Comparative dose-response analysis of liver and kidney transcriptomic effects of trichloroethylene and tetrachloroethylene in B6C3F1 mouse

Project description:Purpose: Trichloroethylene (TCE) and tetrachloroethylene (PCE) are ubiquitous environmental contaminants and occupational health hazards. The goals of this study were to establish the common and differing transcriptional effects of TCE and PCE. This study examined liver and kidney effects of TCE and PCE in a dose-response study design. Methods: Equi-molar doses of TCE (24, 80, 240, 800 mg/kg) or PE (30, 100, 300, 1,000 mg/kg) were administered by gavage in aqueous vehicle to male B6C3F1/J mice. Tissues were collected 24 hrs after exposure. Trichloroacetic acid (TCA), a major oxidative metabolite of both compounds, was measured and RNA sequencing was performed on liver and kidney samples, with ~30 samples for each organ (29 after QC). Results: Most dose-responsive pathways were common among chemicals/tissues, with the strongest effect on peroxisomal beta-oxidation. Effects on liver and kidney mitochondria-related pathways were notably unique to PCE. Tissue-specific acute transcriptional effects of TCE and PCE occurred at human equivalent doses comparable to those for apical effects. Conclusions: Our study is the first RNA-Seq transcriptional study of TCE vs. PCE in both liver and kidney, enabling a detailed comparison of the chemicals and effects on different organs. Our results show strong commonalities of effects, although PCE shows stronger transcriptional responses than TCE for the same equimolar doses.

5-Day Gavage Study of Crude 4-Methylcyclohexanemethanol in Male Harlan Sprague Dawley Rats

Project description:The goal of this study was to characterize the potential toxicity and genomic benchmark dose of crude 4-methylcyclohexylmethanol in liver and kidney of male Harlan Sprague Dawley rats using a 5 day dose-response toxicogenomics study design. The 5 day study is used to quickly identify the dose levels where changes in molecular pathways occur. These dose level where pathway level effects begin to occur have been shown to provide a close approximation of a no effect dose level from more resource intensive guideline toxicological assessments. A total of 44 samples were evaluated in this study. 27 were from liver and 17 were from kidney. Signficant batch effects were detected with a subset of samples and these were removed from the study prior to data analysis and are therefore not included in this GEO series. 3 (kidney) or 4 (liver) biological replicate were obtained for the 0 mg/kg/day control group for both liver and kidney. All other non-zero dose groups contain 2-4 biological replicates. The groups that contain only 2 or 3 replicates do so due to a number of samples not passing QC as byproduct of batch effects. The control groups for liver and kidney are the 0 mg/kg dose groups for those organs.

Cell death and regenerative proliferation pathways in hepatocellular carcinoma: The effect of furan on B6C3F1 mouse global gene expression in liver

Project description:Furan is a mouse and rat hepatocarcinogen. We sought to determine the dose-dependent changes in gene expression upon exposure of B6C3F1 mice to furan in order to better understand furan’s mode of action. Adult female B6C3F1 mice were exposed to 1, 2, 4 or 8 mg/kg bw furan or vehicle control (corn oil) for three weeks and sacrificed four hours after the final exposure. In this study we examined the transcriptional response in liver tissue of female B6C3F1 mice exposed to furan for 3 weeks at four different doses: 1, 2, 4 or 8 mg/kg bw furan (or vehicle control) and sacrificed four hours after the final exposure. Each dose group had 4-5 biological replicates. There were a total of 25 samples included in the final analysis. We used a two-colour reference design and SurePrint G3 Mouse GE 8x60K microarrays (Agilent).
