In addition, ER-negative tumors were subdivided on the basis of their AR status [25], and cytokeratin 5/6 (CK5/6) staining was employed as a marker of basal-type tumors. Furthermore, we obtained IHC scores for PIP on the basis of the percentage and intensity of staining for this protein in each tumor (Figure?2, A and B). Next, we assessed the association of PIP expression with biomarkers and molecular subtypes. We observed that AR-positive tumors have a significantly higher PIP expression compared to AR negatives (P [http://www.selleckchem.com/products/bay-61-3606.html BAY-61-3606 purchase] tumors, PIP expression was associated with AR-positive status and was unrelated to CK5/6 staining ( Figure?2D). It is notable that PIP expression was not associated with either tumor [http://www.selleckchem.com/products/q-vd-oph.html Selleck QVDOph] size or grade in this cohort (P > .1). These findings suggest that PIP is widely expressed in luminal A, luminal B, and ER??/AR?+ (molecular apocrine) subtypes of breast cancer. Moreover, PIP expression is associated with AR and is present in both luminal and basal ER-negative tumors. To investigate the functional role of PIP in breast cancer, we carried out a nonbiased genomic approach to study the transcriptional signature of this gene using a microarray data set of 52 breast cancer cell lines [21]. To identify PIP coregulated genes, we first [http://en.wikipedia.org/wiki/Thymidine_kinase Thymidine kinase] calculated the Pearson CC for each gene expression in the data set with that of PIP and then obtained the list of genes that had Pearson CC values ��?0.5 (P
