The discoveries came as the result of general investigations into possible genetic causes of cancer. In this case, it was discovered that this particular gene, called BubR1, governs production of a protein that modulates physical aging. The mice studied lacked normal levels of that protein and began to age prematurely.

"Darren Baker in our laboratory found that mutant mice with low amounts of BubR1 protein live five times shorter than normal mice.
