Project description:The ability of trophectodermal cells (outer layer of the embryo) to attach to the endometrial cells and subsequently invade the underlying matrix are critical stages of embryo implantation during successful pregnancy establishment. Extracellular vesicles (EVs) have been implicated in embryo-maternal crosstalk, that reprogram endometrial cells towards a pro-implantation signature and phenotype. However, challenges associated with EV yield and direct loading of biomolecules limits their therapeutic potential. We have previously established generation of cell-derived nanovesicles (NVs) from human trophectodermal cells (hTSCs) and their capacity to reprogram endometrial cells to enhance adhesion and blastocyst outgrowth. Here, we developed a rapid NV loading strategy to encapsulate potent implantation molecules such as HB-EGF (NVHBEGF). We show these loaded NVs upon uptake to low-receptive endometrial HEC1A cells elicit EGFR-downstream pathways and enhance target cell attachment and invasion in an EGF-signalling dependent manner. This phosphoproteomics and proteomics approach reveals that NVHBEGF regulate short-term signalling (e.g., ERBB/EGFR signalling) and long-term reprogramming capabilities on endometrial cells, and demonstrate their functional regulation on trophectodermal-endometrial interactions and trophectodermal invasion. This proof-of-concept study demonstrate feasibility in enhancing the potency of NVs in the context of embryo attachment and establishment.

Project description:Forkhead box A2 (FOXA2) is a critical regulator of endometrial gland development in mice. In the adult mouse uterus, FOXA2 is expressed solely in the GE cells of the endometrium. Conditional deletion of Foxa2 after birth in the uterus, using the progesterone receptor Cre mouse (PgrCre), impeded gland development, thereby rendering the adult mouse infertile due to defects in blastocyst implantation stemming from a lack of endometrial glands and their secretions. As a first step to begin understanding the FOXA2 function in the endometrial glands of the uterus, genome-wide investigation of in vivo FOXA2 and RNA polymerase II (POL2) binding target regions in the neonatal and adult uterus was determined by chromatin immunoprecipitation followed by massively parallel sequencing (ChIP-Seq). In order to determine the transcriptional regulatory networks mediating FOXA2 regulation of endometrial gland development and function, chromatin immunoprecipitation and massively parallel sequencing (ChIP-Seq) was used to create a genome-wide profile of in vivo FOXA2-binding sites in the developing (PD 12) and adult (DOPP 2.5 and 3.5) mouse uterus.

Project description:The identification of target genes at genome-wide association study (GWAS) loci is a major obstacle for GWAS follow-up. To identify candidate target genes at the 16 known endometrial cancer GWAS risk loci, we performed HiChIP chromatin looping analysis of endometrial cell lines. To enrich for enhancer-promoter interactions, a mechanism through which GWAS variation may target genes, we captured loops associated with H3K27Ac histone, characteristic of promoters and enhancers. Analysis of HiChIP loops contacting promoters revealed enrichment for endometrial cancer GWAS heritability and intersection with endometrial cancer risk variation identified 103 HiChIP target genes at 13 risk loci. Expression of four HiChIP target genes (SNX11, SRP14, HOXB2 and BCL11A) was associated with risk variation, providing further evidence for their regulation. Network analysis functionally prioritized a set of proteins that interact with those encoded by HiChIP target genes, and this set was enriched for pan-cancer and endometrial cancer drivers. Lastly, HiChIP target genes and prioritized interacting proteins were over-represented in pathways related to endometrial cancer development. In summary, we have generated the first global chromatin looping data from endometrial cells, enabling analysis of all known endometrial cancer risk loci and identifying biologically relevant candidate target genes.

Project description:Endometriosis is a prevalent health condition in women of reproductive age characterized by ectopic growth of endometrial tissue in the extrauterine environment. Thorough understanding of the molecular mechanisms underlying the disease are still lacking and incomplete. We dissect eutopic and ectopic endometrial primary stromal cell proteomes to a depth of nearly 6900 proteins using quantitative mass-spectrometry with a spike-in SILAC standard. Acquired data reveal metabolic reprogramming of ectopic stromal cells of endometriosis with extensive upregulation of glycolysis and down-regulation of oxidative respiration – a wide-spread metabolic phenotype previously described in many cancers. Our results also underlie other molecular changes of ectopic endometriotic stromal cells indicating reduced apoptotic potential, increased cellular adhesiveness/invasiveness and altered immune function. The changes related to metabolism are additionally reflected by attenuated aerobic respiration of ectopic endometrial stromal cells measured by live cell oximetry and by altered mRNA levels. These comprehensive proteomics data refine the current understanding of endometriosis presenting potential new avenues for therapies.

Project description:Preimplantational estrogen exposure to pregnant gilts has been associated with implantation failure, embryonic losses and changes in endometrial mRNA expression. Small non-coding RNAs (ncRNA), especially miRNAs, play a key role in regulation of gene expression. Effects of estrogens on endometrial microRNAs (miRNA), however, have not been investigated in this context so far. Thus, we studied the influence of estradiol-17β (E2) on the endometrial expression profile of miRNAs in the pig at gestational day 10. E2 administered early during pregnancy resulted in significantly higher endometrial estrogen concentrations even at a low dose, but did not disrupt the expression profile of endometrial miRNAs.

Project description:Traditional surgery plus radiotherapy or chemotherapy, existing targeted therapies failed to significantly improve the survival rate of recurrent endometrial cancer, so suggesting that mechanism of recurrence and progression that modulates in endometrial cancer is clinically important. Here, we show that GPER(G protein-coupled estrogen receptor 1) was binded to AMF, and the complex were translocation form plasma to cytoplasmic. Mechanistic investigations elucidated that interaction of AMF with GPER triggers phosphoinositide-3-kinase (PI3K) signaling activating and accelerating the ability of endometrial cancer cells growth. Furthermore, we found that AMF may contribute to GPER-mediated endometrial cancer progression using animal experiments and human histological experiments which be consistent with the above conclusions. On the basis of these evidences including invivo and invitro, our findings suggest that AMF–GPER interaction might be novel key molecular targets for therapeutic management of patients with endometrial cancer, whose disease were progression and recurrence.
