Study uncovers enzyme’s double life, critical role in cancer blood supply

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.
