In this episode of the Epigenetics Podcast, we talked with James Hackett from the EMBL in Rome about his work on epigenetic mechanisms in genome regulation and developmental programming. One of James Hackett's significant studies focused on DNA methylation and genome defense mechanisms in the germline, exploring the role of chromatin modifications in mammalian gene regulation. He delves into investigating the erasure of DNA methylation in the germline, highlighting the key role of the TET-enzymes in demethylation processes. Moreover, James Hackett shares insights from his research on pluripotent stem cells, where he mapped genome-wide DNA methylation and hydroxymethylation in different pluripotent states. He discusses the impact of extrinsic conditions on pluripotent states and the biases observed in lineage preferences. Furthermore, the Interview then delves into the development of a CRISPR screening tool to study cell fate transitions, particularly focusing on the genetic factors contributing to germline specification. He also discusses his work on epigenetic inheritance, highlighting the importance of precise perturbations in understanding chromatin modifications and their functional implications. In a recent study, James focuses on systematic epigenome editing to investigate the context-dependent functions of chromatin modifications. He emphasizes the complexity of interactions between chromatin marks, DNA sequences, and transcription factors, shedding light on the nuanced effects of various chromatin modifications on gene expression.
