Estrogen and progesterone receptor dynamics in patient-derived luminal breast cancer xenografts

(Submitter supplied) Progesterone receptors (PR) are co-expressed in over half of estrogen receptor (ER) positive breast cancers and predict positive response to endocrine therapy. PR can directly and globally modify ER action to attenuate tumor growth. However, whether this suppression occurs solely through PR-ER interactions remains unknown. We assessed tumor growth in two highly ER and PR positive breast cancer patient-derived xenografts (PDX) and found that natural and synthetic progestins potently antagonize the mitogenic effects of estrogens. more...

Genomic agonism and phenotypic antagonism between estrogen and progesterone receptors in breast cancer. [ChIP-seq]

(Submitter supplied) Transcriptomic changes and estrogen and progesterone receptor binding in multiple ER+/PR+ models (eight ER+/PR+ patient tumors, various T47Ds, ZR75) and multiple ER+/PR-negative models (four ER+/PR- patient tuumors, PR-deficient T47D and MCF7 cells) treated with various hormone combinations. Results: In isolation, estrogen and progestin act as genomic agonists by regulating the expression of common target genes in similar directions, but at different levels. more...

Tissue Specific Pathways for Estrogen Regulation of Ovarian Cancer Growth and Metastasis

(Submitter supplied) Menopausal estrogen (E2) replacement therapy increases the risk of estrogen receptor (ER)-positive epithelial ovarian cancers (EOC). Whether E2 is tumorigenic or promotes expansion of undiagnosed pre-existing disease is unknown. To determine E2 effects on tumor promotion, we developed an intraperitoneal mouse xenograft model using ZsGreen fluorescent ER- 2008 and ER+ PEO4 human EOC cells. Tumor growth was quantified by in vivo fluorescent imaging. more...

Maintenance of Hormone Responsiveness in Luminal Breast Cancers by Suppression of Notch

(Submitter supplied) Luminal breast cancers express estrogen (ER) and/or progesterone (PR) receptors and respond to hormone therapies. Basal-like “triple negative” (TN) cancers lack steroid receptors but are cytokeratin (CK) 5-positive and require chemotherapy. Here we show that over half of primary ER+PR+ breast cancers contain an ER–PR–CK5+ “luminobasal” subpopulation exceeding 1% of cells. Starting from ER+PR+ luminal cell lines, we generated novel lines with varying luminal to luminobasal-cell ratios and studied their molecular and biological properties. more...

Expression data from age-dichotomized ER+, N0 breast tumors

(Submitter supplied) Signaling pathways that converge on two different transcription factor complexes, NFκB and AP-1, have been identified in estrogen receptor (ER)-positive breast cancers resistant to the antiestrogen, tamoxifen. In this study, biomarkers co-ordinately up-regulated by NFKB and AP-1 with prognositic significance are identified in a largely TAM-treated set of ER+ node negative breast cancers. The prognostic value with respect to age is also investigated. more...

Comparison of MPA regulated gene expression profiles to those regulated by PROG, DHT, DEX

(Submitter supplied) Medroxyprogesterone acetate (MPA) is a progestin that can bind to and activate progesterone, androgen and glucocorticoid receptors. However, it is not known which receptor mediates MPA action in a cellular context where all three of these receptors are co-expressed and functional. This microarray experiment was performed to compare the transcriptomes induced by MPA and the cognate ligands for these receptors ie progesterone (PROG), 5a-dihydrotestosterone (DHT) and dexamethasone (DEX) in breast cancer cells to determine which was most similar to MPA.

Active FOXO1 is a Key Determinant of Isoform-Specific Progesterone Receptor Transactivation and Senescence Programming

(Submitter supplied) Progesterone promotes differentiation coupled to proliferation and pro-survival in the breast, but inhibits estrogen-driven growth in the reproductive tract and ovaries. Herein, it is demonstrated, using progesterone receptor (PR) isoform-specific ovarian cancer model systems, that PR-A and PR-B promote distinct gene expression profiles that differ from PR-driven genes in breast cancer cells. In ovarian cancer models, PR-A primarily regulates genes independently of progestin, while PR-B is the dominant ligand-dependent isoform. more...

Active FOXO1 is a Key Determinant of Isoform-Specific Progesterone Receptor Transactivation and Senescence Programming

(Submitter supplied) The progesterone receptor specific gene targets were investigated in ovarian and breast cancer cell lines where FOXO1 was found to be a primary factor that cooperates with PR to activate cellular senescence genes (including p21) specifically in ovarian cells. ABSTRACT: Progesterone promotes differentiation coupled to proliferation and pro-survival in the breast, but inhibits estrogen-driven growth in the reproductive tract and ovaries. more...
