Microarray expression of kidney cortex in adult male rats treated with methylglyoxal vs. controls
Ontology highlight
ABSTRACT: In our study, we investigated the effect of methylglyoxal on metabolic, transcriptomic, metabolomic and proteomic profiles in the context of the development of kidney impairment in an experimental model of metabolic syndrome. Dicarbonyl stress was induced in experimental group by intragastrical administration of methylglyoxal (3x/ week in dose 0.5 mg/kg b.wt.for 4 weeks) in a strain of hereditary hypertriglyceridaemic rats (HHTg). Transcriptome assessment in kidney cortex was performed in 8 male adult rats of experimental group and compared to that of 6 age- and sex- matched rats of control group.

Transcriptome assessment in white adipose tissue was performed in 7 male adult rats of experimental group and compared to that of 6 age- and sex- matched rats of control group.
Project description:Adult male rats of the PD/Cub (PD hereafter) strains were fed a laboratory chow diet (STD, ssniff RZ, ssniff Spezialdiäten GmbH, Soest, Germany). At the age of 12 months, rats within each strain were randomly divided into two groups. The control group was fed a high-sucrose diet (HSD, sucrose 70 cal%) while the experimental group was fed a HSD fortified with quercetin (10 g/kg food, Sigma-Aldrich).
Project description:Adult male rats of the SHR/OlaIpcv (SHR hereafter) and SHR.PD-Zbtb16 strains were fed a laboratory chow diet (STD, ssniff RZ, ssniff Spezialdiäten GmbH, Soest, Germany). At the age of 12 months, rats within each strain were randomly divided into two groups. The control group was fed a high-sucrose diet (HSD, sucrose 70 cal%) while the experimental group was fed a HSD fortified with quercetin (10 g/kg food, Sigma-Aldrich).
Project description:We aimed to compare the transcriptome of liver, pancreas, and lung tissue of adult male SD rats and the novel CRISPR/Cas-9-mediated knockout SD-Nme7-/- adult male rats using Affymetrix Rat Gene 2.1 ST Array Strip. Total RNA was isolated from the liver, pancreas, and lung tissues (RNeasy Mini Kit, Qiagen) of SD and SDNme7-/- rats. The quality and integrity of the total RNA was evaluated on the Agilent 2100 Bioanalyzer system (Agilent, Palo Alto, CA). Microarray experiments were performed using the Rat Gene 2.1 ST Array Strip. The whole hybridization procedure was performed using the Affymetrix GeneAtlas® system according to the manufacturer's instructions. The quality control of the chips was performed using Affymetrix Expression Console. After applying quality filters and data normalization by the Robust Multichip Average (RMA) algorithm implemented in Affymetrix Expression Console, the set of obtained differentially expressed probesets was filtered by the false discovery rate (FDR) method implemented in PARTEK Genomics Suite 7 (Partek, St. Louis, Missouri). Transcriptomic data were then processed by a standardized sequence of analyses (hierarchical clustering and principal component analysis, gene ontology, gene set enrichment, Upstream Regulator Analysis, Mechanistic Networks, Causal Network Analysis, and Downstream Effects Analysis) using Ingenuity Pathway Analysis.
Project description:We aimed to compare the transcriptome of liver and white adipose tissue of adult male SD rats and the novel CRISPR/Cas-9-mediated heterozygous knockout SD-Nme7+/- adult male rats using Affymetrix Rat Gene 2.1 ST Array Strip. Total RNA was isolated from the liver and visceral adipose tissue (RNeasy Mini Kit, Qiagen) of SD and SDNme7+/- rats.

Project description:In this study, we assessed the effect of acute oral administration of ellagic acid on metabolic parameters, oxidative stress and transcriptomic profiles in an inbred rodent model, carrying a variant of one of the metabolic syndrome-related genes, Zbtb16 (Zinc Finger And BTB Domain Containing 16). Over a period of three weeks, adult male rats of the SHR-Lx/k.o. strain were fed a high-fat diet accompanied with daily intragastric gavage of ellagic acid (50 mg/kg body weight; HFD-EA rats) or solvent only (HFD rats). At the end of the protocol, morphometric and metabolic parameters, including glucose tolerance test, serum lipid concentration and oxidative stress markers along with transcriptomic profile of liver, brown, and epididymal adipose tissues were assessed.
Project description:We established a new minimal congenic rat strain containing only a single gene, Zbtb16, from a metabolic syndrome model, the polydactylous rat (PD/Cub) strain, within the spontaneously hypertensive rat (SHR) strain genomic background. 16-week-old SHR and SHR-Zbtb16 rat dams were fed either standard diet during pregnancy and 4 weeks of lactation (control groups) or a high-sucrose diet (HSD, 70% calories as sucrose) during the same period. We have compared the transcriptome profile (GeneChip Rat Gene 2.1 ST Array Strip) in liver, brown and white adipose tissue in adult male offspring of SHR and SHR-Zbtb16 rat dams.
Project description:The study aimed to analyse the effect of ovariectomy and estradiol substitution in a prediabetic model with insulin resistance – females of the hereditary hypertriglyceridemic rat strain (HHTg).
Project description:We aimed to clarify the cell-free DNA (cfDNA) physiological role. We exposed THP1 cells to plasma from healthy individuals with and without cfDNA and compared their transcriptomes and proteomes.
Project description:We aimed to compare transcriptome in heart and livers of spontaneously hypertensive rat SHR/OlaIpcv (Rat Genome Database ID: 631848) versus coisogenic rat strain SHR-Gja8m1Cub (Rat Genome Database ID: 2293729) using Affymetrix GeneChip® Rat Exon 1.0 ST Arrays in triplicate. Affymetrix GeneChip® Rat Exon 1.0 ST Array was used to determine the transcriptomic characteristics of the SHR and the coisogenic strain SHR-Dca. We extracted total RNA from the kidneys and hearts of 4-month old males of both strains using phenol-chloroform and purified with the RNeasy Mini kit (Qiagen, Valencia, CA, USA) in accordance with the manufacturerâs protocol. The quality of the total RNA was verified by the Agilent 2100 Bioanalyzer system. Double-stranded complementary DNA (cDNA) was synthesized from total RNA. The labeled and fragmented cDNA was pooled for each strain (SHR, SHR-Dca) and tissue (heart, kidney) and hybridized to Affymetrix GeneChip® Rat Exon 1.0 ST Arrays in triplicate (total 12 arrays). The whole hybridization procedure including DNA adjustment was performed according to the protocol recommended by Affymetrix.
