  • Summary

  • In this episode of the Epigenetics Podcast, we talked with Sarah Marzi from the UK Dementia Research Institute at Imperial College London about her work on epigenetic changes in Alzheimer's Disease, and comparing CUT&Tag to ENCODE ChIP-Seq using limited cell samples. The interview discusses Sarah Marzi's work on ChIP-Seq experiments and their significance in understanding Alzheimer's disease from an epigenetic perspective. The discussion touches on the widespread dysregulation and changes in acetylation, particularly in genes associated with Alzheimer's risk, providing insights into potential links between epigenetic insults and disease onset. Moving on to the technical aspects of the study, the interview examines the strategic use of CUT&Tag. It explores the challenges and optimizations involved in accurately profiling limited cell samples. The dialogue also compares CUT&Tag to ENCODE ChIP-Seq, highlighting the complexities of peak calling and data interpretation across different methodologies.
