Normal Lung + Lung adenocarcinoma microarray


ABSTRACT: Gene transcription in a set of 49 human primary lung adenocarcinomas and 9 normal lung tissue samples was examined using Affymetrix GeneChip technology. We aimed to investigate differential gene expression between the two tissue types. A total of 3,442 genes, called the set MAD, were found to be either up- or down-regulated by at least two fold between the two phenotypes. Genes assigned to a particular gene ontology term were found, in many cases, to be significantly unevenly distributed between the genes in and outside MAD. Terms that were overrepresented in MAD included functions directly implicated in cancer cell metabolism. Based on their functional roles and expression profiles, genes in MAD were grouped into likely co-regulated gene sets.
