Cortical-striatal gene expression in neonatal hippocampal lesion (NVHL)-amplified cocaine sensitization.


ABSTRACT: Cortical-striatal circuit dysfunction in mental illness may enhance addiction vulnerability. Neonatal ventral hippocampal lesions (NVHL) model this dual diagnosis causality by producing a schizophrenia syndrome with enhanced responsiveness to addictive drugs. Rat genome-wide microarrays containing >24?000 probesets were used to examine separate and co-occurring effects of NVHLs and cocaine sensitization (15?mg/kg/day?×?5?days) on gene expression within medial prefrontal cortex (MPFC), nucleus accumbens (NAC), and caudate-putamen (CAPU). Two weeks after NVHLs robustly amplified cocaine behavioral sensitization, brains were harvested for genes of interest defined as those altered at P?
