| Research Abstract |
The gene encoding WWOX is located in a chromosomal fragile site, and WWOX is a candidate for antitumor factor. The physiological function of WWOX has remained unknown. In the present study, we examined the role of WWOX in central nerve system using lde/lde rats in which a spontaneous mutation causes the loss of WWOX function. The expression of WWOX was detected in most of organs examined and in central nerve system such as cerebral cortex, hippocampus, and brainstem in normal rats. The neuronal and grail densities in cerebrum and brainstem were significantly lower in lde/lde than in normal rats. In the BrdU-incorporation assay, the number of BrdU-positive cells was significantly lower in the subventricular zone of lateral ventricle of lde/lde than that of normal rats. These results suggest that WWOX might be necessary for maintaining normal numbers of neuron and glia through the regulation of proliferation and differentiation in neuronal stem cells.
