For decades, scientists have tried to halt cancer by blocking nutrients from reaching tumor cells, in essence starving tumor cells of the fuel needed to grow and proliferate. Such attempts often have disappointed because cancer cells are nimble, relying on numerous backup routes to continue growing. Now, scientists at Washington University School of Medicine in St. Louis have exploited a common weak point in cancer cell metabolism, forcing tumor cells to reveal the backup fuel supply routes they rely on when this weak point is compromised. Mapping these secondary routes, the researchers also identified drugs that block them. They now are planning a small clinical trial in cancer patients to evaluate this treatment strategy...
