Project description:RNA-seq analysis of uterine luminal epithelium at D4.5 indicates that epithelial PGRA and PGRB shares conseved pathways. Constitutive epithelial PGRA and PGRB disrupts the embryo implantation both through the suppressed FOXO1 signaling by excluding FOXO1 from the nuclear at the uterine epithelium. There are three layers of regulation. Firstly, PGRA and PGRB diminishes Lif transcription in uterine glands by blocking ESR1 binding at the Lif promoter at D3.5 which is critical for the FOXO1 nuclear expression at D4.5 through LIF/pSTAT3/FOXO1. Secondly, PGRA and PGRB directly suppres Foxo1 transcription at the uterine epithelium probably through direct binding at Foxo1 promoter. Thirdly, PGRA and PGRB promotes the Sgk1 transcription, the kinases that phosphorylate FOXO1 to translocate it into cytoplasma for degradation.

Project description:All except one cytokine of the Interleukin (IL-)6 family share glycoprotein (gp) 130 as the common b receptor chain. Whereas Interleukin (IL-)11 signal via the non-signaling IL-11 receptor (IL-11R) and gp130 homodimers, leukemia inhibitory factor (LIF) recruits gp130:LIF receptor (LIFR) heterodimers. Using IL-11 as a framework, we exchange the gp130 binding site III of IL-11 with the LIFR binding site III of LIF. The resulting synthetic cytokimera GIL-11 efficiently recruits the non-natural receptor signaling complex consisting of gp130, IL-11R and LIFR resulting in signal transduction and proliferation of factor-depending Ba/F3 cells. Besides LIF and IL-11, GIL-11 does not activate receptor complexes consisting of gp130:LIFR or gp130:IL-11R, respectively. Human GIL-11 shows cross-reactivity to mouse and rescued IL-6R deficient mice following partial hepatectomy, demonstrating gp130:IL-11R:LIFR signaling efficiently induced liver regeneration. With the development of the cytokimera GIL-11, we devise the functional assembly of the non-natural cytokine receptor complex of gp130:IL-11R:LIFR.

Project description:Embryo implantation into a receptive endometrium is tightly regulated by a variety of maternal factors, including cytokines, growth factors and transcription factors. Previous studies identified the leukaemia inhibitory factor (LIF), produced in uterine glands, as an essential factor for implantation. It was shown that LIF acts via its cell surface receptor to activate the transcription factor STAT3 in the uterine epithelial cells. However, the mechanisms via which STAT3 promotes uterine receptivity remain unknown. To address the molecular pathways regulated by STAT3 in the uterus, we created mice in which Stat3 gene is conditionally inactivated in uterine epithelium. These mutant mice are infertile due to implantation failure and exhibit a lack of embryo attachment to the luminal epithelium. Gene expression profiling of the epithelial tissue impaired in STAT3 activation revealed dysregulated expression of specific components of junctional complexes, including E-cadherin, M-NM-2-catenin, and claudins, which critically regulate epithelial cell polarity and embryo attachment. Additionally, mice lacking functional epithelial STAT3 showed markedly reduced stromal proliferation and differentiation, indicating that this transcription factor controls stromal function via a paracrine mechanism. The stromal defect arose from a drastic reduction in the production of several members of the epidermal growth factor (EGF) family in luminal epithelium of mutant uteri and consequent lack of activation of EGF receptor signaling and mitotic activity in the stromal cells. Collectively, our results uncovered intricate signaling networks operating downstream of STAT3 in uterine epithelium that regulate epithelial cell polarity, and stromal proliferation and differentiation, which are critical determinants of successful implantation. To identify the downstream targets of STAT3 in mouse uterine epithelial cells during pregnancy, we performed gene expression profling of mouse uterine epithelial cells on day 4 of pregnancy between Stat3 flox control and SW d/d mice. This led to the identification of several junctional molecules (Claudins and Catenins) that are negatively regulated by STAT3 at the time of implantation. Mouse uteirne epithelial cells were isolated from control and knockout mice on the morning of day 4 of pregnancy. (n=3 for each sample), pooled total RNA from these cells was then hybridized to high density affymetrix microarrays according to the Affymetrix protocol (Mouse Genome 430A 2.0 Array) .

Project description:Mammalian embryo development is dependent on the ability of the uterus to allow and support the implantation of the embryo. Here we demonstrate that ablation of Sox17 specifically in the uterine epithelium results in altered uterine epithelial cell proliferation, uterine gland development and embryo implantation. Uteri lacking Sox17 showed reduction in LIF and IHH signaling which are critical for embryo implantation. ChIP-seq analysis demonstrated that SOX17 binds to a region 19kb 5’ to the Ihh locus. In vivo deletion of this enhancer by the CRISPR-Cas technology reduced Ihh expression in uteri and altered proper endometrial epithelial-stromal interactions required for pregnancy leading to compromised fertility. The SOX17 binding peak at 19kb from the Ihh promoter also bound GATA2, FOXA2 and PGR. Bioinformatic analysis of regions overlapping SOX17, GATA2, FOXA2 and PGR bindings shows 737 genes with these common binding sites. This cluster of transcription factors identified in this enhancer region may represent a combination of regulatory elements essential for uterine epithelial gene expression and differentiation.

Project description:Postnatal development of the uterus involves specification of undifferentiated epithelium into uterine-type epithelium. That specification is regulated by stromal-epithelial interactions as well as intrinsic cell-specific transcription factors and gene regulatory networks. This study utilized mouse genetic models of Esr1 deletion, endometrial epithelial organoids (EEO), and organoid-stromal co-cultures to decipher the role of Esr1 in uterine epithelial development. Organoids derived from wild-type (WT) mice developed a normal single layer of columnar epithelium. In contrast, EEO from Esr1 null mice developed a multilayered stratified squamous type of epithelium with basal cells. Co-culturing Esr1 null epithelium with WT uterine stromal fibroblasts inhibited basal cell development. Of note, estrogen treatment of EEO-stromal co-cultures and Esr1 conditional knockout mice increased basal epithelial cell markers. Collectively, these findings suggest that Esr1 regulates uterine epithelium lineage plasticity and homeostasis and loss of ESR1 promotes altered luminal-to-basal differentiation driven by ESR1-mediated paracrine factors from the stroma.
