Studied for decades for their essential role in making proteins within cells, several amino acids known as tRNA synthetases were recently found to have an unexpected -- and critical -- additional role in cancer metastasis. University of Vermont researchers determined that threonyl tRNA synthetase leads a "double life," regulating a pathway used by invasive cancers to induce the formation of new blood vessels, and a new food supply to sustain their growth.
