Abstract 3051: mRNA and microRNA expression profiles integrated with drug sensitivities of the NCI-60 human cancer cell lines

Abstract

Abstract We present here new NCI-60 profiling studies of mRNA and miRNA expression using the 41,000-probe Agilent Whole Human Genome Oligo Microarray and the 15,000-feature Agilent Human miRNA Microarray V2. Expression levels were determined for ∼21,000 genes and 723 human miRNAs. The resulting data sets are freely available and searchable online at http://discover.nci.nih.gov in our CellMiner relational database package. The profiling included technical replicates, with six and eight cell lines assayed in quadruplicate for mRNA and miRNA, respectively. The remaining cell lines were assayed in duplicate. Our analysis indicates high reproducibility for both platforms and an essential biological similarity across the various cell types. The expression levels were integrated with our previously published 1,429-compound database of anticancer activity in the NCI screen. Large blocks of both mRNAs (∼2000) and miRNAs (∼200) with unidirectional correlation to ∼1300 drugs including 121 drugs with known mechanisms of action were identified. The data sets presented here will facilitate recognition of the groups of mRNAs, miRNAs and drugs that potentially affect and interact with one another.
