Outline of Final Research Achievements |
We performed genomic analysis of schizophrenia, autism spectrum disorders (ASD) and bipolar disorder, identified variants strongly contributing to onset in RTN4R and CX3CR1 genes, and clarified their biological significance. RTN4R p.R292H mutation caused attenuation of interacting with its partner molecule LINGO-1 from in vitro functional analysis and revealed that it affected the formation of growth cones in elongating neurons (Kimuta et al., Translational Psychiatry, 2017). In addition, we also clarified that CX3CR1 p.A55T mutation caused structural instability by attenuating interaction with lipid molecules, and inhibited PI3K/Akt/mTOR signaling pathway (Ishizuka et al., Translational Psychiatry, 2017).
