The purpose of the study was to evaluate gene and environment interaction in a potential model of schizophrenia by employing a mouse line that maintains a 30% knockdown of the NMDAR1 subunit coupled with social isolation at weaning.
The hypothesis is that the genetic and environmental factors when influenced alone will produce subtle deficits, but when acting synergistically, it will likely elicit robust behavioral abnormalities as seen in human patients.
Our results show that a reduction in NMDAR1 and social isolation leads to working and long term memory impairments, social isolation, and hyperactivity. These features characterize the positive, negative and cognitive domains in schizophrenia. We also report changes in gene expression relating to neurogenesis, suggesting a dysregulation of the adult neuronal cell cycle.
We currently will investigate neuronal proliferation and survival using BrdU labeling, and perform microarray studies to elucidate key genes that are altered in this model.
