GGT is important for glutathione homeostasis, and has also been used as a diagnostic marker for various pathologies in the liver, biliary system, and pancreas. Here, for the first time, a novel hyperpolarized 13C probe, γ-Glu-[1-13C]Gly, was demonstrated in vivo tumor xenografts, including human pancreatic ductal adenocarcinoma and ovarian adenocarcinoma, to detect real-time γ-glutamyl transferase activities as a prospective biomarker for monitoring the tumor progression and prognosis with/without various cancer therapeutic approaches.}, publisher = {ISMRM}, title = {Novel Real-time Hyperpolarized 13C Metabolic Tracer Probes γ-Glutamyl Transferase Activities in vivo Tumor Xenografts}, year = {2020} }
