Quotes

"But after some years, at the end of the war, in connection with my interest in application of chemistry to medicine, I learned about the disease sickle cell anemia. As soon as I learned about this disease, the very evening - it was at a dinner in New York where a medical research committee, of which I was a member, a committee which had been appointed by President Roosevelt to study medical research in the United States, was holding a meeting. At this dinner I learned about the disease sickle cell anemia and immediately I thought, 'Could it be possible that this disease, which seems to be a disease of the red cell because the red cells in the patients are twisted out of shape, could really be a disease of the hemoglobin molecule?' Nobody had ever suggested that there could be molecular diseases before, but this idea popped into my head. I thought, 'Could it be that these patients manufacture a certain kind of hemoglobin such that the molecules are sticky and clamp onto one another to form long rods which then line up side-by-side to form a long, needle-like crystal which, as it grows inside the red cell, becomes longer than the diameter of the cell and thus twists the red cell out of shape.' Well, I said to the man who was talking about the disease, Dr. Castle, 'Has anyone ever suggested that this might be a disease of the hemoglobin molecule?' And he said not so far as he had ever heard and I said, 'Do you think it would be alright if I were to look at the hemoglobin from these patients and see?' And he said 'I don't see why not.' So when I got back to Pasadena, it turned out that a young M.D., a young medical man wanted to come work with me in chemistry and get his Ph.D. degree. I said to him - his name is Harvey Itano - I said to him 'Why don't you work on the hemoglobin that you get from patients with the disease sickle cell anemia and see whether it is the same as hemoglobin in other humans or its different?' Nobody had ever found any difference between the hemoglobin of one person and another before that time. Well Dr. Itano did that, together with the two other young men in our laboratory - Dr. Singer and Dr. Wells. Pretty soon - it wasn't an easy job, these proteins are hard substances to work with - but after a while Dr. Itano and Dr. Singer and Dr. Wells were able to show that if they put a drop of hemoglobin solution from a patient with this disease in a little trough containing salt solution and applied an electric field - putting electrodes into this trough - the hemoglobin from the sickle cell anemia patients would move in one direction in this trough and that from ordinary individuals would move in the other direction. This was the proof that these patients have a different kind of hemoglobin; they manufacture a special kind of hemoglobin molecule which is the cause of their disease. This was the first molecular disease to be identified, that is the first disease to be shown due to the manufacture by the patient of an abnormal molecule."
