Project description:The right legs of 8 Brown-Norway male rats were denervated by a high sciatic nerve section in the hip region of the hind limb.Two months after denervation (6 months of age), extensor digitorum longus (EDL) muscles were removed from the operated legs. The EDL muscles from 8 age-matched non-operated rats served as innervated controls. Total RNA was isolated, labeled cDNA was prepared and hybridized to the Rat Atlas 1.2 Array II membranes (Clontech Laboratories, Palo Alto, CA). Keywords: other
Project description:Identification of targets of the protein disulfide reductase thioredoxin using liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) and thiol specific differential labeling with isotope-coded affinity tags (ICAT). Reduction of specific target disulfides is quantified by measuring ratios of cysteine residues labeled with the heavy (13C) and light (12C) ICAT reagents in peptides derived from tryptic digests of Trx-treated and non-treated samples. Keywords: protein, LC-MS/MS, ICAT
Project description:We investigated morphometric structure and gene expression by microarray analysis in a small diameter artery, branch of the saphenous artery (a resistance artery), in representative models of renin-angiotensin system (RAS)-dependent and glucocorticoid hypertension, using the spontaneously hypertensive rat (SHR) and adrenocorticotropic hormone (ACTH)-induced hypertensive rat, respectively. Sixteen-week-old male Wistar-Kyoto (WKY) and age-matched spontaneously hypertensive rats (SHR) were used. Keywords: Comparison of global gene expression in resistance arteries of normotensive and genetically hypertensive rats and ACTH-treated rats.
Project description:LC-MSMS (Label free) was performed to find differential proteins in maternal rat serum exosome between 3 normal pregnant rats and 3 pregnant rats carrying fetuses with spina bifida aperta induced by all-trans retinoic acid (Sigma; 4% [wt/vol] in olive oil; 140 mg/kg body weight by gavage) at pregnant day E18 (vaginal smear found sperm after mating as E0).
Project description:Label-free proteomics from colon tumors induced in C57BL/6J mice following exposure to azoxymethane plus dextran sodium sulfate. Normal colon was taken from age matched mice not exposed to AOM/DSS.

Project description:Profiling of N-linked glycoproteomes in rat lymph before and after gastric bypass surgery. The cohort consisted of 68 lymph samples originating from rats before and after gastric bypass surgery (RYGB) or placebo surgery (SHAM). Samples were collected from rats before, 5 days, 10 days and 21 days after the operation. The samples for this study were processed using a Versette automated liquid handling system (ThermoFisher Scientific) in a 96-well plate format. The samples were measured in label free DDA mode and glycopeptides were quantified using Progenesis (Nonlinear Dynamics).
Project description:We used old (~96-102 weeks of age) and young (~28-34 weeks of age) rats from HCR and LCR generations 29 and 32, respectively. The study included eight groups; HCR-Old-Exhausted (H-O-E, n=6), HCR-Old-Rest (H-O-R, n=6), HCR-Young-Exhausted (H-Y-E, n=6), HCR- Young -Rest (H-Y-R, n=6), LCR-Old-Exhausted (L-O-E, n=6), LCR-Old-Rest (L-O-R, n=6), LCR-Young-Exhausted (L-Y-E, n=6), and LCR- Young -Rest (L-Y-R, n=6). For the exhausted rats, dissections were performed within 10 min after the maximal running distance was reached. We extracted skeletal muscle RNA from a total of 48 female animals (n=6 in each of the 8 group). Skeletal muscle tissue was obtained from the Extensor digitorum longus (EDL). All rats were dissected immediately after sacrificing, and all tissue samples were immediately weighed and snap frozen in liquid nitrogen, and stored at -80 ºC. Total RNA was extracted from frozen tissue with Trizol reagent (Invitrogen, Carlsbad, CA), treated with DNase-free (Invitrogen, Carlsbad, CA) and cleaned up with RNeasy columns (Qiagen, Hilden, Germany)
