A targeted approach: Gene and RNA editing for neurodegenerative disease treatment

Abstract

With the global aging trend, neurodegenerative diseases (NDs) have emerged as a significant public health concern in the 21st century, imposing substantial economic burdens on families and society. NDs are characterized by cognitive and motor decline, resulting from a combination of genetic and environmental factors. Currently, there is no cure for NDs. Gene and RNA editing therapies offer new possibilities for addressing NDs. Gene editing involves modifying mutant genes associated with NDs, while RNA editing can directly modify RNA molecules to regulate the protein translation process, potentially influencing the expression of genes related to NDs. In this review, we examined the historical evolution, mechanisms of action, applications in NDs, advantages and disadvantages, as well as ethical and safety considerations of gene and RNA editing. While gene and RNA editing technologies hold promise for treating NDs, further research and development are needed to address safety, efficacy, and treatment timing issues, ultimately offering improved treatment options for ND patients. Our review provides valuable insights for future gene and RNA editing applications in ND treatment.
