Scientists discover a protein that silences the biological clock A protein associated with cancer cells is a powerful suppressor of the biological clock that drives the daily ('circadian') rhythms of cells throughout the body. The discovery adds to a growing body of evidence suggesting a link between cancer and disruption of circadian rhythms, while offering new insights into the molecular mechanisms of the biological clock.
