning and re-exposure components. The novel context chosen to be the conditioned context was counterbalanced across the experimental groups. Rats were killed by CO2 inhalation 2 hours after CS- or CS+ exposure. CA1-enriched dorsal hippocampus was immediately dissected on ice before rapid freezing and storage at -80oC. The CS+ group represents rats that underwent extinction of contextual fear memory.

Gene expression in rat hippocampal CA1 during the consolidation of contextual fear memory

Project description:Adult rats (male Lister hooded) received a single unsignaled scrambled footshock (0.5 mA for 2 s) 2 min into a 3min exposure to a novel context. One half rats received bilateral microinfusions (1 microlitre/hemisphere) of 2 nmol/microlitre BDNF antisense ODN (BDNFASO, 5’-TCTTCCCCTTTTAATGGT-3’ in PBS, pH 7.4) or BDNF missense ODN (BDNFMSO, 5’ -ATACTTTCTGTTCTTGCC-3’ in PBS, pH 7.4) into the dorsal hippocampus (AP -3.50, relative to bregma), 90 min before contextual fear conditioning (CFC). Infusions were made in awake rats via previously surgically implanted indwelling stainless steel cannula. Rats were housed in the home cages at all times outside the conditioning procedure. Rats were killed by CO2 inhalation 2 hours after CFC. CA1 enriched dorsal hippocampus was immediately dissected on ice before rapid freezing and storage at -80oC. The BDNFASO-infused group represent consolidation-impaired rats.

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.

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”.

Time-lapse hippocampal transcriptomic profiling after fear conditioning in Tob WT and KO mice

Project description:Fear conditioning induces immediate changes in the mouse hippocampal transcriptome profile. Here, we performed RNA sequqencing in mice hippocampi at 15 minutes, 1 hour and 3 hours post-fear conditioning in addition to non-conditioned mice. Tob gene has been shown to affect cellular stress and behavior. In order to understand the role of Tob gene in the hippocampal stress and fear machinery, we compared hippocampi of Tob WT and KO mice. This dataset shows the temporal transcriptomic changes in mouse hippocampus induced by fear conditioning. Also, it shows the changes occurred after Tob deletion.
