Project description:In this study, we sought to understand the effects of excess adipose on the benign endometrium. We used a physiologic in vitro coculture system consisting of multicellular organoids of the benign human endometrium and adipose spheroids in the presence of estradiol, progesterone, and testosterone to mimic the menstrual cycle. Gene expression analysis of endometrial organoids under high adiposity conditions revealed downregulation of genes normally expressed in secretory endometrium, suggestive of an altered progesterone response. Genes associated with ion homeostasis and detoxification of reactive oxygen species were also downregulated, including the metallothionein (MT) family of genes. We demonstrated that MT gene expression in endometrial organoids was regulated by progesterone specifically in the epithelial cells, and that progesterone receptor is recruited to the promoters of MT genes in endometrial epithelial cells. We illustrated the impact of MT dysregulation by silencing MT genes in endometrial epithelial cells, resulting in increased DNA damage. Our results reveal that exposing the endometrium to high adiposity can compromise the protective effects of progesterone, dysregulate MT genes in the endometrial epithelium, and leave the endometrium vulnerable to ROS-induced DNA damage.

Project description:H9 Pluripotent Stem Cells (PSC) were differentiated to Endometrial Stromal Fibroblasts (PSC-ESF) in monolayer over the course of 12 days. Gene expression was measured at day 0, day 4, day 8, and day 12 of differentiation. At day 12, PSC-ESF were dissociated from monolayer culture for co-culture with endometrial epithelial organoids established from term decidua. Gene expression was also measured after 26 days in co-culture (Cycle 1, vehicle or cAMP/progesterone/estradiol) and after 52 days in co-culture (Cycle 2, vehicle or cAMP/progesterone/estradiol)

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. 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.

Project description:For pregnancy to be established, uterine cells respond to the ovarian hormones, estrogen, and progesterone, via their nuclear receptors, the estrogen receptor (ESR1) and progesterone receptor (PGR). ESR1 and PGR regulate genes by binding chromatin at genes and at distal enhancer regions, which interact via dynamic 3-dimensional chromatin structures. Endometrial epithelial cells are the initial site of embryo attachment and invasion, and thus understanding the processes that yield their receptive state is important. Here, we cultured and treated organoids derived from human epithelial cells, isolated from endometrial biopsies, with estrogen and progesterone and evaluated their transcriptional profiles, their PGR cistrome, and their chromatin conformation. Progesterone attenuated estrogen-dependent gene responses but otherwise minimally impacted the organoid transcriptome. PGR ChIPseq peaks were co-localized with previously described organoid ESR1 peaks, and most PGR and ESR1 peaks were in B (inactive) compartment regions of chromatin. Significantly more ESR1 peaks were assigned to estrogen-regulated genes by considering chromatin loops identified using HiC than were identified using ESR1 peak location relative to closest genes. Overall, the organoids model allowed a definition of the chromatin regulatory components governing hormone responsiveness.

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.
