A research team from the School of Biomedical Sciences at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has achieved a significant advance in biotechnology that could revolutionize treatment strategies for neurodegenerative diseases. The team has developed a novel tool called RNA Segment Editing (RSE), which functions like a "cut-and-patch" tool for RNA. This innovative approach allows scientists to precisely remove or replace faulty segments of genetic messages within living cells without permanently changing a person's DNA.
