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

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.

Cell types in the mouse amygdala and their transcriptional response to fear conditioning

Project description:We performed single-cell RNA-seq of full, microdissected and dissociated mouse amygdala, 2h, 8h or 24h after tone-cued fear conditioning (CFC), and 2h after recall (exposure to CS only, 24h post-CFC), and naive homecage controls.

Npas4 CUT&Tag in amygdala tissue after discriminative fear conditioning

Project description:Npas4 CUT&Tag dataset, Adult male WT C57BL/6J mice underwent discriminative fear conditioning and immediately injected saline. 90 minutes after fear conditioning, The amygdala tissue was extracted for further experiment. Npas4 CUT&Tag was performed to elucidate possible downstream targets which contributes regulation of fear expression during fear retreival.

Transcription profiling of rat amygdala following anesthesia with isoflurane, pain or following fear conditioning in the presence and absence of isofluran

Project description:Fear conditioning in rats leads to long term memory (LTM) formation. A central neural substrate for LTM is the basolateral amygdala. We sought the expression changes specific to LTM at 6h following anesthesia with isoflurane (a general anesthetic and an effective amnestic agent), following pain (a component of conditioning), and following conditioning in presence and absence of isoflurane.

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.

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.

Transcription profiling of brain tissue from mice after safety or fear conditioning

Project description:safety versus fear conditioning. Mice were trained with 4 unpaired (Safety) or paired (Fear) CS-US presentations over 3 days. Mice were killed by decapitation 4hrs after the last training session.

Dorsal hippocampal transcriptome analysis after Auditory Fear Conditioning and pharmacological GR modulation

Project description:Aim: We investigated the role of GR in Auditory Fear Conditioning memory consolidation by application of a pharmacological filter using selective glucocorticoid receptor modulators. Methods: Adult male mice were exposed to Auditory Fear Conditioning training and subsequently injected with 3.0 mg/kg corticosterone, 20 mg/kg CORT108297, 80 mg/kg CORT118335, 40 mg/kg RU486 or vehicle. Dorsal hippocampi were dissected 3 hours after injection and snap-frozen. Total RNA was isolated and send for 100bp paired-end sequencing by BGI.
