GENOMIC INSTABILITY – A Root Cause of Aging

WebA strong causal link between genome instability and aging has been established in the model system S. cerevisiae. In this system, cell division is asymmetric, giving rise to a large mother cell and a smaller daughter cell. Aging is manifest both by the limited number of cell divisions and the changes in phenotype undergone by mother cells prior ... WebJul 21, 2024 · Efficient DNA repair is critical to the maintenance of genome integrity. Defects in different types of DNA repair pathways such as c-NHEJ or BER often lead to phenotypes of premature aging (Li et al., 2024; Lombard et al., 2005).
