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: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.

Project description:Infiltration of human myometrium and cervix with leukocytes and formation of a pro-inflammatory environment within the uterus has been associated with the initiation of both term and preterm parturition. The mechanism regulating the onset of this pro-inflammatory cascade is not fully elucidated. We demonstrate that prokineticin 1 (PROK1) is up-regulated in human myometrium and placenta during labour. Gene array analysis identified 65 genes up-regulated by PROK1 in human myometrium, mainly cytokines and chemokines including: Interleukin-1beta (IL1B), chemokine C-C motif ligand 3 (CCL3) and Colony Stimulating Factor 3 (CSF3). We additionally demonstrate that PROK1 increases expression of chemokines C-C motif ligand 20 (CCL20), Interleukin-6 (IL-6), Interleukin-8 (IL-8), prostaglandin synthase 2 (PTGS2) and prostaglandin E2 and F2? secretion. We propose that PROK1 is a novel inflammatory mediator that can contribute to onset of human parturition at term and partially mediate premature onset of inflammatory pathways during bacterial infection. Total RNA was extracted from human term non-labour myometrium explants treated with prokineticin for 6 and 24 hours compared to vehicle-treated explants. Six biological replicates were analyzed for each treatment and time point. Two of the 6-hour vehicle samples failed a quality-control analysis and were substituted with a 4-hour vehicle treatment from the same tissue sample in each case.

Project description:Gene differential expression in different pregnant periods and different tissues are detected. Sow ovary and myometrium were selected for RNA extraction and hybridization on Affymetrix microarrays. 9 pigs were divided into three time-points groups: non-pregnant (NP, n=3), early pregnant (EP, n=3), and late pregnant (LP, n=3). The differentially expressed genes in each group were identified.
