When is a Peak a Peak? (Claudio Cantu)

Published: July 27, 2023, 7:01 a.m.

In this episode of the Epigenetics Podcast, we talked to Claudio Cant\xf9 from Link\xf6ping University about his work on peak blacklists, peak concordance and what is a peak in CUT&RUN.\nOur host Stefan Dillinger and guest Claudio Cant\xf9 dive into the topic of when we can be sure that a peak is a peak. To help with this, Claudio Cant\xf9's group has been working on defining a set of suspicious peaks that can be used as a "peak blacklist" and can be subtracted to clean up CUT&RUN data sets. The lab also worked on a method called ICEBERG (Increased Capture of Enrichment By Exhaustive Replicate aGgregation) to help define peaks from a number of experimental replicates. By using this algorithm, the team is trying to discover the beta-catenin binding profile, not the tip of the beta-catenin binding iceberg, but the whole of the beta-catenin binding profile.\n\xa0\nReferences\n\nZambanini, G., Nordin, A., Jonasson, M., Pagella, P., & Cant\xf9, C.
