Dr Asher said that a new approach to tackling obesity involves understanding the body’s circadian clock.
The circadian clock is the internal biological timing system that regulates the daily fluctuations in heartbeat, blood pressure, kidney function, secretion of hormones, body temperature, and sensory perception.
A single ‘master clock’ that resides in the brain was previously thought to control the body. However, Dr Asher said his research team have shown on a molecular and cellular level why this is not the case.
“We were surprised to find that every cell in your body has a circadian clock,” he says. The brain synchronises peripheral ‘clocks’ found in the cells of other organs.
Dr Asher said his team has discovered that a protein related to ageing and metabolism, called SIRT1, is the “missing link between the circadian clocks and metabolism”.
Dr Asher believes that he has identified the molecular mechanisms linking the circadian clock and metabolic disorders such as obesity and Type 2 diabetes in the laboratory.
