Project description:Our previous studies have shown that bone morphogenetic protein 2 (BMP2), a morphogen belonging to the TGFM-NM-2 superfamily, is markedly induced in human primary endometrial stromal cells (HESC) as they undergo differentiation in response to steroid hormones and cAMP. WNT4 is a downstream target of BMP2 regulation in these cells. To identify the common downstream targets of BMP2 and WNT4 in human endometrial stromal cells, we performed gene expression profling of human ensometrial stromal cell transduced with BMP2 or WNT4 adenovirus. Gene expression profiling revealed that FOXO1, a forkhead family transcription factor and a known regulator of HESC differentiation, is a common downstream mediator of both BMP2 and WNT4 signaling. These studies uncovered a linear pathway involving BMP2, WNT4, and FOXO1 that operates in human endometrium to critically control decidualization. Human endometrial stromal cells were transduced with recombinant adenovirus expressing BMP2, WNT4, or a negative control GFP at MOI 50:1 in 2 ml of culture medium. After transduction for 24 h, the viral particles were removed and the cells were treated with E+P for 3 days to induce decidualization (n=3 for each treatment), pooled total RNA from these cells was then hybridized to high density affymetrix microarrays according to the Affymetrix protocol (Human Genome HG-U133 A2.0 Array) .

Project description:Our previous studies have shown that C/EBPβ plays a critical role in human endometrial stromal decidualization. In order to identify the molecular pathways regulated by C/EBPβ during decidualization, we performed gene expression profiling using RNA isolated from normal and C/EBPβ-deficient human endometrial stromal cells. The microarray results revealed that several key regulators of stromal differentiation, such as BMP2, Wnt4, IL-11Rα and STAT3, operate downstream of C/EBPβ during decidualization. Further studies revealed that STAT3 is a direct target of C/EBPβ and plays an important role in cytokine signal during the decidualization process. Gene expression profiling, using STAT3-deficient HESCs, showed an extensive overlap of pathways downstream of STAT3 and C/EBPβ during stromal cell differentiation.

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:Our previous studies have shown that C/EBPM-NM-2 plays a critical role in human endometrial stromal decidualization. In order to identify the molecular pathways regulated by C/EBPM-NM-2 during decidualization, we performed gene expression profiling using RNA isolated from normal and C/EBPM-NM-2-deficient human endometrial stromal cells. The microarray results revealed that several key regulators of stromal differentiation, such as BMP2, Wnt4, IL-11RM-NM-1 and STAT3, operate downstream of C/EBPM-NM-2 during decidualization. Further studies revealed that STAT3 is a direct target of C/EBPM-NM-2 and plays an important role in cytokine signal during the decidualization process. Gene expression profiling, using STAT3-deficient HESCs, showed an extensive overlap of pathways downstream of STAT3 and C/EBPM-NM-2 during stromal cell differentiation. We employed a siRNA strategy to suppress C/EBPM-NM-2 or STAT3 mRNA expression in HESCs and then performed microarray analysis to identify its downstream target genes. Further, using a similar strategy, we focused on STAT3, a C/EBPM-NM-2 target gene, and identified the commone pathways downstream of both C/EBPM-NM-2 and STAT3.

Project description:In this study, we characterize the fusion protein produced by the EPC1-PHF1 translocation in Low Grade Endometrial Stromal Sarcoma (LG-ESS) and Ossifying FibroMyxoid Tumors (OFMT). We express the fusion protein and necessary controls in K562 Cells. The fusion protein assembles a mega-complex harboring both NuA4/TIP60 and PRC2 subunits and enzymatic activities and leads to mislocalization of chromatin marks in the genome, linked to aberrant gene expression.

Project description:Infertility and adverse gynecological outcomes such as preeclampsia and miscarriage represent significant female reproductive health concerns. The spatiotemporal expression of growth factors indicates that they play an important role in pregnancy. The goal of this study is to define the role of the ERBB family of growth factor receptors in endometrial function. Using conditional ablation in mice and siRNA in primary human endometrial stromal cells, we identified the epidermal growth factor receptor (Egfr) to be critical for endometrial function during early pregnancy. While ablation of Her2 or Erbb3 led to only a modest reduction in litter size, mice lacking Egfr expression are severely subfertile. Pregnancy demise occurred shortly after blastocyst implantation due to defects in decidualization including decreased proliferation, cell survival, differentiation and target gene expression. To place Egfr in a genetic regulatory hierarchy, transcriptome analyses was used to compare the gene signatures from mice with conditional ablation of Egfr, wingless-related MMTV integration site 4 (Wnt4) or boneless morphogenic protein 2 (Bmp2); revealing that not only are Bmp2 and Wnt4 key downstream effectors of Egfr, but they also regulate distinct physiological functions. In primary human endometrial stromal cells, marker gene expression, a novel high content image-based approach and phosphokinase array analysis were used to demonstrate that EGFR is a critical regulator of human decidualization. Furthermore, inhibition of EGFR signaling intermediaries WNK1 and AKT1S1, members identified in the kinase array and previously unreported to play a role in the endometrium, also attenuate decidualization. These results demonstrate that EGFR plays an integral role in establishing the cellular context necessary for successful pregnancy via the activation of intricate signaling and transcriptional networks, thereby providing valuable insight into potential therapeutic targets.
