Reduced NMDAR1 expression in the Sp4 hypomorphic mouse may contribute to endophenotypes of human psychiatric disorders.
The reduced expression of the Sp4 gene in Sp4 hypomorphic mice resulted in subtle vacuolization in the hippocampus as well as deficits in sensorimotor gating and contextual memory, putative endophenotypes for schizophrenia and other psychiatric disorders. In this study, we examined both spatial learning/memory and hippocampal long-term potentiation (LTP) of Sp4 hypomorphic mice. Impaired spatia...
متن کاملProlonged Ketamine Effects in Sp4 Hypomorphic Mice: Mimicking Phenotypes of Schizophrenia
It has been well established that schizophrenia patients display impaired NMDA receptor (NMDAR) functions as well as exacerbation of symptoms in response to NMDAR antagonists. Abnormal NMDAR signaling presumably contributes to cognitive deficits which substantially contribute to functional disability in schizophrenia. Establishing a mouse genetic model will help investigate molecular mechanisms...
متن کاملPresentation Title: Sp4 Hypomorphic Mice, a Hypoglutamatergic Genetic Model for Schizophrenia Location: Hall F-j
Print View Abstract: • Sp4 gene encodes a neuron-specific transcription factor that binds GC-rich DNA in the promoter of most genes. Its expression begins from E9.5 during mouse embryogenesis and persists throughout the adulthood. Sp4 knockout mice display reduced hippocampal size, subtle hippocampal vacuolization, as well as impaired postnatal development of hippocampal dentate gyrus. • Sp4 hy...
متن کاملGenetic bases for endophenotypes in psychiatric disorders
This article reviews the concept of an endophenotype, with particular reference to heritability as well as diagnostic specificity. An endophenotype need not be heritable, for example, the possible influence of in utero viral infections for schizophrenia. However, heritability is a useful characteristic for a potential endophenotype, as it can be studied in relation to a plausible candidate gene...
متن کاملRestoration of Sp4 in Forebrain GABAergic Neurons Rescues Hypersensitivity to Ketamine in Sp4 Hypomorphic Mice.
BACKGROUND Ketamine produces schizophrenia-like behavioral phenotypes in healthy people. Prolonged ketamine effects and exacerbation of symptoms after the administration of ketamine have been observed in patients with schizophrenia. More recently, ketamine has been used as a potent antidepressant to treat patients with major depression. The genes and neurons that regulate behavioral responses t...
