Genome-wide binding sites of Progesterone receptor (PGR) isoforms PGR-A and PGR-B during differentiation of human endometrial stromal cells

Project description:We report the genome-wide binding sites of PGR-A and PGR-B at 2h of in vitro differentiation of human endometrial stromal cells that express either PGR-A or PGR-B. Progesterone, acting through the progesterone receptors (PGRs), is one of the most critical regulators of endometrial differentiation, known as decidualization, which is a key step toward the establishment of pregnancy. Yet a long-standing unresolved issue in uterine biology is the precise roles played by the major PGR isoforms, PGR-A and PGR-B, during decidualization in the human. Our approach, expressing PGR-A and PGR-B individually after silencing endogenous PGRs in human endometrial stromal cells (HESC), enabled the analysis of the roles of these isoforms separately as well as jointly by ChIP-seq and gene-expression analysis. In order to study the cistromes of PGR-A and PGR-B at 2h of in vitro differentiation of human endometrial stromal cells, we generated primary cultures of human endometrial stromal cells expressing flag tagged PGR-A and PGR-B individually after silencing endogenous PGRs. Input DNA was used as the reference sample.

TRIM28 modulates progesterone and estrogen signaling in endometrium [mouseD35-PGR-ChIPseq-mm10]

Project description:TRIM28 interacts with PGR and ESR1 in both human and mouse uterus to modulate estrogen and progesterone signaling. Knocking down of TRIM28 in the human endometrial stromal cells impaired decidualization in vitro. Deletion of TRIM28 from mouse uterus disrupted uterine stromal decidualization leading to infertility. Additionally, TRIM28 deletion caused abnormal accumulation of TRIM28 positive and PGR negative cells in the stroma.

The role of epithelial Progesterone Receptor Isoforms in embryo implantation [ChIPseq-PGR-H3K27AC]

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.

PGR Isoform Modulation via Enhancer Activation Regulates Progesterone Signaling in Human Endometrial Stromal Cells [CUT&RUN]

Project description:Progesterone, acting through its isoform receptors PGR-A and PGR-B, is essential for regulating uterus function. The ratio between these isoforms is dynamic and context-dependent, driving distinct transcriptional programs. The upstream mechanisms controlling the PGR isoform balance and their functional impact in the uterus remain poorly understood. In this study, we identified two distal PGR enhancers in endometrial stromal cells located 60 kb and 220 kb upstream of the PGR transcription start site. We found that in comparison to PGR promoter-targeting which favors a PGR-B dominant profile, activation of these enhancers shifts the isoform ratio by increasing PGR-A and decreasing PGR-B expression. Bulk RNA-sequencing revealed that the isoform balance alters the progesterone-regulated transcriptome. PGR-A/B-equivalent cells displayed pro-inflammatory gene signatures, whereas PGR-B-dominant cells exhibited suppression of inflammatory signaling and cell cycle activity. Cut&Run assays identified differential genomic binding patterns associated with each isoform profile, and integration with chromatin interaction maps suggest direct regulation of distinct gene subsets. Upstream, ESR1 indirectly activated the PGR-A isoform dominantly, potentially through cooperation with FOXO1 at the U2 enhancer. This study identifies a novel enhancer-driven mechanism regulating PGR isoform dynamics and sheds light on how their imbalance in the endometrial stroma may reshape progesterone signaling in health and disease.

Gene expression analysis of granulosa cells from animals that are wildtype or knockout for total PGR, PGR-A or PGR-B (RNA-seq)

Project description:Progesterone receptor (PGR) is essential for various functions in the female reproductive tract, especially ovulation in the ovary. PGR consists of two main isoforms, PGR-A and PGR-B, that possess different expression patterns and are responsible for various unique roles in different tissue contexts. While both are present in the reproductive tract, PGR-A is the only one known to be essential for ovulation while PGR-B plays a lesser role in the reproductive tract. However, the specific roles of PGR isoforms on gene expression in peri-ovulatory granulosa cells have not been previously investigated in detail. In this study, we identified the unique role of PGR-A and PGR-B in peri-ovulatory granulosa cells through RNA-seq of knockout mouse models for total PGR (PGR KO) or specific isoforms (PGR-A KO and PGR-B KO)
