代谢成像在癌症中具有巨大的临床潜力,因为代谢紊乱是恶性细胞转化的常见标志。针对谷氨酰胺的新成像策略可以为18氟葡萄糖正电子发射断层扫描(18FDG-PET)提供有价值的补充,因为谷氨酰胺在细胞水平上补充葡萄糖的代谢平台,支持肿瘤的生长。此外,最近的研究表明谷氨酰胺代谢的不同方面受到癌基因和肿瘤抑制因子的控制。似乎谷氨酰胺代谢成像可以预测肿瘤中特定转化突变的存在以及对靶向谷氨酰胺利用的治疗剂的敏感性。在这里,我们回顾了谷氨酰胺在癌细胞代谢的基本方面,并讨论了癌症患者成像的机会。
Metabolic imaging has great clinical potential in cancer because perturbations of metabolism are common hallmarks of malignant cellular transformation. Novel imaging strategies focused on glutamine could provide a valuable complement to 18fluoro-dexoyglucose positron emission tomography (18FDG-PET), because glutamine complements glucose in the metabolic platforms that support tumor growth at the cellular level. Furthermore, recent work has demonstrated that distinct aspects of glutamine metabolism are under the control of oncogenes and tumor suppressors. It is plausible that imaging glutamine metabolism could predict both the presence of specific transforming mutations in the tumor and the sensitivity to therapeutic agents designed to target glutamine utilization. Here we review the essential aspects of glutamine metabolism in cancer cells and discuss opportunities for imaging in cancer patients.
