Project description:Acetaminophen (APAP) Rat Blood Training Gene Expression Data Set
| PRJNA104357 | ENA
Project description:Acetaminophen (N-acetyl-p-aminophenol; APAP) is a mild analgesic and antipyretic used commonly worldwide. Although APAP is considered a safe and effective over-the-counter medication, it is also the leading cause of drug-induced acute liver failure. Its hepatotoxicity has been linked to the covalent binding of its reactive metabolite, N-acetyl p-benzoquinone imine (NAPQI), to proteins. The aim of this in vivo study was to identify APAP-protein targets in both rat and mouse liver, and to compare the results from both species, using bottom-up proteomics and targeted multiple reaction monitoring (MRM) experiments. Livers from rats and mice, treated with APAP, were homogenized and digested by trypsin. Digests were then fractionated by mixed-mode solid-phase extraction prior to liquid chromatography-tandem mass spectrometry (LC-MS/MS) using scheduled multiple reaction monitoring (MRM) acquisition. The targeted assays were optimized based on high-resolution MS/MS data from information-dependent acquisition (IDA) using control liver homogenates treated with a custom alkylating reagent forming a positional isomer of the APAP modification on all cysteine residues, in order to build an in-house modified peptide database for targeted analysis. A list of putative in vivo targets of APAP were screened from previous in vitro studies, data-dependent high-resolution MS/MS analyses of liver digests, as well as selected proteins from the target protein database (TPDB), an online resource which references previous reports of proteins found to be modified by acetaminophen. Multiple protein targets of APAP in each species were found, while confirming modification sites.

Project description:A series of two color gene expression profiles obtained using Agilent 44K expression microarrays was used to examine sex-dependent and growth hormone-dependent differences in gene expression in rat liver. This series is comprised of pools of RNA prepared from untreated male and female rat liver, hypophysectomized (‘Hypox’) male and female rat liver, and from livers of Hypox male rats treated with either a single injection of growth hormone and then killed 30, 60, or 90 min later, or from livers of Hypox male rats treated with two growth hormone injections spaced 3 or 4 hr apart and killed 30 min after the second injection. The pools were paired to generate the following 6 direct microarray comparisons: 1) untreated male liver vs. untreated female liver; 2) Hypox male liver vs. untreated male liver; 3) Hypox female liver vs. untreated female liver; 4) Hypox male liver vs. Hypox female liver; 5) Hypox male liver + 1 growth hormone injection vs. Hypox male liver; and 6) Hypox male liver + 2 growth hormone injections vs. Hypox male liver. A comparison of untreated male liver and untreated female liver liver gene expression profiles showed that of the genes that showed significant expression differences in at least one of the 6 data sets, 25% were sex-specific. Moreover, sex specificity was lost for 88% of the male-specific genes and 94% of the female-specific genes following hypophysectomy. 25-31% of the sex-specific genes whose expression is altered by hypophysectomy responded to short-term growth hormone treatment in hypox male liver. 18-19% of the sex-specific genes whose expression decreased following hypophysectomy were up-regulated after either one or two growth hormone injections. Finally, growth hormone suppressed 24-36% of the sex-specific genes whose expression was up-regulated following hypophysectomy, indicating that growth hormone acts via both positive and negative regulatory mechanisms to establish and maintain the sex specificity of liver gene expression.

Project description:In this study, we employed a strategy to screen miRNA expression profiles in liver tissue by miRCURY LNA(tm) microRNA array analysis followed by TaqMan probe-based quantitative reverse transcription-PCR (qRT-PCR) to validate the miRNA expression profiles in serum and liver of two parallel rat drug-induced liver injury (DILI) models induced by a compound (acetaminophen, APAP) or an herb (Dioscorea bulbifera, DB).
