Thirteen HER2 positive breast cancer cell lines were screened with 22 commercially available compounds, mainly targeting proteins in the ErbB2 signaling pathway, and the molecular mechanisms related to treatment response were sought. To search for response predictors, genomic and transcriptomic profiling, PIK3CA mutations and PTEN status were associated to the drug responses and several genes involved in the response of the compounds were identified. RNA from thirteen HER2 positive breast cancer cell lines was isolated and hybridized on Affymetrix arrays.
