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:Recently, microRNAs (miRNAs), known to modulate gene expression through post-transcriptional mechanisms, were implied in regulation of early pregnancy events including maternal recognition of pregnancy and implantation. To characterize complex transcriptomic changes in expression of miRNAs in pregnant and cyclic endometria collected on days 12, 16 and 20 was analyzed using Illumina deep sequencing. This research showed repertoire of pregnancy-related miRNAs in porcine endometrium during initial stages of conceptus implantation and during the estrous cycle and sheds light on miRNA-mediated gene expression regulation mechanism at the maternal-conceptus interface.

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.
