First confirmed common genetic risk factors for breast cancer
...that these five genes code for proteins crucial to biological
activities that previously had not been implicated as triggers of breast cancer. The genes carry the DNA recipes for proteins important to the growth and duplication of body cells and the signalling, or communications, that must occur between cells ...

phenomenon during T cell development is the focus of studies performed by Dr. Guyden at The City College of New York and his colleagues at Tuskegee University. Thymic nurse cells were discovered in 1980. Their existence was heavily debated because...
Tiny genes may increase cancer susceptibility, Jefferson scientists find
...te in Buffalo. MiRNAs play a number of roles in biological
regulation, including development and cell differentiation, helping to determine what type a cell ultimately becomes. But when damaged, they can contribute to cancer by either turning on cancer-causing genes or by inhibiting tumor-blocking genes. The...
