| Outline of Final Research Achievements |
Comprehensive analysis of metabolic pattern in lung cancer tissues and normal tissues using capillary electrophoresis-mass spectrometry (CE-MS) and imaging MS revealed that metabolites derived from glycolysis such as lactate, nucleic acid metabolites and branched chain amino acids were increased in the cancer tissues compared to the normal counterparts. Visualization of metabolites distribution by imaging MS revealed that 2 different kind of anti-angiogenic inhibitors, namely bevacizumab and nintedanib demonstrated distinct metabolic patterns despite both showed potent anti-tumor effect. We also identified anti-tumor effect of hyperoxia in lung cancer cell lines via activation of AMPK pathway, suggesting the possibility of clinical application of exposure to hyperoxia in lung cancer patients.
