A BRCA1 Deficient-Like Signature is Enriched in Breast Cancer Brain Metastases

(Submitter supplied) Purpose: There is an unmet clinical need for biomarkers to identify breast cancer patients who are at increased risk of developing brain metastases. The objective is to identify gene signatures and biological pathways associated with HER2+ brain metastasis. Experimental Design: Gene expression of 19 HER2+ breast cancer brain metastases was compared with HER2+ nonmetastatic primary tumors. Gene Set Enrichment Analysis was used to identify a signature, which was evaluated for correlation with BRCA1 mutation status and clinical outcome using published microarray datasets and for correlation with pharmacological inhibition by a PARP inhibitor and temozolomide using published microarray datasets of breast cancer cell lines. more...

Human epidermal growth factor receptor 2-positive breast cancer brain metastases

Analysis of HER2+ breast cancer brain metastasis specimens and HER2+ nonmetastatic primary breast tumors. Samples were matched for patient age upon primary tumor detection and ER status of primary tumor. Results provide insight into the molecular basis of HER2+ breast cancer outgrowth in the brain.

[U133_X3P] Affymetrix Human X3P Array

(Submitter supplied) Affymetrix submissions are typically submitted to GEO using the GEOarchive method described at http://www.ncbi.nlm.nih.gov/projects/geo/info/geo_affy.html The GeneChip X3P Array was designed specifically for whole-genome expression profiling of formalin-fixed, paraffin-embedded (FFPE) samples, and is now available via the GeneChip Made-to-Order program. Resulting from a collaboration between Affymetrix and Arcturus, this array is optimized as part of a system solution together with the Paradise Reagent System from Arcturus for expression analysis of FFPE samples. more...
