TranscriptomicsMicro-RNAs in Adult Long-Evans (Turku/AB) Rat Liver are Refractory to 96 Hours Dioxin Treatment
Dioxin-like chemicals are well-known for their ability to upregulate expression of numerous genes via the AH receptor (AHR). However, recent transcriptomic analyses in several laboratories indicate that dioxin-like chemicals or AHR genotype itself also can downregulate levels of mRNAs encoded by nu...

TranscriptomicsTranscription profiling of rat liver display strain-specific, hereditary and AHR-Dependent Components
Background; The rat is a major model organism in toxicogenomics and pharmacogenomics, and the use of steady-state hepatic mRNA levels to predict and understand drug toxicity and mechanism is well-established. Surprisingly, the inter- and intra-strain variability of rat mRNA expression has not been e...

TranscriptomicsNanoString analysis of a rat liver mRNA panel following TCDD treatment
Profiling of mRNA abundances with high-throughput platforms such as microarrays and RNA-Seq has become an important tool in both basic and biomedical research. However these platforms remain prone to systematic errors, and have challenges in clinical and industrial application. As a result it is sta...

TranscriptomicsPatterns of dioxin-altered mRNA expression in livers of dioxin-sensitive versus dioxin-resistant rats
The dioxin congener 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) causes a wide range of toxic effects in rodent species, all of which are mediated by a ligand-dependent transcription-factor, the aryl hydrocarbon receptor (AHR). The Han/Wistar (Kuopio) (H/W) strain shows exceptional resistance to many ...

TranscriptomicsMicro-RNAs in Adult Rat Liver are Refractory to 19 Hours Dioxin Exposure
Dioxin-like chemicals are well-known for their ability to upregulate expression of numerous genes via the AH receptor (AHR). However, recent transcriptomic analyses in several laboratories indicate that dioxin-like chemicals or AHR genotype itself also can downregulate levels of mRNAs encoded by nu...

TranscriptomicsTranscriptional Profiling of rat hypothalamic response to TCDD
In many mammals, halogenated aromatic hydrocarbon (HAH) exposure causes wasting syndrome, defined as lethal weight loss as a result of severe and persistent hypophagia. The most potent HAH in causing wasting is 2,3,7,8-tetrachlorodibenzo-ρ-dioxin (TCDD), which exerts its toxic effects through the ar...

TranscriptomicsTranscription profiling of rat samples response to dioxins (TCDD) to study the conserved transcriptional response of rat and mouse, see related set E-GEOD-10769 for mouse data
Background; Mouse and rat models are mainstays in pharmacology, toxicology and drug development – but differences between strains and between species complicate data interpretation and application to human health. Dioxin-like polyhalogenated aromatic hydrocarbons represent a major class of environ...

TranscriptomicsTranscriptional profiling of the rat hypothalamus response to TCDD
Rodents exposed to the environmental contaminant, TCDD, suffer from a number of acute and chronic toxicities, including lethality and a wasting syndrome. Hypothesizing that the wasting syndrome may be caused by changes in neural control of energy flux and metabolism, we profiled the transcriptional ...
