Research Areas & Objectives

Research areas

TET2 and normal and pathological haematopoiesis


The overall aim of the group is to identify the acquired mutations in the early step of haematopoietic transformation, understand the network of cooperating events underlying transformation and develop experimental models to allow functional investigations and serve as preclinical models.

In particular, the team is investigating the role of TET2/3 and of 5mC/5hmC epigenetic marks in normal and malignant of both T-lymphoid and myeloid differentiation and is studying the cooperation between TET2 and DNMT3A mutations in transformation.
