A novel approach to suppress the growth of glioblastoma cells Inhibiting a key enzyme that controls a large network of proteins important in cell division and growth paves the way for a new class of drugs that could stop glioblastoma, a deadly brain cancer, from growing. Researchers at Princess Margaret Cancer Centre, the Hospital for Sick Children (SickKids) and University of Toronto, showed that chemically inhibiting the enzyme PRMT5 can suppress the growth of glioblastoma cells. The inhibition of PRMT5 led to cell senescence, similar to what happens to cells during aging when cells lose the ability to divide and grow. Cellular senescence can also be a powerful tumor suppression mechanism, stopping the unrelenting division of cancer cells.
