New study reveals a link between circadian clock disruption and tumor growth

A handful of large studies of cancer risk factors have found that working the night shift, as nearly 15 percent of Americans do, boosts the chances of developing cancer. MIT biologists have now found a link that may explain this heightened risk.

In a study of mice, the MIT team found that two of the genes that control cells' circadian rhythms also function as tumor suppressors. Loss of these tumor suppressors, either through gene deletion or disruption of the normal light/dark cycle, allows tumors to become more aggressive.
