Active Motif's Podcast

In this episode of the Epigenetics Podcast, we talked with Anders Sejr Hansen from MIT about his work on the impact of 3D genome structures on gene expression, the roles of proteins like CTCF and cohesin, and advanced techniques like Region Capture Micro-C for mapping genome organisation. Dr. Sejr Hansen introduces his research focusing on the relationship between three-dimensional genome structure and function, specifically how these structures can influence gene expression. He elaborates on the importance of transcription factors and the role of looping structures in gene regulation, emphasizing the implications of his work for understanding gene functionality in the context of both development and disease. The conversation then shifts to discussing loop extrusion and the factors affecting loop stability, primarily CTCF and cohesin. Dr. Sejr Hansen highlights the dynamics of these proteins' binding interactions and how their speeds challenge the notion of stable looping structures in the genome. With a keen
