(Submitter supplied) A new safety testing paradigm that relies on gene expression biomarker panels was developed that can easily and quickly identify dose-dependent drug-induced injuries across a number of different tissues in rats prior to drug candidate selection. The resource-sparing approach has yielded positive impact on early compound de-risking, enabling drug advancement in a cost-effective manner while reducing later probability of attrition. more...

(Submitter supplied) The robust transcriptional plasticity of liver mediated through xenobiotic receptors underlies its ability to respond rapidly and effectively to diverse chemical stressors. Thus, drug-induced gene expression changes in liver serve not only as biomarkers of liver injury, but also as mechanistic sentinels of adaptation in metabolism, detoxification and tissue protection from chemicals. Modern RNA sequencing methods offer an unmatched opportunity to quantitatively monitor these processes in parallel and to contextualize the spectrum of dose-dependent stress, adaptation, protection and injury responses induced in liver by drug treatments. more...

(Submitter supplied) The rat has been used extensively as a model for evaluating chemical toxicities and for understanding drug mechanisms. However, its transcriptome across multiple organs, or developmental stages, has not yet been reported. Here we show, as part of the SEQC consortium efforts, a comprehensive rat transcriptomic BodyMap created by performing RNASeq on 320 samples from 11 organs of both sexes of juvenile, adolescent, adult and aged Fischer 344 rats. more...

(Submitter supplied) Although studies have established that exogenous growth hormone (GH) treatment stimulates growth in fish, its effects on target tissue gene expression are not well characterized. We assessed the effects Posilac® (Monsanto Co., St. Louis, MO), a recombinant bovine somatotropin, on tissue transcript levels. Transcript abundance was measure in liver and muscle using the GRASP 16 K cDNA microarray. A selection of the genes identified as altered with the microarray, and also transcripts for insulin-like growth factors, growth hormone receptors (GHR) and myostatins were measured by realtime PCR in the liver, muscle, brain, kidney, intestine, stomach, gill and heart. more...

(Submitter supplied) Transcriptional profiling in skeletal muscle of 48 pigs (132 days of age) originated from two lines divergently selected for residual feed intake (RFI) : low-RFI pigs (RFIneg), high-RFI pigs (RFIpl). Both lines were offered isocaloric and isoproteic diets with contrasted energy source and nutrients: low fat, low fiber (LF) diet or a high fat, high fiber (HF)diet during 10 weeks. Effects of RFI selection, diet and interaction between diet and line were investigated.

(Submitter supplied) The in vitro test battery of the European research consortium ESNATS (‘novel stem cell-based test systems’) has been used to screen for potential human developmental toxicants. As part of this effort, the migration of neural crest (MINC) assay has been used to evaluate chemical effects on neural crest function. It identified some drug-like compounds in addition to known environmental toxicants. The hits included the HSP90 inhibitor geldanamycin, the chemotherapeutic arsenic trioxide, the flame-retardant PBDE-99, the pesticide triadimefon and the histone deacetylase inhibitors valproic acid and trichostatin A. more...

We selected thioacetamide, an organosulfur compound extensively used in animal studies as a hepatotoxin and carcinogen for its ability to cause acute liver damage.

(Submitter supplied) Glyphosate-based herbicides (GBH) are the major pesticides used worldwide. Converging evidence suggests that GBH residues pose a particular risk to the kidneys and liver. However, the existence of biological effects with negative health implications at low environmentally relevant doses remains unresolved. A previous investigation addressed this issue, by conducting a 2-year feeding study, which included 10 female Sprague Dawley rats administered via drinking water with 0.1 ppb of a major Roundup formulation (50 ng/L glyphosate equivalent dilution). more...
