Active Motif's Podcast

In this episode of the Epigenetics Podcast, we talked with Carl Wu from John's Hopkins University about his work on nucleosome remodeling, histone variants, and the role of single-molecule imaging in gene regulation. Our discussion starts with Carl Wu sharing his first significant milestones, a paper in "Cell" and the serendipitous discovery of DNA hypersensitive sites, which transformed our understanding of chromatin accessibility and its implications for gene regulation. As we delve into Dr. Wu’s specific areas of research, he elaborates on the biochemistry of nucleosome remodeling and the intricate role of chromatin remodeling enzymes like NURF. We discuss how these enzymes employ ATP hydrolysis to reposition nucleosomes, making DNA accessible for transcription. He then explains the collaborative relationship between chromatin remodelers and transcription factors, showcasing the fascinating interplay that governs gene expression and regulatory mechanisms. The conversation takes a deeper turn as we explore
