Project description:To clarify mineralcorticoid receptor and glucocorticoid receptor-dependent gene networks in decidualizing human endometrial stromal cells. Genome-wide microarray analysis was performed on primary cultures established from 4 different patients. Stromal cell cultures were subjected to either GR or MR siRNA knockdown or control non-targeting siRNA then decidualized for four days before harvesting and RNA extraction for microarray analysis.

Project description:Uterine glands and, by inference, their secretions impact uterine receptivity, blastocyst implantation, stromal cell decidualization, and placental development. Changes in gland function across the menstrual cycle are impacted by steroid hormones, estrogen and progesterone, as well as stroma-derived factors. Using an endometrial epithelial organoid (EEO) system, transcriptome and proteome analyses identified distinct responses of the EEO to steroid hormones and prostaglandin E2 (PGE2). Notably, steroid hormones and PGE2 modulated the basolateral secretion of EEO proteins, where cystatin C (CST3) was significantly increased by progesterone and PGE2. CST3 treatment of decidualizing stromal cells significantly decreased the decidualization markers PRL and IGFBP1. The attenuation of stromal cell decidualization via CST3 suggests a role for uterine gland-derived proteins in controlling the extent of decidualization. These findings provide evidence that uterine gland-derived factors directly impact stromal cell decidualization, which has strong implications for better understanding pregnancy establishment and female fertility in humans.

Project description:Steroid hormone receptors are simultaneously active in many tissues and capable of altering each other's function. Estrogen receptor ɑ (ER) and glucocorticoid receptor (GR) are expressed in the uterus and their ligands have opposing effects on uterine growth. In endometrial tumors expressing high levels of ER, we surprisingly found that expression of GR is associated with poor prognosis. Dexamethasone reduced normal uterine growth in vivo; however, this growth inhibition was abolished in estrogen-induced endometrial hyperplasia. We observed low genomic binding site overlap when ER and GR are induced with their respective ligands; however, upon simultaneous induction they co-occupy more sites. GR binding is significantly altered by estradiol with GR recruited to ER bound loci that become more accessible upon estradiol induction. Gene expression responses to co-treatment were more similar to estradiol, but with novel regulated genes. Our results suggest phenotypic and molecular interplay between ER and GR in endometrial cancer.

Project description:The glucocorticoid receptor (GR) is a crucial drug target in multiple myeloma as its activation with glucocorticoids effectively triggers myeloma cell death. However, as high-dose glucocorticoids are also associated with deleterious side effects, novel approaches are urgently needed to improve GR’s action in myeloma. Here we reveal a functional crosstalk between GR and the mineralocorticoid receptor (MR) that culminates in improved myeloma cell killing. We show that the GR agonist Dexamethasone (Dex) downregulates MR levels in a GR-dependent way in myeloma cells. Co-treatment of Dex with the MR antagonist Spironolactone (Spi) enhances Dex-induced cell killing in primary, newly diagnosed GC-sensitive myeloma cells, while in a relapsed GC-resistant setting, Spi alone induces distinct myeloma cell killing. On a mechanistic level, we find that a GR-MR crosstalk is arising from an endogenous interaction between GR and MR in myeloma cells. Quantitative dimerization assays show that Spi reduces Dex-induced GR-MR heterodimerization and completely abolishes Dex-induced MR MR homodimerization but leaves GR-GR homodimerization intact. Unbiased transcriptomics further reveals that c-myc and many of its target genes are downregulated most by Dex and Spi combined, while proteomics analyses identify that several metabolic hallmarks are modulated most by this combination treatment. Finally, we identified a subset of Dex+Spi downregulated genes and proteins that may predict prognosis in the CoMMpass patient cohort. Our study demonstrates that GR-MR crosstalk is therapeutically relevant in myeloma as it provides novel strategies towards glucocorticoid-based dose-reduction.

Project description:Proper decidualization is vital in preparation for a potential embryo receptivity, placentation, menstrual health and subsequent endometrial regeneration. Given the importance of extracellular vesicles (EVs) in intercellular communication, and recently in embryo implantation and indicators of menstrual cycle and fertility, we investigated their role during decidualization. Overall, this study provides an insight into distinct variation in sEV composition depending upon the level of decidualization of endometrial stromal cells, with the signaling potential to coordinate endometrial health ranging from embryo implantation, facilitating placentation and subsequent endometrial regeneration.

Project description:Inappropriate excess of the steroid hormone aldosterone, which is a mineralocorticoid receptor (MR) agonist, is associated with increased inflammation and risk of cardiovascular disease. MR antagonists are cardioprotective and antiinflammatory in vivo, and evidence suggests that they mediate these effects in part by aldosterone- independent mechanisms. We used affymetrix to characterize the effect of Mineralocorticoid Receptor deletion on macrophage transcriptional profile, and identify its requirement in normal glucocorticoid signalling. We isolated mouse peritoneal macrophages from Myeloid MRKO mice and Floxed Controls, cultured in the presence or absence of corticosterone. RNA was extracted for Affymetrix cDNA hybridization. Each sample was pooled from experiments performed in triplicate.
