Project description:We have generated genome-wide binding and expression datasets in uterine smooth muscle (myometrium) from murine models of pregnancy and labour. ChIP-seq and total RNA-seq experiments were conducted to evaluate changes in the genomic and transcriptomic landscape of the myometrium prior to, during, and after labour onset.

Project description:The myometrium undergoes structural and functional remodeling during pregnancy. We hypothesize that myometrial genomic elements alter correspondingly in preparation for parturition. Human myometrial tissues from nonpregnant (NP) and term pregnant (TP) human subjects were subject to RNAseq, ATAC-seq and PGR ChIP-seq assays to profile transcriptome, assessible genome and PGR occupancy.

Project description:Timely control of parturition is crucial for maternal and fetal health. Failures on this biological process often result in pregnancy complications including preterm birth, labor dystocia, and health disorders on newborn babies. The myometrium is the muscular structure of the uterus maintaining uterine structural integrity and providing contractile force for parturition. The myometrial structure changes in adaptation to the pregnancy via stage-specific transcriptomic profiles. Data from the mouse model indicate that changes of myometrial epigenomic landscape precedes the adoption of stage-specific gene expression pattern at term. The present study documents the transcriptomic profile and epigenomic landscape of term pregnant myometrial tissues and functionally characterize a subset of putative enhancers to further understand the enhancer-gene interaction in human the myometrium.

Project description:Preeclampsia (PE) is characterized by sustained hypertension and proteinuria at a gestational age of 20 weeks or more. Immune system alterations are associated with the origin and the pathophysiology of preeclampsia, however, little is known about the landscape and heterogeneity of maternal immune system at the single-cell level. In this study, we performed single-cell RNA sequencing of 80,429 cells in PE patients and health controls, including T cells, B cells, natural killer (NK) cells, myeloid cells in peripheral blood mononuclear cells to characterize the immune cell subgroups at the pregnant and postpartum stages of PE. Our work showed that there was excessive activation of B cells, monocytes and NK cells in PE patients at the pregnant stage. Additionally, lower immune response activation was noticed in CD4+ and CD8+ T cells in PEs, especially the low-activation of memory T cells at the pregnant and postpartum stages. Moreover, there was a higher activation of B cells in pregnancy persisted postpartum in PEs, together with lower activation of memory T cells. These indicated their persistent effects on PE and its recurrence risks.

Project description:The alterations in myometrial biology during labor are not well understood. The myometrium is the contractile portion of the uterus and contributes to labor, a process that may be regulated by the steroid hormone progesterone. Thus, human myometrial tissues from term pregnant in-active-labor (TIL) and term pregnant not-in-labor (TNIL) subjects were used for genome-wide analyses to elucidate potential future preventive or therapeutic targets involved in the regulation of labor. Using myometrial tissues directly subjected to RNA sequencing (RNA-seq), progesterone receptor (PGR) chromatin immunoprecipitation sequencing (ChIP-seq), and histone modification ChIP-seq, we profiled genome-wide changes associated with gene expression in myometrial smooth muscle tissue in vivo. In TIL myometrium, PGR occupied predominatly promoter regions including the classical progesterone response element, whereas it bound predominantly to intergenic regions in TNIL myometrial tissue. Differential binding analysis uncovered over 1700 differential PGR-bound sites between TIL and TNIL with 1361 sites gained and 428 lost in labor. Functional analysis identified multiple pathways involved in cAMP-mediated signaling enriched in labor. A three-way integration of the data for ChIP-seq, RNA-seq and active histone marks uncovered the following genes associated with PGR binding, transcriptional activation and altered mRNA levels: ATP11A, CBX7, and TNS1. In vitro studies showed that ATP11A, CBX7, and TNS1 are progesterone responsive. We speculate that these genes may contribute to the contractile phenotype of the myometrium during various stages of labor. In conclusion, we provide novel labor associated genome-wide events and PGR-target genes that can serve as targets for future mechanistic studies.
