They have identified the structure of a molecule called P-glycoprotein which, like a miniature machine, pumps chemotherapy drugs out of cancerous cells before they have a chance to kill them. Most types of cancerous tumor respond to chemotherapy, but they can later develop resistance to the toxic drugs which makes effective treatment difficult. Their knowledge of its structure will allow scientists to develop drugs to block its action, and this could help to solve the problem posed by drug-resistant tumors.
