Topic: Negr1-deficient mice

The NEGR1 (neuronal growth regulator 1) gene has been associated with schizophrenia phenotype in GWAS studies and its expression has been found to be altered in the brains of patients with schizophrenia spectrum disorders. As altered profile of circulating kynurenine pathway metabolites has been linked with schizophrenia spectrum disorders as well, we aimed to find the differences in the brain and blood serum metabolite levels between wild-type mice and Negr1-deficient mice using MK-801 (dizocilpine) and a high-fat diet. The results suggest that kynurenine metabolism is strongly biased towards
