caArray_geral-00143: An estrogen receptor-negative breast cancer subset characterized by a hormonally regulated transcriptional program and response to androgen

Clinical heterogeneity of esrtrogen receptor-negative, progesterone receptor-negative [ER(-)/PR(-)] breast cancer (BC) suggests biological heterogeneity. We performed gene expression analysis of primary BCs and BC cell lines to identify the underlying biology of ER(-)/PR(-) disease, define subsets, and identify potential therapeutic targets. geral-00143 Assay Type: Gene Expression Provider: Affymetrix Array Designs: HG-U133A Organism: Homo sapiens (ncbitax) Material Types: cRNA, cell, OrganismPart, whole_organism, total_RNA Disease States: breast carcinomas
