Dr Patrick Pollard tells us about his research on cancer metabolism. Cancer cells produce energy predominately through a high rate of glycolysis; it has been suggested that this change in metabolism is the fundamental cause of cancer. Dr Patrick Pollard aims to elucidate the alternative metabolic strategies used by cancer cells with high concentrations of glucose to proliferate, even under conditions of stress. These mechanisms could then become targets for more effective cancer therapies.
