| Research Abstract |
The pancreatic cancer is a devastating disease. We have performed the comprehensive metabolome analysis method based on capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS), which allows quantitative analysis of thousands of charged metabolites. This approach was applied to simultaneous analysis of metabolite levels in tumor and normal counterparts obtained from 24 patients with pancreatic cancer. Enhanced glycolysis was found in tumor tissues, indicating the Warburg effect, which is the enhanced conversion of glucose to lactate observed in tumor cells, even in the presence of normal levels of oxygen. In addition, quantification of hundred metabolites resulted in the identification of pancreatic cancer-specific metabolic traits. The amino acid concentrations were increased in tumor tissues. These data will apply into advanced imaging methods and blood tests to detect pancreatic cancer-specific metabolomes, which offer hope for such non-invasive early detection
