2022 Sontag Award Recipient

"It is an honor to be a recipient of the Sontag Distinguished Scientist Award. The Sontag Foundation will provide a network and mentorship that fosters working collaboratively with a group of people to achieve a common goal. I’m truly excited to be a part of this amazing team to make meaningful discoveries that have a translational impact on brain tumors."

About DSA-Funded Research

Brain tumors are the leading cause of cancer-related deaths in children. Moreover, patients with aggressive brain tumors such as DMG/DIPG have a 5-year survival rate of only 2%. While the cellular machinery for signaling, growth and epigenetic modifications is characterized, the enzymes required to produce the metabolic co-factors essential for these epigenetic modifications (Histone, RNA and DNA) are poorly understood. To address this knowledge gap, we hypothesize that DIPG cells use one-carbon metabolism to promote growth, by altering the epigenome (DNA) and the epitranscriptome (RNA) by production of novel oncometabolites. Using innovative models, and emerging metabolomic techniques, we will interrogate the role of methionine metabolism on glioma growth. If our hypothesis is correct, we envision targeting metabolism (by dietary intervention or small molecule inhibitors) becoming a mainstay therapy in brain tumors.
