Project description:The homeobox gene HOXA10 plays a key role in endometrial differentiation during embryogenesis and is abundantly expressed in the adult endometrium and decidual cells. In the adult endometrium the expression of HOXA10 is regulated by estrogen and progesterone and the levels are highest in the decidualized cells. We have shown that HOXA10 is required in the endometrial cells to maintain the decidual cell phenotype. In this study we aimed to determine the molecular mechanisms by which HOXA10 maintains the decidual phenotype and the other roles it might have in decidual physiology. In vitro decidualized human endometrial stromal cells were knocked down for HOXA10 using siRNA and gene expression profiles of the scrambled and HOXA10 siRNA transfected cells were compared at 24, 48 and 72 h post transfection. Several genes having multiple functions were found to be differentially expressed. We postulate that HOXA10 is required by the decidual cells to support immune cell differentiation, trophoblast invasion and cellular remodeling. In vitro decidualized priamry cultures of human endometrial strmal cells transfected with a siRNA againts HOXA10 or a scrambled siRNA. Cells harvested at 24, 48 and 72 h post transfection.

Project description:Global m6A-modified mRNAs in undecidualized and decidualized primary human endometrial stromal cells were analyzed by using methylated RNA immunoprecipitation sequencing (MeRIP-seq)
Project description:We report the gene expression profile of primary human endometrial stromal cells treated for 48 hours with control non-targeting, PGR-targeting, or FOXO1-targeting siRNA prior to decidualization stimulus for 72 hours.
Project description:Expression profiles in decidualized and non-decidualized endometriotic cyst stromal cells (ECSCs) and normal endometrial stromal cells (NESCs)
Project description:To identify the miRNAs which regulate endometrial decidualization, we explored differentially expressed miRNAs between untreated NESCs (n=4) and decidualized NESCs (n=4) using miRNA microarray. The miRNA expression profiles of untreated NESCs and decidualized NESCs were obtained, then the miRNAs were filtered by signal intensity (50.0<, at least one out of 8 samples have values within range) and flags (at least 13% of cases have good flags). We established the criteria for regulated genes: ratio ≥2.0-fold for up-regulated genes and ratio ≤0.5 for down-regulated genes.
Project description:Progesterone regulated genes in the endometrial stromal compartment were studied in proven fertile women using laser dissection capture microscopy followed by microarray. Endometrial biopsies were obtained from women before (control group, n=9) and after (study group, n=9) treatment with mifepristone. Stromal cells were isolated by Laser-capture microdissection and RNA was extracted. The gene expression was analyzed by microarray and reconfirmed by real-time PCR.
Project description:The goal of the study was to assess transcriptome profile of non-decidualized (non-DE) and decidualized (DE) endometrial stromal cells (eSCs) obtained from women with polycystic ovary syndrome (PCOS, eSCPCOS) and non-PCOS controls (eSCCtrl) in response to short-term estradiol (E2) and/or progesterone (P4) exposure with or without dihydrotestosterone (DHT). The eSCs used for RNA-sequencing (RNA-seq) were isolated from proliferative stage endometrium from women with PCOS (diagnosed based on Rotterdam criteria) and non-PCOS controls (n=6 per group). The same eSCs were used for in vitro validation by immunofluorescence (IF; n=3/group). Tissue validation by immunohistochemistry (IHC) was done using whole biopsy formalin-fixed proliferative (PE) and secretory phase (SE) endometrial samples (IHC; n=6/cycle phase/group). Our data provided the observation that Decidualized eSCPCOS display a distinct transcriptome profile, especially in the presence of DHT.
