Scientists at Yale Cancer Center in the US have uncovered the workings of a metabolic pathway or gauge that lets cancer cells detect when they have enough nutrients around them to grow. The researchers hope that drugs designed to turn down the gauge may eventually aid in treating many forms of cancer. The cancer cell has an unlimited appetite for nutrients said Xiaoyong Yang Associate Professor at Yale Cancer Center and senior author of the study. But in many parts of the body especially for solid tumours nutrients and oxygen are often limited so the cell has to make a
