Transcriptomic Characterization of Inhalation Phosphine Toxicity in Adult Male Sprague-Dawley Rats (21,252 ppm x min)

ABSTRACT: Phosphine (PH3) is a highly toxic, corrosive, flammable, heavier-than-air gas that is a commonly used fumigant. Although the mechanism of toxicity is unclear, PH3 is thought to be a metabolic poison. PH3 exposure induces multi-organ toxicity and no effective antidotes or therapeutics have been identified. To better characterize the mechanism(s) driving PH3-induced toxicity we have performed transcriptomic analysis on conscious adult male Sprague-Dawley rats following whole-body inhalation exposure to phosphine gas at three concentrations. PH3 exposure induced concentration- and time-dependent changes in gene expression across multiple tissues.

Chloroacetaldehyde treatment with 25 ppm for 2 h

Project description:The number and type of synthetic chemicals that are being produced worldwide continues to increase significantly. While these industrial chemicals provide numerous benefits, there is no doubt that some have potential to damage the environment and health. Toxicity must be evaluated and use must be carefully controlled and monitored in order to minimize potential damage. DNA microarray technology has become an important new technique in toxicology. We are using the yeast Saccharomyces cerevisiae as a model organism for toxicological study because it is a simple, fast-growing eukaryote that has been thoroughly characterized. In order to evaluate toxicity by newly synthesized or mixture chemicals, toxicity-induced gene expression alteration profiles by known chemicals should be collected. In our study, cells need to be exposed with same experimental cellular condition, semi lethal (IC50), respectively. In the case of chloroacetaldehyde (CAS; 107-20-0), the exposure dose was decided as 25 ppm by growth curve with continuously diluted exposure. Chloroacetaldehyde is one of the toxic gases and vapors. This substrate is suspected to be respiratory toxicant and skin or sense organ toxicant. Keywords: stress response

Illumina methylEPIC arrays on Peruvian individuals with high (>10 ppm) or low (<1 ppm) total hair mercury, a proxy for methylmercury exposure

Project description:Methylmercury (MeHg) is an environmental pollutant of global public health concern. MeHg is associated with immune dysfunction but the underlying mechanisms are unclear. The most common route of MeHg exposure is through consumption of fatty fish that contain beneficial n-3 polyunsaturated fatty acids (PUFA) that may protect against MeHg toxicity. To better inform individual costs and benefits of fish consumption, we aimed to identify candidate epigenetic biomarkers of biological responses that reflect MeHg toxicity and PUFA protection.

300 ppm Citrinin treatment for 2 h (GPL1945)

Project description:The availability of yeast DNA microarrays provides the possibility of monitoring gene expression levels as a function to toxin exposure, and consequently as a means of determining mechanisms of toxicity. This system possesses the benefit of the essential volume of yeast cultures, the high reproducibility of expression profiles, and the massive functional information. Because small amount of biological sample cultures are required for this analysis, toxicity test for rare chemical such as mycotoxins which is a natural compound and difficult to be artificially synthesized. Citrinin [518-75-2], 4,6-dihydro-8-hydroxy-3,4,5-trimethyl-6-oxo-3H-2-benzopyran-7-crboxylic acid, is the one of the popular mycotoxicin produced by Penicillium and Aspergillus family possibly spread all over the world. This natural chemicals is one of the well characterized mycotoxin but the information especially mechanism of toxic action is limited. We used two types of microarrays, one have ORF (Open reading Frame) fragment on the surface of the glass as probes and the other have probes as oligonucleotide probes on the microarray with 3 dimensions. We compared data properties and studied the toxicity of citrinin to yeast cells. Keywords: stress response Series containes 3 hybridization results from independent biological samples, and each experiment have high and low power scanned data respectively.
