(Submitter supplied) We used expression quantitative trait locus mapping in the laboratory rat (Rattus norvegicus) to gain a broad perspective of gene regulation in the mammalian eye and to identify genetic variation relevant to human eye disease. Of >31,000 gene probes represented on an Affymetrix expression microarray, 18,976 exhibited sufficient signal for reliable analysis and at least 2-fold variation in expression among 120 F2 rats generated from an SR/JrHsd x SHRSP intercross. more...

(Submitter supplied) The Brown Norway (BN) strain of rat is an inbred normotensive strain. BN rats of both sexes present some interesting pathophysiological phenotypes involving arteries and the kidneys. These include internal elastic lamina (IEL) ruptures in the abdominal aorta and iliac arteries, a deficit in aortic elastin content, a persistent ductus arteriosus, hydronephrosis and hematuria. Spontaneous rupture of the internal elastic lamina occurs in various arteries during growth and aging, in different rat strains, both normotensive and hypertensive. 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...

Analysis of forebrains of animals treated with up to 500 mg/kg D-serine for 96 hours. D-serine is involved in many physiological processes through its interaction with the glycine binding site of the NMDA receptor. Results provide insight into the impact of D-serine exposure on neuronal functions.

(Submitter supplied) The use of statistical tools established for the genetic analysis of quantitative traits can be applied to gene expression data. Quantitative trait loci (QTL) analysis can associate expression of genes or groups of genes with particular genomic regions and thereby identify regions that play a role in the regulation of gene expression. A segregating population of 41 doubled haploid (DH) lines from the hard red spring wheat cross RL4452 x AC Domain was used. more...

(Submitter supplied) Gene expression information is useful in prioritizing candidate genes in linkage intervals. The data can also identify pathways involved in the pathophysiology of disease. We used microarrays to identify which genes are expressed in either intracranial arteries (control) or in intracranial aneurysms (case), and can therefore contribute to the disease phenotypes. We used microarrays to identify the pathway membership of expressed genes and the overrepresentation of pathways with expressed genes in the known linkage intervals for intracranial aneurysms. more...

(Submitter supplied) Background Haplotype association mapping is a recently developed method that can be used to identify expression Quantitative Trait Loci (eQTLs). The underlying genomic structure of the haplotype can be defined by single nucleotide polymorphisms (SNPs), variable number tandem repeats (VNTRs) and copy number variations (CNVs). Microarray genotyping platforms are able to interrogate all three genomic polymorphisms simultaneously. more...

(Submitter supplied) Studies using mice with beta4 nicotinic acetylcholine receptor (nAChR) subunit deficiency (beta4-/- mice) helped reveal the roles of this subunit in bradycardiac response to vagal stimulation, nicotine-induced seizure activity and anxiety. In order to identify genes that might be related to beta4-containing nAChRs activity, we compared the mRNA expression profiles of brains from beta4-/- and wild-type mice using Affymetrix U74Avr2 microarray. more...
