Meta-Analysis Evidence Of A Differential Risk Of The Fcrl3 -169t->C Polymorphism In White And East Asian Rheumatoid Arthritis Patients, Steven J. Schrodi, Begovich Ann, Chang Monica Jul 2007

Meta-Analysis Evidence Of A Differential Risk Of The Fcrl3 -169t->C Polymorphism In White And East Asian Rheumatoid Arthritis Patients, Steven J. Schrodi, Begovich Ann, Chang Monica

Association between a functional promoter polymorphism (rs7528684) in the Fc receptor-like gene, FCRL3, and rheumatoid arthritis (RA) has been observed in 3 independent Japanese case-control sample sets ([1][2]). Studies examining the role of this polymorphism in risk of RA in 9 independent white sample sets, however, have yielded conflicting results ([3-8]). Further, a large study of Korean subjects failed to demonstrate association of this single-nucleotide polymorphism (SNP) with RA ([9]). Although the precise function of FCRL3, which has strong structural homology with the classic Fc receptors, is unknown, the existing data are consistent with the hypothesis that it may influence …

Laser Capture Sampling And Analytical Issues In Proteomics, Howard Gutstein, Jeffrey S. Morris Jan 2007

Laser Capture Sampling And Analytical Issues In Proteomics, Howard Gutstein, Jeffrey S. Morris

Jeffrey S. Morris

Proteomics holds the promise of evaluating global changes in protein expression and post-translational modificaiton in response to environmental stimuli. However, difficulties in achieving cellular anatomic resolution and extracting specific types of proteins from cells have limited the efficacy of these techniques. Laser capture microdissection has provided a solution to the problem of anatomical resolution in tissues. New extraction methodologies have expanded the range of proteins identified in subsequent analyses. This review will examine the application of laser capture microdissection to proteomic tissue sampling, and subsequent extraction of these samples for differential expression analysis. Statistical and other quantitative issues important for …
