Epigenetics Podcast

In this episode of the Epigenetics Podcast, we caught up with Peter Sarkies from University of Oxford Biochemistry to talk about his work on Transgenerational Inheritance of Epimutations.

The team in the Sarkies lab focuses on investigating the connections between epigenetic gene regulation and evolution. The lab performs evolution experiments in the nematode C. elegans to determine if evolution can be influenced by epigenetic differences between individuals in a given population when no changes in the underlying DNA sequence are observed. A second area of interest of the team is evolution of piRNAs, which are present in metazoans but have been lost in nematodes during evolution.
