Detecting Sources of Transcriptional Heterogeneity in Large-Scale RNA-Seq Data Sets.

Abstract excerpt

Gene expression levels are dynamic molecular phenotypes that respond to biological, environmental, and technical perturbations. Here we use a novel replicate-classifier approach for discovering transcriptional signatures and apply it to the Genotype-Tissue Expression data set. We identified many factors contributing to expression heterogeneity, such as collection center and ischemia time, and our approach of...
