| Outline of Final Research Achievements |
Cancer cells exhibit altered glucose metabolism, termed the Warburg effect, which is described by the increased uptake of glucose and the conversion of glucose to lactate in cancer cells under adequate oxygen tension. Overexpression of transcriptional factors, metabolite transporters and glycolytic enzymes was associated with poor prognosis and may be associated with chemoradiotherapy resistance in multiple gastrointestinal cancer cell types. In esophageal squamous cell carcinoma, the expression of glucose transporter 1 (Glut1) increased. Glut1 positivity of biopsy before chemotherapy was associated with the reduction rate of FDG-PET SUV max after chemotherapy. Glut1 may be significant biomarkers for predicting the resistance of chemotherapy.
