Tumor cell metabolism imaging.
Molecular imaging of tumor metabolism has gained considerable interest, since preclinical studies have indicated a close relationship between the activation of various oncogenes and alterations of cellular metabolism. Furthermore, several clinical trials have shown that metabolic imaging can significantly impact patient management by improving tumor staging, restaging, radiation treatment plann...
متن کاملCell Death Induction by Targeting Tumor Metabolism
Over the last century, a broader interest in the topic of tumor metabolism has emerged. From the 1920s onward, when Otto Warburg proposed increased aerobic glycolysis of tu‐ mor cells, a deeper understanding has established that tumor cells have an altered metab‐ olism which is directly linked to cancer progression. It was soon discovered that not only do environmental changes lead to alteratio...
متن کاملDNA Tumor Viruses and Cell Metabolism
Viruses play an important role in cancerogenesis. It is estimated that approximately 20% of all cancers are linked to infectious agents. The viral genes modulate the physiological machinery of infected cells that lead to cell transformation and development of cancer. One of the important adoptive responses by the cancer cells is their metabolic change to cope up with continuous requirement of c...
متن کاملTumor cell metabolism: cancer's Achilles' heel.
The essential hallmarks of cancer are intertwined with an altered cancer cell-intrinsic metabolism, either as a consequence or as a cause. As an example, the resistance of cancer mitochondria against apoptosis-associated permeabilization and the altered contribution of these organelles to metabolism are closely related. Similarly, the constitutive activation of signaling cascades that stimulate...
متن کاملChewing the Fat on Tumor Cell Metabolism
Tumor cells undergo a metabolic shift toward specific bioenergetic (glycolysis) and anabolic (protein and lipid synthesis) processes that promote rapid growth. Nomura et al. (2010) now demonstrate that an increase in monoacylglycerol lipase (MAGL) drives tumorigenesis through the lipolytic release and remodeling of free fatty acids.
