"(Medical Xpress)\u2014One of the hallmarks of cancer is unchecked cellular growth. Fortunately, our cells contain a number of tumor suppressor proteins, including the cell cycle regulator p21, to keep cell growth in check. The protection conferred by p21, however, can be overridden by an overactive histone-modifying enzyme called PRMT6. This protein represses p21 expression, thereby promoting tumor growth and preventing senescence in breast cancer cells, A*STAR scientists have found."^^<http://www.w3.org/2001/XMLSchema#string>
