Final Report Summary - GLIOMAGENESIS (Molecular and Cellular Mechanisms of Glioma Genesis)
In Aim 1, she proposed to clarify the role of Id4 in gliomagenesis and in adult neural stem cells, the potential cells of origin for GBMs. Her works suggests that Id4 acts as a factor that promotes quiescence of adult neural stem cells and that this function may be conserved in a tumoral setting.
In Aim 2, she proposed to characterize the successive stages leading from the transformation of cells of origin to tumor development, and the individual and combined contributions of defined genetic alterations. Although she initially planned to develop models for high-grade gliomas (such as GBMs), she focused on models of lower grade gliomas (such as oligodendrogliomas), as a result of the strong interactions that she developed with the neuro-oncology group at the institute, led by Pr. Marc Sanson. This collaboration led to the identification of novel mutations in oligodendrogliomas and to the characterization of the function of CIC/Capicua, a gene frequently mutated in these tumors, in oligodendrocyte precursor cells.
