Significant correlation of proliferating cancer cells was observed with GLUT-1, TKTL1 mitochondrial markers SDHA, SDHB, and ATP synthase: GLUT-1 (rho = 0.370, 95% CI = 0.0750 to 0.606, p = 0.0157), TKTL1 (rho = 0.460, 95% CI = 0.165 to 0.704, p = 0.0056), SDHA (rho = 0.485, 95% CI = 0.213 to 0.688, p = 0.0011), SDHB (rho = 0.657, 95% CI = 0.441 to 0.801, p < 0.001), and ATP synthase (rho = 0.413, 95% CI = 0.125 to 0.637, p = 0.0065). The gene discussed is TKTL1; the disease is cancer.
