| Outline of Final Research Achievements |
Recent studies have implicated oligodendrocyte (OL) abnormalities in schizophrenia. To better elucidate the molecular mechanisms underlying the pathophysiology of schizophrenia, we investigated the function of DISC1-Binding Zinc finger protein (DBZ) in OL differentiation as DISC1 is a risk gene of schizophrenia. We examined the dynein cofactor, nuclear distribution E homolog 1 (NDE1), which binds to DBZ in OLs. Postnatally, when myelin formation is active, NDE1 mRNA is expressed in OL lineage cells in the mouse corpus callosum. An in vitro analysis revealed that NDE1 knockdown impaired OL differentiation. In addition, overexpression of the dynein-binding region of NDE1 resulted in impairments in OL differentiation like those observed following NDE1 knockdown. These results suggested that the DBZ-NDE1-dynein complex regulates OL differentiation.
