Probe Selection and Expression Index Computation of Affymetrix Exon Arrays
BACKGROUND There is great current interest in developing microarray platforms for measuring mRNA abundance at both gene level and exon level. The Affymetrix Exon Array is a new high-density gene expression microarray platform, with over six million probes targeting all annotated and predicted exons in a genome. An important question for the analysis of exon array data is how to compute overall ...
متن کاملAnalysis of Affymetrix Exon Arrays
Exon arrays enable the monitoring of expression on a more fine-grained level than conventional 3' arrays. By targeting single exons alternative splicing events can be detected. However, the increased amount of data resulting from the denser coverage of the transcribed regions gives rise to new challenges in data analysis compared to 3' arrays. One must carefully decide which probes are consider...
متن کاملExpression profiling using affymetrix genechip probe arrays.
Large-scale microarray expression profiling studies have helped us to understand basic biological processes and to classify and predict the prognosis of cancers; they have also accelerated the identification of new drug targets. Affymetrix GeneChip probe arrays are high-density oligonucleotide microarrays that are available for many prokaryotic and eukaryotic species. Affymetrix human and mouse...
متن کاملIntegrating probe-level expression changes across generations of Affymetrix arrays
There is an urgent need for bioinformatic methods that allow integrative analysis of multiple microarray data sets. While previous studies have mainly concentrated on reproducibility of gene expression levels within or between different platforms, we propose a novel meta-analytic method that takes into account the vast amount of available probe-level information to combine the expression change...
متن کاملCross-hybridization modeling on Affymetrix exon arrays
MOTIVATION Microarray designs have become increasingly probe-rich, enabling targeting of specific features, such as individual exons or single nucleotide polymorphisms. These arrays have the potential to achieve quantitative high-throughput estimates of transcript abundances, but currently these estimates are affected by biases due to cross-hybridization, in which probes hybridize to off-target...
