Data obtained from high-density oligonucleotide tiling arrays present new computational challenges for users. This chapter presents ACME (Algorithm for Capturing Microarray Enrichment), a computer program developed for the analysis of data obtained …
Sarcomas are a biologically complex group of tumors of mesenchymal origin. By using gene expression microarray analysis, we aimed to find clues into the cellular differentiation and oncogenic pathways active in these tumors as well as potential …
biomaRt is a new Bioconductor package that integrates BioMart data resources with data analysis software in Bioconductor. It can annotate a wide range of gene or gene product identifiers (e.g. Entrez-Gene and Affymetrix probe identifiers) with …
Genome-wide expression profiling of normal tissue may facilitate our understanding of the etiology of diseased organs and augment the development of new targeted therapeutics. Here, we have developed a high-density gene expression database of 18,927 …
Evidence for significant linkage in complexly inherited disorders usually necessitates independent, replicative studies. This study investigates the implications of including in the replicative studies families already used to suggest linkage in …
Genetic epidemiological studies have shown that genetic factors are important in the pathogenesis of the idiopathic inflammatory bowel diseases (IBD), Crohn disease (CD), and ulcerative colitis (UC). A genome screen in the United Kingdom found …
We have evaluated 23 different statistics, from a total of 10 popular software packages for model-free linkage analysis of nuclear-family data, by applying them to single-marker data simulated under several two-locus disease models. The statistics …
Hypertension is a significant risk factor for heart attack and stroke and represents a major public health burden because of its high prevalence (e.g. 15-20% of the European and American populations). Although blood pressure is known to have a strong …
Our analysis of GAW10 problem 2 data set consisted of linear regression analysis followed by linkage analysis. The linear regression analysis allowed some exploration of the relationships between the quantitative variables. Furthermore, it isolated …
We have analyzed the GAW10 data from several studies of bipolar affective disorder (BPAD) using the software packages SimIBD and SIMWALK2. SimIBD implements a simulation-based affected-pedigree-member (APM) statistic, called SimAPM, as well as an …
