A research team studied the reactive oxygen species, which includes hydrogen peroxide and hydroxyl radicals used commonly in chemotherapy. Common cancer therapies, including chemotherapy, are based on the action of ROS generated by the drug on cancer cells. To optimise ROS-generating cancer treatment and counter-treatments, oxidative stress is often assessed through measurement of the antioxidant levels in the cells. We are collaborating with cancer hospitals to try our ‘simple timing’ strategy to enhance the effectiveness of cancer treatment,” Mr. Suraishkumar said. “Our observations make us wonder if using antioxidant levels to decide the therapy parameters is less useful than generally believed,” the professor added.
