Oncohistones as Drivers of Pediatric Brain Tumors (Nada Jabado)
Episode 81
August 11, 2022
In this episode of the Epigenetics Podcast, we caught up with Nada Jabado from McGill University to talk about her work on oncohistones as drivers of Pediatric Brain Tumors.
Nada Jabado and her team were amongst the first to identify mutations in Histone 3.3 Tails which lead to differentially remodelled chromatin in pediatric glioblastoma. Mutations that occur include the Lysine at position 27 and the Glycine at position 34. If those residues are mutated it will influence the equilibrium of chromatin associated proteins like the Polycomb Repressive Complex (PRC) and hence domains of heterochromatin will be shifted. This, in turn, will lead to differential gene expression and development of developmental disorders or cancer.
