(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) PURPOSE. Triamcinolone acetonide (TA) and dexamethasone (DEX) are corticosteroids commonly used for ocular inflammation but both can cause ocular hypertension. We investigated the differential gene expression profile of human trabecular meshwork (TM) cells in response to treatment by TA compared to that by DEX. METHODS. Total RNA was extracted from cultured human TM cells treated with TA or DEX and used for microarray gene expression analysis. more...

(Submitter supplied) Objectives: We monitored the mRNA expression profiles of peripheral blood cells during treatment with a tumor necrosis factor-a inhibitor, infliximab, in patients with rheumatoid arthritis (RA). Using a DNA microarray analysis, we demonstrated a unique set of genes, with distinct baseline and post-treatment changes in expression between responders and non-responders to infliximab treatment.Methods: Using a customized low-density cDNA microarray and a reliable data collection system, we monitored the mRNA expression profiles of whole blood cells from 18 RA patients before and after the infusion of infliximab for up to 22 weeks. more...

(Submitter supplied) Soman (O-Pinacolyl methylphosphonofluoridate) is a potent neurotoxicant. Acute exposure to soman causes profound inhibition of the critical enzyme acetylcholinesterase, resulting in excessive levels of the neurotransmitter acetylcholine. Excessive acetylcholine levels cause convulsions, seizures, and respiratory distress. The initial cholinergic crisis can be overcome by rapid anti-cholinergic therapeutic intervention, resulting in increased survival. more...

(Submitter supplied) Age-related macular degeneration has a strong epidemiological association with cardiovascular disease. One pathogenic hypothesis that applies to both diseases is the concept of an abnormal cellular response to injury resulting in a disease phenotype. It has been hypothesized that this phenotype is also present in dermal fibroblasts. This study tests this hypothesis by examination of the expression profiles of fibroblasts obtained from diseased patients and subjected to sublethal cell injury. more...

(Submitter supplied) We used high density oligonucleotide arrays to measure the relative expression levels of ~27,000 probe sets in the left ventricles of inbred rat strains; DA (high performing), Copenhagen (COP, low performing), as well as F1(COPxDA) rats bred from these two strains whose performance was intermediate relative to both parental strains. DA and COP rats differ for both intrinsic aerobic running capacity (assessed with a treadmill exercise test to exhaustion) and intrinsic cardiac performance (as assessed by the Langendorff-Neeley working heart model). more...
