St. Jude study finds protein prevents DNA damage in the developing brain and might serve as a tumor suppressor

St. Jude Children’s Research Hospital scientists have rewritten the job description of the protein TopBP1 after demonstrating that it guards early brain cells from DNA damage. Such damage might foreshadow later problems, including cancer. Researchers showed that cells in the developing brain require TopBP1 to prevent DNA strands from breaking as the molecule is copied prior to cell division.

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.
