A breakdown in stromal-epithelial interactions mediated by androgens is emerging as a key factor in prostate cancer (PCa) aetiology and progression. Currently however, we have limited knowledge of the mechanics of androgen and androgen receptor (AR) action in prostate stroma, or how dysfunction in that compartment contributes to the disease process.In this study, immunohistochemical analysis of 64 PCa samples revealed an inverse relationship between stro...

Studies into estrogen receptor alpha (ERα), progesterone receptor (PGR) and the androgen receptor (AR) involvement in breast, uterine and prostate cancers has provided considerable insight into the molecular actions these receptors, but have thus far focused on each receptor individually and alone in different cell types. Here, whole genome expression microarray analysis and ChIP-sequencing in ZR-75-1 breast cancer cells, in response to combinations of 17β-estradiol ...

One in 11 women develop breast cancer before the age of 75, and mortality is significant. Estrogens and progesterone (PROG) are mediators of breast cancer aetiology and progression, and are targets for both diagnostics and therapy. The actions of estrogens via estrogen receptor alpha (ERα) have been extensively studied, but the genomic actions of PROG via the progesterone receptor (PGR) are still not fully understood. This study investigates the genomic actions of PGR in ...
