The Redox Activity of Protein Disulphide Isomerase Functions in Non-Homologous End-Joining Repair to Prevent DNA Damage

3 weeks 2 days ago
DNA damage is a serious threat to cellular viability, and it is implicated as the major cause of normal ageing. Hence, targeting DNA damage therapeutically may counteract age-related cellular dysfunction and disease, such as neurodegenerative conditions and cancer. Identifying novel DNA repair mechanisms therefore reveals new therapeutic interventions for multiple human diseases. In neurons, non-homologous end-joining (NHEJ) is the only mechanism available to repair double-stranded DNA breaks...
