Investigators at the University of Toronto say that the S100A7 protein can be used to flag precancerous oral lesions, precursors to cancer of the mouth, which is a particularly serious threat in Asia. "We are extremely pleased to have identified a protein which can predict which oral dysplastic lesions will transform. This will be a great tool to find out which patients really need closer follow-up, and in time this will lead to better patient survival," says Paul Walfish, director of the Mount Sinai Hospital's Alex and Simona Shnaider Research Laboratory in Molecular Oncology.
