Project description:gene expression at 6h of differentiation of Human endometrial stromal cell expressing either or both of PRA and PRB Endogenous PGR expression is silenced with siRNA mediated knockdown. Then, cells are transduced with adenovirus exressing flag tagged PRA or flag tagged PRB. Human endometrial stromal cell expressing one or both isoforms are treated with differentiation cocktail for 6h.

Project description:We report the genome-wide binding sites of PGR-A and PGR-B at 2h of in vitro differentiation of human endometrial stromal cells that express either PGR-A or PGR-B. Progesterone, acting through the progesterone receptors (PGRs), is one of the most critical regulators of endometrial differentiation, known as decidualization, which is a key step toward the establishment of pregnancy. Yet a long-standing unresolved issue in uterine biology is the precise roles played by the major PGR isoforms, PGR-A and PGR-B, during decidualization in the human. Our approach, expressing PGR-A and PGR-B individually after silencing endogenous PGRs in human endometrial stromal cells (HESC), enabled the analysis of the roles of these isoforms separately as well as jointly by ChIP-seq and gene-expression analysis. In order to study the cistromes of PGR-A and PGR-B at 2h of in vitro differentiation of human endometrial stromal cells, we generated primary cultures of human endometrial stromal cells expressing flag tagged PGR-A and PGR-B individually after silencing endogenous PGRs. Input DNA was used as the reference sample.

Project description:The progesterone receptor isoforms PRA and PRB are implicated in breast cancer development and metastasis. Expression ratio PRA/PRB is imbalanced in such cancers under the influence of MAPK-dependent extracellular stimuli that strongly impact progesterone-responsiveM- transcriptional regulation. In order to determine the isoform-specific regulated genes M- in a metastatic cancer cell, we established the iPRAB cell line derived from MDA-MB-231 mammary cancer cells (ER-, PR-). This cell lineM- conditionally expressed PRA and/or PRB under the control of RSL1 and doxycycline (Dox) non-steroid ligands, respectively, in a dose-dependent manner. The bi-inducible expression system was generated using a combination of the Rheoswitch (NE Biolabs) and T-Rex (Invitrogen) vector systems as described in the article. We investigated the transcriptomes obtained in cells treated by either RSL1 (for PRA), or Dox (for PRB), or RSL1 + Dox (for PRA + PRB) for 24 h and then by either 10 nM progesterone (+) or vehicle (-) for 6 h. Control experiments were obtained from cells grown in the absence of RSL1, doxycycline and in the presence of progesterone (O+) or vehicle (O-). Experimental conditions of PRA/PRB expression ratio were ranged from 0.1 to 10, and the maximum expression of a given isoform was set to 300 fmol per mg proteins following 24 h induction. After removing redundant probes and pseudogens, the processed data identified 1014 distinct regulated genes subdivised in 3 classes : genes responding either only to unliganded PR isoforms (-), or only to liganded (+) or to both conditions (mixed M-1). Each classe was subdivided according to isoform specificity criteria (A, B, AB, A&B, A&AB, B&AB, A&B&AB) leading to define 3X7 clusters of genes per classe. Each subset was then further analyzed by complete hierarchical clustering through up or down-regulation criteria. These data indicated that PR target genes selectivity is highly dependent of PRA/PRB expression ratio as well as ligand status and highlight the major impact of PR on transcriptional regulation of genes involved in breast cancer and metastasis.

Project description:Progesterone receptor (PR) isoforms, PRA and PRB, both progesterone-independent and dependent modulated the biology of breast cancer cells. The different phenotypes in breast cancer mediated by PRA and PRB could due to the differences of their structures, leading to the distinct protein interacting partners and downstream signaling events of each receptor. Here, we constructed Tet-inducible HA-tagged PRA or HA-tagged PRB in T47DC42 breast cancer cells. We performed affinity purification coupled with SILAC mass spectrometry technique to comprehensively study PRA and PRB interacting partners in both liganded and unliganded conditions. To validate our findings, we applied both forward and reverse SILAC to effectively minimize experimental errors. These datasets will be useful in investigating PRA- and PRB-specific molecular mechanisms and can potentially be used as a database for subsequent experiments to identify novel PRA and PRB interacting proteins that differentially mediated different biological functions in breast cancer cells.

Project description:Progesterone receptor (PR) is expressed from a single gene as two isoforms, PRA and PRB. In normal breast human tissue, PRA and PRB are expressed in equimolar ratios, but isoform ratio is altered during malignant progression, usually leading to high PRA:PRB ratios. We took advantage of a transgenic mouse model where PRA isoform is predominant (PRA transgenics) and identified the key transcriptional events and associated pathways underlying the preneoplastic phenotype in mammary glands of PRA transgenics as compared with normal wild-type littermates.

Project description:Every year more than 42,000 women die of endometrial cancer, mainly due to recurrent or metastatic disease. The presence of tumor infiltrating lymphocytes (TILs) as well as progesterone receptor (PR) positivity has been correlated with improved prognosis. This study describes two mechanisms by which progesterone inhibits metastatic spread of endometrial cancer: by stimulating T-cell infiltration and by inhibiting epithelial-to-mesenchymal cell transition (EMT). Paraffin sections from patients with (n=9) or without (n=10) progressive endometrial cancer (recurrent or metastatic disease) were assessed for the presence of CD4+ (helper), CD8+ (cytotoxic) and Foxp3+ (regulatory) T-lymphocytes and PR expression. Progressive disease was observed to be associated with significant loss of TILs and loss of PR expression. Frozen tumor samples, used for genome-wide expression analysis, showed significant regulation of pathways involved in immunosurveillance, EMT and metastasis. For a number of genes, such as CXCL14, DKK1, DKK4 and WIF1, quantitive RT-PCR was performed to verify down regulation in progressive disease. To corroborate the role of progesterone in regulating invasion, Ishikawa (IK) endometrial cancer cell lines stably transfected with PRA (IKPRA), PRB (IKPRB) and PRA+PRB (IKPRAB) were cultured in the presence/absence of progesterone (MPA) and used for genome-wide expression analysis, Boyden- and wound healing migration assays, and IHC for known EMT makers. IKPRB and IKPRAB cell lines showed MPA induced inhibition of migration and loss of the mesenchymal marker vimentin at the invasive front of the wound healing assay. Furthermore, pathway analysis of significantly MPA-regulated genes showed significant down regulation of important pathways involved in EMT, immunesuppression and metastasis: such as IL6-, TGF-β and Wnt/β-catenin signalling. Intact progesterone signaling in non-progressive endometrial cancer seems to be an important factor stimulating immunosurveillance and inhibiting transition from an epithelial to a more mesenchymal, more invasive phenotype. The PRA- and PRB-expressing Ishikawa endometrial cancer cell line (IKPRAB36) was cultured for 48h in the absence or presence of 1nM MPA (n = 3). The RNA was isolated and used for hybridization on Affymetrix microarrays. Cells cultured in the presence of MPA were compared with cells cultured in the absence of MPA.

From 4 non-progressive and 4 progressive patients, snap-frozen endometrial cancer tumor specimens were used for microarray analysis. Gene expression data of progressive disease was compared with non-progressive disease.
