Cell plasticity may provide clues to origin of aggressive type of breast cancer

A team of researchers, led by Candice A.M. Sauder, M.D., while a resident at the Indiana University Department of Surgery, reported online in BMC Cell Biology that healthy breast cells separated from their normal environment were able to transform into types of cells similar to those seen in metaplastic carcinoma, a form of triple negative breast cancer. …

Retinoblastoma dysfunction promotes pancreatic cancer cell growth, study shows

Murray Korc, M.D., the Myles Brand Professor of Cancer Research at the Indiana University School of Medicine and a researcher at the Indiana University Melvin and Bren Simon Cancer Center, and colleagues have shown that the retinoblastoma protein, a tumor suppressor, often malfunctions in pancreatic cancer. That dysfunction enables an inhibitory protein to promote pancreatic cancer growth. The research was published online today in the Journal of Clinical Investigation. As a result of the dysfunctional retinoblastoma protein, pancreatic cancer cells lose their ability to be inhibited by transforming growth factor-beta, or TGF-β, which is a key negative regulator of cell proliferation, according to Dr…
