A new study by Georgetown University Medical Center researchers reveals how a well-known tumor suppressor gene may be functioning to stop cancer cell growth. The findings, published online today in Oncogene, focus on the gene BRCA1, which is mutated in a majority of families who have hereditary breast and/or ovarian cancers, according to senior author Ronit I. Yarden, PhD, assistant professor in the Department of Human Science at the School of Nursing & Health Studies.
"There is a debate in the scientific community about whether BRCA1 enzymatic activity is important in tumor suppressor function," Yarden said. "My lab thinks it is."
