(Submitter supplied) Summary: The liver is the major site of gluconeogenesis, fat processing and distribution, as well as drug and xenobiotic metabolism. Altered gene expression in the liver is centrally invovled in both the immuosuppressive and the energetic actions of corticosteroids. Hypothesis: That pharmacodynamics can be derived from expression profiling data. Specific Aim: The aim of this project is to identify distinct temporal patters of RNA expression in the liver of rats following a bolus dose of the corticosteroid methylprednisolone. more...

(Submitter supplied) Synthetic glucocorticoids are used therapeutically for a variety of conditions. Both the efficacy and toxicity of corticosteroids arise from their pharmacologically exaggerated effects on target and non-target tissues. For example, beneficial effects deriving from inhibition of the immune system are accompanied by toxic side effects that include hyperglycemia, dyslipidaemia, muscle wasting, fatty liver, and an increased risk of atherosclerosis. more...

(Submitter supplied) d-serine is naturally present throughout the human body. It is also used as add-on therapy for treatment-refractory schizophrenia. d-Serine interacts with the strychnine-insensitive glycine binding site of NMDA receptor, and this interaction could lead to potentially toxic activity (i.e., excitotoxicity) in brain tissue. The transcriptomic changes that occur in the brain after d-serine exposure have not been fully explored. more...

(Submitter supplied) RDX (Hexahydro-1,3,5-trinitro-1,3,5-triazine) is a synthetic, high-impact, relatively stable explosive that has been in use since WWII. Exposure to RDX can occur either occupationally or through ordnance that lays unexploded on training ranges. The toxicology of RDX is dominated by acute tonic-clonic seizures at high doses, which remit when exposure is removed and internal RDX levels decrease. Sub-chronic studies have revealed few other toxic effects. more...
