Research Focus
My research focuses on brain tumors, the leading cause of cancer-related mortality and morbidity in the pediatric years. Our main focus is pediatric and young adult astrocytomas, a deadly group of brain tumors. My group established that pediatric high-grade astrocytomas (HGA) are molecularly and genetically distinct from adult tumors. We identified a new molecular mechanism driving pediatric HGA, namely recurrent somatic driver mutations in the tail of histone 3 variants (H3.3 and H3.1). These mutations lead to aminoacid substitutions at key residues and are tightly correlated with a distinct global DNA methylation pattern, neuroanatomical and age specificities. We aim to identify events affected downstream of each mutation, and validate targets in our new models to better advise the use of experimental or pipeline drug(s) that could be rapidly translated into clinical trials.
