"When facial cartilage and bone is lost, from cancer or an accident, it has been difficult to replace. Our long term hope is that uncovering this gene circuit may be useful in reprogramming a patient's own stem cells to make facial cartilage."—Marianne Bronner, the Albert Billings Ruddock Professor of Biology at Caltech
Dr. Jacob Robbins, whose studies of the thyroid gland at the National Institutes of Health helped explain how it helps govern metabolism and how thyroid cancers caused by radiation may be treated or possibly prevented, died on May 12 in Bethesda, Md. He was 85.
With another endocrinologist at the health institutes, Joseph E. Rall, Dr. Robbins embarked on a study of thyroxine, an important hormone produced by the thyroid that helps regulate metabolism. In the 1950s, the two researchers theorized that levels of thyroxine might vary in the bloodstream, but that the level of thyroxine actually in use would often be markedly lower. They found that thyroxine had to be “free,” or not bound to globulin and other plasma proteins, to be effective, whatever the overall thyroxine level in the bloodstream.
