Gene expression profiles of decidualized human endometrial stromal cells knockdown for HOXA10

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.

Transcription profiling of human endometrial stromal cells treated with human trophoblasts vs. control, sampled at multiple time points to investigate stromal cell response to paracrine signals from the trophoblast

Project description:During the invasive phase of implantation, trophoblasts and maternal decidual stromal cells secrete products that regulate trophoblast differentiation and migration into the maternal endometrium. Paracrine interactions between the extravillous trophoblast and the maternal decidua are important for successful embryonic implantation, including establishing the placental vasculature, anchoring the placenta to the uterine wall, and promoting immuno-acceptance of the fetal allograph. Global cross-talk between the trophoblast and the decidua has not been elucidated to date, and the current study used a functional genomics approach to investigate these paracrine interactions. Human endometrial stromal cells were decidualized with progesterone and were further treated with conditioned media (CM) from human trophoblasts (TCM) or, as a control, with conditioned media (CCM) from non-decidualized stromal cells for 0, 3 and 12 hr. Total RNA was isolated and processed for analysis on whole genome, high density oligonucleotide arrays, containing 54,600 genes. Our data demonstrate a significant induction of pro-inflammatory cytokines and chemokines, as well as angiogenic/static factors in decidualized endometrial stromal cells in response to trophoblast-secreted products. The data suggest that the trophoblast acts to alter the local immune environment of the decidua to facilitate the process of implantation and assure an enriched cytokine/chemokine environment, while limiting mitotic activity of the stromal cells during the invasive phase of implantation.

Knockdown of mineralocorticoid receptor or glucocorticoid receptor on human endometrial stromal cells and decidualization

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.

Spatial targeting of the prostaglandin receptor EP2 is essential in driving a sustained PGE2-mediated cAMP signaling in the human endometrium

Project description:In a process known as decidualization, progesterone signaling in the human endometrium converges with local cAMP production to drive morphometric and transcriptomic changes that prepare the endometrium for pregnancy. The source of cAMP has been contentious but the prostaglandin PGE2 signaling through EP2, its G-protein coupled receptor, remains a strong candidate. Cells often employ additional receptor regulation to diversify and prolong the cAMP signal and its down-steam effects, most notably through internalization and trafficking of receptors through endosomes. Here, we decidualized cultured endometrial stromal cells for 4-days with PGE2 and MPA (a progestin) and compared transcriptomic profiles with those depleted of either GIPC or APPL1, adaptor proteins involved in trafficking and recycling of EP2 respectively.

Expression data of differentially regulated genes in ESR1 depleted human endometrial stromal cells during differentiation.

Project description:Estrogen and progesterone are important regulators of human endometrial differentiation. These steroid hormones act, at least in part, through their nucelar receptors. Role of estrogen receptor alpha (ESR1) during human endometrial differentiation is still unclear. We used microarray analysis to detail the gene expression regulated by ESR1 during differentiation of human endometrial stromal cells.
