Human lung adenocarcinoma DNA copy number profiling


ABSTRACT: Lung adenocarcinoma’s genomic alterations exhibit vast variation. Lung adenocarcinoma also has previously described intrinsic gene expression subtypes (Hayes et al. 2006, PMID: 17075127). This study’s aim was to detect and validate subtype-specific alterations. A portion of these specimens were also assayed for genomewide transcription in GSE26939. 103 tumor samples and 30 normal samples were quantified for DNA copy number using Affymetrix SNP microarrays.

<h4>Background</h4>Lung adenocarcinoma (LAD) has extreme genetic variation among patients, which is currently not well understood, limiting progress in therapy development and research. LAD intrinsic molecular subtypes are a validated stratification of naturally-occurring gene expression patterns and encompass different functional pathways and patient outcomes. Patients may have incurred different mutations and alterations that led to the different subtypes. We hypothesized that the LAD molecula  ...[more]
