RNA processing-associated molecular mechanisms of neurodegenerative diseases.

Dysfunctions of RNA processing and mutations of RNA binding proteins (RBPs) play a fundamental role in the pathogenesis of many neurodegenerative diseases. To elucidate the function of RNA processing and RBPs mutations in neuronal cells and to increase our understanding on the pathogenic mechanisms of neurodegeneration, I have reviewed recent advances on RNA processing-associated molecular mechanisms of neurodegenerative diseases, including RBPs-mediated dysfunction of RNA processing, dysfunctional microRNA (miRNA)-based regulation of gene expression, and oxidative RNA modification. I have focused on neurodegeneration induced by RBPs mutations, by dysfunction of miRNA regulation, and by the oxidized RNAs within neurons, and discuss how these dysfunctions have pathologically contributed to neurodegenerative diseases. The advances overviewed above will be valuable to basic investigation and clinical application of target diagnostic tests and therapies.
