Transcription profiling of mouse AIN-centered DCN of delayed-type eyeblink conditioned mice (GEO Super Series)

ABSTRACT: This SuperSeries comprises the following subset Series:; GSE3651: The AIN-centered DCN of delayed-type eyeblink conditioned mice: 3-d paired training and sham negative control groups; GSE3652: The AIN-centered DCN of delayed-type eyeblink conditioned mice: 7-d paired and 7-d unpaired training groups; Anterior interpositus nucleus (AIN) is a proposed site of memory formation of eyeblink conditioning. A large part of the underlying molecular events, however, remains unknown. To elucidate molecular mechanisms, we examined transcriptional changes in the AIN of mice trained with delayed-type eyeblink conditioning; The data are not directly comparable between GSE3651 and GSE3652, given the different experimental time periods and amounts of cRNA used for hybridizations.

The anterior interpositus nucleus (AIN) is the proposed site of memory formation of eyeblink conditioning. A large part of the underlying molecular events, however, remain unknown. To elucidate the molecular mechanisms, we examined transcriptional changes in the AIN of mice trained with delay eyeblink conditioning using microarray, quantitative real-time RT-PCR, and in situ hybridization techniques. Microarray analyses suggested that transcriptionally up-regulated gene sets were largely differen ...[more]

Transcription profiling of mouse Anterior interpositus nucleus centred DCN from mice with of delayed-type eyeblink conditioned mice: 3-d paired training and sham negative control groups

Project description:Anterior interpositus nucleus (AIN) is a proposed site of memory formation of eyeblink conditioning. A large part of the underlying molecular events, however, remains unknown. To elucidate molecular mechanisms, we examined transcriptional changes in the AIN of mice trained with delayed-type eyeblink conditioning Experiment Overall Design: 3-d paired training group: Mice received a surgery for implanting four Teflon-coated stainless-steel wires in their left eyelid and a headstage on their head. After 3daysâ?? recovery, they were trained with paired paradigm of conditioned stimulus (CS) and unconditioned stimulus (US) for 3days: A 352-ms tone CS (1kHz, 83~85dB) was delivered first and a 100ms periorbital shock US (100kHz square pluses) were delivered with 252ms after the onset of CS, and they co-terminated. After the last trial was given, anterior interpositus was immediately sampled in 10 to 30 min from the sacrifice. Experiment Overall Design: Sham negative control group: Mice received a surgery for implanting four Teflon-coated stainless-steel wires in their left eyelid and a headstage on their head. After recovery, anterior interpositus nucleus-centered deep cerebellar nuclei were immediately sampled in 10 to 30 min from the sacrifice. Experiment Overall Design: ~10-15 anterior interpositus-centered deep cerebellar nuclei ipsilateral to the eye implanted with four wires were pooled into the same sham control or training group and subjected to microarray analysis.

Transcription profiling of decidua basalis from women with normal pregnancies or preeclampsia and/or fetal growth restriction

Project description:The aim of the study was to compare gene expression profiles in decidua basalis from cases with complicated pregnancies to those from healthy pregnant controls. Cases included pregnant women with preeclampsia (PE) and/or fetal growth restriction (FGR). Decidual tissue was obtained by vacuum suction of the placental bed after the placenta was delivered. Women with PE and/or FGR were included as cases. PE was defined as persistent hypertension (blood pressure (BP) ¡Ý 140/90 mm Hg), plus proteinuria (¡Ý0.3g/24 h or ¡Ý2+ according to a dipstick test), developing after 20 weeks of pregnancy. FGR implied birth weight under 2 standard deviations (SD) below the expected birth weight, as related to gestational age (GA) and sex. Due to tissue sampling procedures, only cases delivered by cesarean section (CS) were included. Healthy women with normal pregnancies, undergoing CS for various reasons considered irrelevant to the aim of this study (e. g. breech presentation and previous CS), served as controls. Tissue was immediately submerged in a RNA stabilisation solution (RNAlater, Ambion, Huntingdon, U.K.), incubated at 4¡ãC overnight and stored at -80¡ãC

Multi-omics analysis identifies ALDH7A1 as a key regulator of the visual-olfactory bimodal learning in honeybee

Project description:Specific genes or encoded proteins are involved in regulating various learning models of different species through certain signaling pathways，but whether there are also regulatory genes during bimodal learning and memory is largely unknown. Using a multi-omics approach to examine gene expression changes in bees brain performed with three different learning assays, a general up-regulation of genes and proteins were observed in bimodal learning compared to controls. Protein-protein network predictions of differential proteins together with FISH assays suggest ALDH7A1 may be involved in regulation of bimodal learning and memory. Injecting siRNA-ALDH7A1 to the bee brain results in significant inhibition the expressions of ALDH7A1 and regucalcin, and increase β-alanine content. Interestingly, we found that loss of ALDH7A1 only affect visual-olfactory bimodal learning and memory, but not single visual or olfactory conditioned learning after ALDH7A1-RNAi in bees. Therefore, our data suggests that ALDH7A1 may affect bimodal learning and memory though controlling β-alanine related plasticity mechanisms.

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).

RNA-Sequencing of USP15 conditional knock-out mice injected with kainate - dataset 2

Project description:Transcriptome studies of brain resections from mesial temporal lobe epilepsy (mTLE) patients revealed a dysregulation of transforming growth factor (TGF)-β, interferon (IFN)-α/β and nuclear factor erythroid 2-related factor 2 (NRF2) pathways among other neuroinflammatory mechanisms. Since ubiquitin-specific proteases (USP), in particular USP15, have been shown to regulate these pathways, we hypothesized that the blockade of USP15 may provide therapeutic relief in treatment-resistant epilepsies. The intrahippocampal kainate mouse model for mTLE, an established model for pharmacoresistant epilepsy was used for validation of USP15 as a therapeutic target. Transgenic mice which inducibly lack USP15 underwent intrahippocampal kainate injections to investigate the impact of USP15 downregulation at the transcriptomic level.

Bursaphelenchus xylophilus secretome under Pinus pinaster and P. pinea stimuli

Project description:The pinewood nematode, Bursaphelenchus xylophilus, the pine wilt disease's causal agent, is a migratory endoparasitic nematode skilled to feed on pine tissues and on fungi that colonize the trees. In order to study B. xylophilus secretomes under the stimulus of pine species with different susceptibility to disease, nematodes were exposed to aqueous pine extracts from Pinus pinaster (high susceptible host) and P. pinea (low susceptible host). Sequential windowed acquisition of all theoretical mass spectra (SWATH-MS) was used to determine relative changes in protein amounts between B. xylophilus secretions, and a total of 776 secreted proteins were quantified in both secretomes.

The Drosophila melanogaster Transcriptome by Paired-End RNA-Sequencing

Project description:RNA-seq was used to generate an extensive map of the Drosophila melanogaster transcriptome by broad sampling of 10 developmental stages. In total, 142.2 million uniquely mapped 64-100bp paired-end reads were generated on the Illumina GA II yielding 356x sequencing coverage. More than 95% of FlyBase genes and 90% of splicing junctions were observed. Modifications to 30% of FlyBase gene models were made by extension of untranslated regions, inclusion of novel exons, and identification of novel splicing events. A total of 319 novel transcripts were identified, representing a 2% increase over the current annotation. Alternate splicing was observed in 31% of D. melanogaster genes, a 38% increase over previous estimations, but significantly less than that observed in higher organisms. Much of this splicing is subtle such as tandem alternate splice sites. Poly(A)+ transcripts from 10 distinct stages during the live cycle of D. melanogaster were isolated to generated cDNA libraries which were sequenced on the Illumina GA II instrument.
