CARIBBEAN360 – A notorious cancer-causing protein has finally met its match thanks to a discovery unveiled by scientists at the University of Toronto.
The Ras protein is the most common cancer-causing protein, directly responsible for 30 percent of all cancers and indirectly involved in virtually all cancers.
It has evaded all attempts to target it for more than 30 years, but now the team of Canadian scientists has succeeded in turning it off with an experimental drug.
According to Michael Ohh, a professor in the Faculty of Medicine’s Department of Laboratory Medicine and Pathobiology: “For several decades, scientists have tried to turn off a protein called Ras, but despite their efforts, we ultimately haven’t seen much progress. In fact, it’s been coined the ‘undruggable’ protein.”
Ras normally promotes cell growth, but it can also cause uncontrolled cell growth when mutated or deregulated, according to MedicalXpress.
