Dietary tweak slows growth of deadly glioblastoma in mice, early study suggests
Northwell Health researchers found that a medically supervised diet modeled after treatment for GAMT deficiency—restricting arginine and boosting ornithine to curb the production of guanidinoacetate (GAA)—slowed glioma growth in mice, a result that could lead to pre-surgical testing in humans, with a clinical trial planned for 2027.
