Researchers unravel important role of Rb tumor suppressor in aggressive form of breast cancer

The retinoblastoma (Rb) protein plays a critical role in suppressing the multi-step process of cell migration through the bloodstream, lymphovascular invasion and the metastasis of an aggressive type of breast cancer to the lung, researchers at the University of Cincinnati (UC) Cancer Institute, the Cincinnati Cancer Center (CCC) and the UC Brain Tumor Center have found. The findings of Rb’s role at multiple points in the disease process point to a potential new therapeutic target in patients with the most aggressive subset of breast cancer, known as basal-like breast carcinomas. This type of cancer has no estrogen receptor expression, and…
