Description
We hypothesized that microarray analyses of whole blood gene expression would identify patterns of gene expression useful in the diagnosis for sacroidosis and identify inflammatory mediators relevant to the underlying pathophysiology.

Description
Natural killer (NK) cells play a critical role in early host defense to infected and transformed cells. Here we show that mice deficient in Eri1, a conserved 3’-to-5’ exoribonuclease that represses RNA interference, have a cell-intrinsic defect in NK cell development and maturation. Eri1–/– NK cells displayed delayed acquisition of Ly49 receptors in the bone marrow and a selective reduction in Ly49D and Ly49H activating receptors in the periphery. Eri1 was required for immune-mediated control of mouse cytomegalovirus (MCMV) infection. Ly49H+ NK cells deficient in Eri1 failed to expand efficiently during MCMV infection, and virus-specific responses were also diminished among Eri1–/– T cells. We identified miRNAs as the major endogenous small RNA target of Eri1 in mouse lymphocytes. Both NK and T cells deficient in Eri1 displayed a global, sequence-independent increase in miRNA abundance. Ectopic Eri1 expression rescued defective miRNA expression in mature Eri1–/– T cells. Thus, mouse Eri1 regulates miRNA homeostasis in lymphocytes and is required for normal NK cell development and anti-viral immunity. Overall design: Small RNA profiling from wildtype and Eri1-deficient mouse CD4+ T cells

Description
We collected airway epithelial brushings for microarray analysis from 42 asthmatics and two control groups 28 healthy subjects and 16 smokers. A subgroup of 32 asthmatics completed a randomized placebo-controlled trial of fluticasone propionate in which collection of brushings was repeated after 1 week of treatment.

Description
The growth of neural stem cells is strongly enhanced on myelin in vitro and in vivo. To identify the mechanisms associated with this phenome, we compared RNA expression from mouse E12 derived spinal cord cells on stimulation substrates (laminin and myelin) to permissive substrates (PDL). We identified Negr1 as mediator of the stimulatory effects of myelin. Overall design: Examination of transcripts in embryonic spinal cord cells stimulated by laminin and myelin substrates in vitro.

Description
Consider the problem of designing a panel of complex biomarkers to predict a patient's health or disease state when one can pair his or her current test sample, called a target sample, with the patient's previously acquired healthy sample, called a reference sample. As contrasted to a population averaged reference, this reference sample is individualized. Automated predictor algorithms that compare and contrast the paired samples to each other could result in a new generation of test panels that compare to a person's healthy reference to enhance predictive accuracy. This study develops such an individualized predictor and illustrates the added value of including the healthy reference for design of predictive gene expression panels. The objective is to predict each subject's state of infection, e.g., neither exposed nor infected, exposed but not infected, pre-acute phase of infection, acute phase of infection, post-acute phase of infection. Using gene microarray data collected in a large-scale serially sampled respiratory virus challenge study, we quantify the diagnostic advantage of pairing a person's baseline reference with his or her target sample.
