Novel 'On-Off Switch' Mechanism Stops Cancer in Its Tracks

In the papers, Alan Garen of the Department of Molecular Biophysics & Biochemistry at Yale and his colleague Xu Song explain how cancer may overcome an organism’s natural “stop sign” for cell division.
During early development, stem cells give rise to other cells that differentiate into all types of tissue. New cell division and proliferation stop as the organism matures. However, cancer can hijack this process and trigger the uncontrolled cell division that produces cancer tumors.
One mechanism that stops cell proliferation is a family of tumor-suppressor proteins (TSP) that bind to and block the function of proto-oncogenes, or genes that have the potential to trigger cancer.
