Hydroxymethylation Landscape in Immunecells (Marcela Sjöberg)

In this episode of the Epigenetics Podcast, we caught up with Marcela Sjöberg from the Pontificia Universidad Católica de Chile to talk about her work on the hydroxymethylation landscape in immune cells.

At the beginning of her career Marcela Sjöberg worked on Aurora B and Polycomb and how modifications placed by them modulate the binding of RNA Pol II. Later, her focus shifted to examine cytosine DNA methylation and hydroxymethylation changes in immune cells and how the epigenetic state of these marks varies between individuals and is reprogrammed for Metastable Epialleles in mouse. More recently, the laboratory is interested on how hydroxymethylation of transcription factor binding motifs influence binding and activity of the respective transcription factors in immune cells.
