Programming probiotics for early detection of liver cancer metastases

Scientists at the University of California, San Diego and the Massachusetts Institute of Technology (MIT) have described a new method for detecting liver cancer metastases in mice. The approach uses over-the-counter probiotics genetically programmed to produce signals easily detectable in urine when liver cancer metastases are present. The results of the new study, published in the May 27 issue of Science Translational Medicine, indicate that genetically-programmed probiotics may be useful for d...
