None of what we do could be done without DNA science so the Gleevec™ targets a protein called BCR-ABL and this BCR-ABL protein belongs to a family of enzymes that regulate cell growth. It comes about because of 2 pieces of DNA exchanging segments. So it's a genetic disorder. It's something that people pick up, it's not inherited, it's something that people pick up in their bone marrows during their lifetime in one blood cell. Two pieces of DNA rearranged create this abnormal protein it's sort of like an accelerator of a car getting stuck on telling cells to grow continuously and they continue to grow and divide causing leukemia so it's directly related to DNA. What we've done, DNA as you know makes RNA makes protein and it's this protein that drives the growth of the leukemia cells. We shut down this protein, we shut down this leukemia and when these cells die the genetic abnormality in those cells goes away too.
Professor Charles Sawyer explains that CML stands for chronic myeloid leukemia, which is a blood cancer and it is different from many cancers because it starts very slowly and patients when they're first diagnosed don't have many symptoms.
