(Submitter supplied) Purpose: Previous studies of breast tissue gene expression have demonstrated that the extratumoral microenvironment has substantial variability across individuals, some of which can be attributed to epidemiologic factors. To evaluate how mammographic density (MD) and breast tissue composition relate to extratumoral microenvironment gene expression, we used data on 121 breast cancer patients from the population-based Polish Women’s Breast Cancer Study.Design: Breast cancer cases were classified based on a previously reported, biologically-defined extratumoral gene expression signature with two subtypes: an Active subtype, which is associated with high expression of genes related to fibrosis and wound response, and an Inactive subtype, which has high expression of cellular adhesion genes. more...

(Submitter supplied) This multi-pack (4X44K) formatted microarray represents a compiled view of the human genome as it is understood today. The sequence information used to design this product was derived from a broad survey of well known sources such as RefSeq, Goldenpath, Ensembl, Unigene and others. The resulting view of the human genome covers 41K unique genes and transcripts which have been verified and optimized by alignment to the human genome assembly and by Agilent's Empirical Validation process. more...
