  1. Resource Description
    Nr4a family gene expression increases within the hippocampus after training in a hippocampus-dependent task. The dominant-negative form of NR4A1 (NR4ADN) contains the DNA-binding and dimerization domains but lacks the transactivation domain. It silences the three Nr4a family members. We generated a transgenic mouse line expressing the NR4ADN construct under control of the tetracycline operator (tetO), which we combined with the CaMKII–tetracycline transactivator (CaMKII-tTA) transgene to achieve expression selectively within postnatal excitatory forebrain neurons. The dominant-negative protein interacts with NR4A proteins in vivo. Transgene expression was restricted in the forebrain to the striatum, sparse cortical areas, and subregions of the hippocampal formation (CA1 and the dentate gyrus). Transgene expression was not observed in the amygdala or in area CA3 of the hippocampus. Nr4a polymorphisms have been identified in patients with schizophrenia, and Nr4a gene expression is reduced in patients with schizophrenia. Thus, impaired Nr4a function may contribute to the cognitive impairments that accompany this psychiatric disorder.
