A drug candidate that overstimulates proteins crucial for tumor growth shows promise as a new strategy to treat a wide range of cancers. The demands of rapid cell division put a strain on cancer cells, and the approach works by tipping cell stress over the edge. In the August 10 issue of Cancer Cell, American researchers show that the drug candidate inhibits tumor growth in a mouse model of breast cancer and efficiently kills a broad range of human cancer cells.
“No prior drug has been previously developed or proposed that actually stimulates an oncogene to promote therapy,” says co-senior study author David Lonard of Baylor College of Medicine. “Our prototype drug works in multiple types of cancers and encourages us that this could be a more general addition to the cancer drug arsenal.”
