And actually by studying this specific type of mechanism, we were able to create different types of drugs which act as anticancer, anti tumor agents. And these drugs are essentially antibodies. So we were able to develop these antibodies in a laboratory that actually bind onto these EGF receptors. And once the antibody binds onto these pockets of the EGF receptor, that can basically inactivate these receptors. And by inactivating these receptors, that decreases the likelihood that this will lead to producing a cancer cell. And so one important drug that is basically used to treat individuals who have breast cancer is known as herceptin.
