New insight into circadian rhythm increases our understanding of the ageing process

Disruptions in circadian rhythms may increase the risk for both cancer and premature ageing. Now researchers at the Department of Chemistry and Molecular Biology have demonstrated a mechanism through which light can affect a protein, peroxiredoxin, that has proved to be essential for biological clocks to function properly.
‘In our study, we have identified a new way for the cells to sense light, a signal chain that peroxiredoxin is part of’, says researcher Mikael Molin.
