• Scientists at the University of Sheffield discovered that the drug methotrexate used for arthritis could be used to treat blood cancer patients. Initial tests were conducted on fruit fly cells. Further testing in human cells demonstrated the potential of methotrexate to directly inhibit the molecular pathway responsible for blood cancer.  Read more about these findings in Haematologica.
• The use of a contrast agent that makes tumors glow enabled surgeons to identify and remove a greater number of cancerous nodules. Researchers at the University of Pennsylvania used a near-infrared contrast agent called OTL3 when combining intraoperative molecular imaging with PET imaging.  For more, see study published in the Annals of Surgery.
