Research Unit

Hematopoiesis and Aging

Research interests

  • Characterization of the molecular causes of the development of clonal hematopoiesis associated with aging.
  • Precision medicine in myeloid cancers [myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN) and chromic myeloid leukemia (CML)]
  • Clinical research in myeloid cancer (MDS, NMP and CML)

  • Buscarlet M, Tessier A, Provost S, Mollica L, Busque L*. Human blood cell levels of 5-hydroxymethylcytosine (5hmC) decline with age, partly related to acquired mutations in TET2. Exp Hematol. 2016 November;44(11):1072-1084. PMID: 27475703
  • Buscarlet M, Provost S, Feroz Zada Y, Barhdadi A, Bourgoin V, Mollica L, Szuber N, Dubé MP, Busque L*. DNMT3A and TET2 dominate age-associated clonal hematopoiesis, have benign hematological phenotypes but different genetic predisposition. Blood (2017) 130 (6), 753-762.
