Project description:GOLPH3 was silenced in human endometrial stromal cells (hESCs), and the transcriptome data (RNA-seq) by GOLPH3 knockdown (siGOLPH3) was obtained by high-throughput sequencing technology,
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:To identify the molecular pathway regulated by Scribble (SCRIB) in primary hunan endometrial stromal cells (ESCs) decidualization, high-throughput RNA-seq was performed to analyze the transcriptome profile in si-Ctrl or si-SCRIB transfected decidualized ESCs (dESCs).
Project description:We report the application of an improved assay for transposase-accessible chromatin with high-throughput sequencing in profiling changes of chromatin openning state in senescent human stromal cells. By obtaining over four billion bases of sequence from Tn5 transposase-processed chromosome DNAs, we generated genome-wide chromatin-state maps of human primary stromal cells (with a starting cell number of 50,000). This study provides a framework for the application of ATAC-Seq technique towards spatiotemporal chromatin configuration of human stromal cells upon DNA damage-induced senescence.
Project description:To identify differentially expressed genes (DEGs) and molecular pathways in eutopic endometrial stroma cells (EuESCs) from adenomyosis patients and provide a new insight into disease mechanisms at transcriptome level.Gene expression profiling of normal endometrial stromal cells (N-ESCs) and adenomyotic eutopic endometrial stroma cells (A-EuESCs) were analyzed by using RNA-sequencing.
Project description:The zinc-finger transcription factor GATA2 has been shown to be important for endometrial stromal cell decidualization in early pregnancy in mice and humans. Progesterone and its receptor PGR is also critical during decidualization but its interaction with GATA2 in regulating genes and pathways necessary for decidualization in human endometrium are unclear. Human endometrial stromal cells were isolated from 5 premenopausal women for primary cell culture. The cells underwent in vitro decidualization (IVD) or vehicle (Veh) treatment for 10 days. RNA-sequencing (RNA-seq) was performed to compare gene expression profiles (n=3) and chromatin immunoprecipitation followed by sequencing (ChIP-seq) using an antibody against GATA2 (n=2) was performed to examine binding to target genes in the Veh and IVD cells. A public PGR ChIP-seq dataset (GSE69539) was mined to identify PGR-binding regions in IVD-treated human endometrial cells.

Project description:Endometrial estrogen receptor-α (ESR1) is indispensable for epithelial and stromal proliferation and differentiation during decidualization, yet the gene targets of estradiol (E2) / ESR1 in human stromal cells and associated mechanisms remain unknown. In this study, we characterized global E2-ESR1‒dependent transcriptomic changes and ESR1 recruitment to chromatin. Human endometrial stromal cells were isolated from 4 premenopausal women for primary cell culture. Genome-wide RNA expression by RNA-sequencing was compared in endometrial stromal cells with or without siRNA knockdown of ESR1 in the presence or absence of E2 (n=2). Genome-wide recruitment of ESR1 to chromatin was assessed by chromatin immunoprecipitation sequencing using an antibody against ESR1 was performed to examine binding to target genes (n=1).
