St. Jude scientists discover new form and function of a key protein that may provide a novel cancer treatment target
Research led by St. Jude Children’s Research Hospital investigators suggests that safeguarding cell survival and maintaining a balanced immune system is just the start of the myeloid cell leukemia sequence 1 (MCL1) protein’s work. Nearly 20 years after MCL1 was discovered, scientists have identified a second form of the protein that works in a different location in cells and performs a different function. This newly identified version is shorter and toils inside rather than outside mitochondria where it assists in production of chemical energy that powers cells. The research appears in today’s online edition of the scientific journal Nature Cell Biology.
Among the research institutions NCI funds across the United States, it currently designates 66 as Cancer Centers. Largely based in research universities, these facilities are home to many of the NCI-supported scientists who conduct a wide range of intense, laboratory research into cancer’s origins and development. The Cancer Centers Program also focuses on trans-disciplinary research, including population science and clinical research. The centers’ research results are often at the forefront of studies in the cancer field.
