In some aspects, the disclosure relates to compositions and methods useful for the diagnosis and treatment of diseases associated with a metabolic imbalance in a subject (e.g., cancer). In some embodiments, the methods comprise administering to a subject an N-acetylaspartate (NAA)-depleting agent or an N-acetylaspartate (NAA)-increasing agent based upon the subject's metabolic profile.
