In this episode of the Epigenetics Podcast, we caught up with Marcela Sjöberg from the University of Chile to talk about her work on the hydroxymethylation landscape in immune cells.
At the beginning of her career Marcela Sjöberg worked on Polycomb and how modifications placed by this complex modulate the binding of RNA Pol II. Later, her focus shifted to hydroxymethylated cytosine and how it is involved in the inheritance of Metastable Epialleles in mouse. More recently, the laboratory is interested in transcription factor binding motifs and how hydroxymethylation of those binding motifs modulates the binding and activity of the respective transcription factors.
