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.

The present study documents the chromatin interaction profiles in the term pregnant not in labor human myometrial tissues at a genome-wide scale.
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:Profiles of PGR genome occupancy in human myometrial specimens were documented by ChIP-seq to investigate downstream targets of the progesterone receptor and candidate partner transcription regulators at the nonpregnant and term pregnant stages.
