| Outline of Final Research Achievements |
One of the major female sex hormones, estrogen, can influence a variety of mental states. Individuals with multiple sclerosis (MS) often suffer from mental health issues, which are correlated with the pathology of gray matter. In this study, we aimed to elucidate the validity of phytoestrogen genistein (GEN) for the cuprizone (CPZ)-induced demyelination. Five weeks CPZ intoxication induced demyelination in the hippocampus, and that myelination was successfully recovered by GEN. Loss of mature oligodendrocytes following CPZ intoxication was counteracted by GEN. The expression levels of myelin-related genes in the whole hippocampal tissue were decreased by CPZ but recovered by GEN. These results show that GEN may act on mature oligodendrocytes in the hippocampus by promoting their survival and myelin formation, and suggest the therapeutic potential of phytoestrogens for treating MS patients suffering from mental health issues.
