Research Interest

Any cell in an organism derives from the same starting genetic material. Functional distinction between cell types is acquired through sequential epigenetic modifications that shape chromatin and in turn affect transcription and cellular state. DNA methylation and Post-translational modifications (PTMs) of histones convey epigenetic information that extends the coding potential of nucleic acids, a phenomenon that has been commonly referred to as “histone code”. These PTMs are regulated and in turn influence the role of key transcription factors such as Myc. The interplay between these transcription factors, chromatin modifying enzymes and chromatin structure is of central importance in normal cell homeostasis and cancer. The long-term objective of the lab is a) to investigate the role of Arginine and Lysines Methyltransferases (PRMTs and HMTs), two families of transcriptional co-activators/repressors that target histones, in shaping of epigenetic landscapes and cellular identity and b) to assess the role of PRMTs and HMTs in epigenetic deregulation linked to cancer.
