Project description:PPARG ChIP seq analysis was conducted to determine genes bound by and potentially regulated by PPARG in the developing ovine conceptus. Determination of gene regulation by prostaglandins through PPARG helps to improve our understanding of early pregnancy events and provides a basis for strategies to improve fertility and reproductive efficiency in ruminants.

Project description:RNA seq analysis was conducted to determine gene expression in the day 14 ovine conceptus. This was used in conjunction with the day 14 PPARG ChIP-seq analysis to identify genes bound by PPARG which were also expressed or not expressed in the day 14 conceptus. Understanding changes in gene expression during early pregnancy is critical to improving fertility and reproductive efficiency in ruminants.

Project description:The present studies tested the hypothesis that the elongating ovine conceptus and uterus produces EVs with the potential to mediate conceptus-maternal communication during early pregnancy. In Study One, EVs were purified from uterine luminal fluid (ULF) of day 14 cyclic sheep. The EVs were fluorescently labeled with PKH67 dye and infused into the uterine lumen of pregnant sheep for 6 days using an osmotic pump. On day 14, labeled EVs were observed in the conceptus trophectoderm and uterine epithelia, but not in the uterine stroma or myometrium. In Study Two, day 14 conceptuses were cultured ex vivo for 24 hours and found to release EVs into the culture medium. Isolated EVs from conceptuses were fluorescently labeled with PKH67 and infused into the uterine lumen of cyclic sheep for 6 days using an osmotic pump. On day 14, labeled EVs were observed in the uterine epithelia, but not in the uterine stroma or myometrium. No evidence of EV escape from the uterine lumen was observed by analysis of the ovary and other maternal tissues. Proteomics analysis of the day 14 conceptus-derived EVs identified 231 proteins that were enriched for extracellular space and several protein classes including proteases, protease inhibitors, chaperones and chaperonins. RNA-sequencing of day 14 conceptus-derived EVs detected expression of 512 mRNAs. The top expressed genes were overrepresented in ribosomal functions and components. These studies support the ideas that EVs emanate from both the conceptus trophectoderm and uterine epithelia and are involved in intercellular communication during the establishment of pregnancy. Transcriptional profiles from day 14 conceptus extracellular vesicles isolated from 24 hour conceptus-conditioned culture media (n=3) were generated by sequencing on the Illumina HiSeq 2500 platform.
