JD Marotti, LC Collins, R Hu, RM Tamimi - Modern Pathology, 2010 - Elsevier
The expression of estrogen receptor-α (ER-α) and related genes has emerged as one of the
major determinants of molecular classification of invasive breast cancers. Expression of a
second ER, estrogen receptor-β (ER-β), has not been previously evaluated in a large
population-based study. Therefore, we examined ER-β expression in a large population of
women with breast cancer to assess its relationship to molecular categories of invasive
breast cancer. We constructed tissue microarrays from paraffin blocks of 3093 breast …
