Our body has an internal biological or "circadian" clock, which cycles daily and is synchronized with solar time. New research done in mice suggests that it can help suppress cancer. The study, publishing 7 December in the open access journal PLOS Biology by Dr Angela Relógio from the Charité-Medical University of Berlin, Germany and colleagues, hypothesised that given the range of molecular time-dependent processes that it regulates, including metabolism, DNA repair and the cell cycle, the circadian clock has the potential to act as a tumour suppressor.
