ABSTRACT: We performed an RNA Sequencing experiment on dorsal hippocampal tissue from four groups of animals: Baf53b+/- homecage (Baf53b+/- HC); Baf53b+/- behavior (Baf53b+/- Beh); wildtype homecage (WT HC); and wildtype behavior (WT Beh). Homecage animals were sacrificed directly from the animal's cage. Behavior animals were sacrificed thirty minutes following Object Location Memory training. The objective of this study was to examine activity regulated gene expression following a learning event (HC vs Beh) in wildtype and Baf53b+/- mutant mice.

Examination of gene expression following a learning event in wildtype and Baf53b+/- mutant mice in dorsal hippocampus.
Project description:We performed an RNA Sequencing experiment on dorsal hippocampal tissue from six groups of animals: Aging (18-20-month-old) HDAC3flox/flox homecage (H3F-HC); Aging (18-20-month-old) HDAC3flox/flox 60min post training (H3F-BV); Aging (18-20-month-old) wildtype homecage (OWT-HC); Aging (18-20-month-old) wildtype 60min post training (OWT-BV); Young (2-4-month-old) wildtype homecage (YWT-HC); Young (2-4-month-old) wildtype 60min post training (YWT-BV). Homecage animals were sacrificed directly from the animal's cage. Behavior animals were sacrificed sixty minutes following a 10min Object Location Memory training session.
Project description:1-day-old C57BL/6 mice were left untreated (co) or orally infected with 10E2 CFU wildtype (wt) or delta invC SPI1 mutant Salmonella Typhimurium (ATCC14028). Four biological replicates obtained from individual animals were exmained; each group contained animals from at least 2 different litters. On day 4 p.i., animals were sacrificed and intestinal epithelial cells were isolated from total small intestine (protocol according to: Lotz et al., J. Exp. Med. 2006). Total RNA was isolated by TriZol and its purity was examined using a Bioanalyzer. We used microarrays to detail the global gene expression in primary total isolated intestinal epithelial cells.
Project description:These studies address temporal changes in gene expression during spontaneous sleep and extended wakefulness in the mouse cerebral cortex, a neuronal target for processes that control sleep; and the hypothalamus, an important site of sleep regulatory processes. We determined these changes by comparing expression in sleeping animals sacrificed at different times during the lights on period, to that in animals sleep deprived and sacrificed at the same diurnal time. Keywords: gene expression, temporal changes, brain, behavior, sleep,
Project description:CA1-specific brain tissue from the hippocampal formation was isolated at baseline (homecage condition) in wildtype and NEIL1, NEIL2 or NEIL1&2-deficient mice. NEILs are DNA glycosylases potentially involved in transcription regulation. RNA was extracted and sequenced.
Project description:We performed RNA sequencing and smallRNA sequencing experiments on visual cortex tissues from three groups of animals: wildtype mice postnatal day 10 (P10-WT), wildtype mice postnatal day 28 (P28-WT), and miR-132/212 null mice postnatal day 28 (P28-KO).
Project description:Mice were acclimatized for 2 weeks and randomly assigned to treatment and control groups (five per group). Animals were given a single dose of 250, 50, 5 and 0.5 mg/kg isoproterenol by oral gavage alongside 0.9% saline (vehicle control group)and sacrificed after eight hours. Total mouse liver RNA was isolated and used for the microarry analysis on custom oligonucleotide DNA microarray, the HC ToxArray V1.2.<br><br>
Project description:Wildtype mice at either 3 or 12 months old were subjected to intrahippocampal injection with sarkosyl insoluble brain extracts from either human control or Alzheimer's disease brain. Mice were incubated for 1, 3 or 5 months and then sacrificed. The hippocampus from one hemisphere was used to extract total RNA that was then subjected to polyA-selection and whole transcriptome sequencing. 3 and 12 month old animals were processed in seperate batches and comparisons between control and Alzheimer's disease injected animals from each timepoint were conducted
Project description:We have performed an unbiased, open-search analysis of the oxidative PTMs and quantitative multiplexed proteomics that take place in the pig ischemic heart tissue during the first 24h after I/R. We used 40 castrated male Large-White pigs weighing 30 to 40 kg. Closed-chest 40 min I/R was performed in 36 animals and they were sacrificed at 20 min, 40 min, 80 minutes, 2 hours, 6 hours, 12 hours and 24 hours after reperfusion after reperfusion (n = 4 per group). 4 animals were sacrificed with no intervention other than baseline cardiac magnetic resonance ( CMR), and served as controls. A new group of 4 animals were sacrificed at 120 minutes after artery occlusion without reperfusion, and other group of 4 animals were subjected to ischemic preconditioning prior to I/R and sacrificed at 24h. Myocardial tissue samples from ischemic area were collected for proteomics analysis.
Project description:To identify genes differentially expressed in the fatbody of Drosphila melanogaster bigmax mutants, a loss-of-function allele was generated by P-element mobilization. Mutant and wildtype first instar larvae were raised on two different sources of food, control and high-sugar media. When the animals reached the wandering third instar stage, animals were sacrificed and their fat bodies dissected. Total RNA was extracted, labeled fluorescently and hybridized competitively to Agilent's 4x44K Drosophila Gene Expression Microarrays. On each array, three different samples were analyzed: 1. wildtype animals raised on control food, 2. wildtype animals raised on high-sugar food and 3. bigmax mutant animals raised on high-sugar food.
