Epigenetics Podcast

In this episode of the Epigenetics Podcast, we talked with Christa Bruecker from the Max Perutz Laboratories in Vienna about her work on transcriptional regulation during early embryonic development.  Christa Buecker unravels the differences between naive and primed pluripotency states, showcasing how OCT4 relocalization and enhancer chromatin landscapes play pivotal roles during this transition. The conversation delves into the intricate interplay of transcription factors like OCT4 and OTX2, shedding light on their collaborative efforts in regulating gene expression during differentiation.  Dr. Bücker then shares insights from her study on enhancer elements controlling FGF5 expression and discusses the surprising revelation that individual enhancers show no intrinsic activity but work together in a super additive fashion. She also touches upon her research on IRF1's connection to the gene regulatory network and its role in protecting cells against viral infections.  The conversation shifts to Dr. Bücker's current research endeavors, focusing on exploring the strength of enhancers and their impact on gene expression at different distances from promoters. She shares her vision for future experiments and the integration of enhancers to decipher their impact on transcription regulation.
