A new study focuses on lactate – a molecule produced during intense exercise – and explains its role in cancer cell formation. New research, published in the journal Carcinogenesis, analyzes the role of lactate in oncogenesis. The new research – led by Inigo San Millan, director of the Sports Performance Department and physiology laboratory at the University of Colorado-Boulder’s Sports Medicine and Performance Center – set out to understand why cancer cells consume a lot more glucose than normal cells. Based on their findings, the researchers speculate that a sedentary lifestyle, combined with too much sugar in our diets, may lead to an excessive accumulation of lactate, thus setting the stage for cancer. San Millan hopes that, eventually, his research will help to develop drugs that stop the lactate from accumulating.
