For instance, we have cancers like breast cancers, ovarian cancers, colorectal cancers and so forth. So any place we have these epithelial cells, this can actually cause this type of cancer. So, if a cell expresses too many receptors, that access receptors may stimulate growth at inappropriate times. 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.
