In this episode of the Epigenetics Podcast, we talked with Claire Rougeulle from the Epigenetics and Cell Fate Center at Université Paris City on this show to talk about her work on gene expression control, the intricacies of X-chromosome inactivation, and the potential of non-coding RNAs in this process.   Dr. Rougeulle explains her discoveries regarding the transcription regulation of XIST by factors like YY1 and the erosion of X-chromosome inactivation in human pluripotent stem cells. She shares the complexity of distinguishing between epigenetics and transcriptional regulation, highlighting the challenges in studying allelic expression of X-chromosomes at the single-cell level.  The Episode further explores Claire's findings on the XACT locus regulation, evolution from retroviruses, and its potential role in preventing X-chromosome silencing. Claire also shares her future research focus on understanding X-inactivation establishment in humans and the transition from XIST attenuating to silencing X-chromosomes after implantation.
