BubR1 and its associated regulators promising targets for aging disorders and cancer

A new series of studies in mouse models by Mayo Clinic researchers uncovered that the aging process is characterized by high rates of whole-chromosome losses and gains in various organs, including heart, muscle, kidney and eye, and demonstrate that reducing these rates slows age-related tissue deterioration and promotes a healthier life span. The findings appear in today's online issue of Nature Cell Biology.
