BRCA1 and cancer: The aim of this study is to: 1) derive a basal type miRNA signature that is independent of grade, 2) compare miRNA expression between sporadic and BRCA1 basal cancers to derive a BRCA1 basal signature using formalin fixed paraffin embedded (FFPE) tissue and 3) interrogate via immunohistochemistry the expression of proteins, predicted by computer algorithms, to be regulated by BRCA1 basal specific miRNAs.
