The Importance of Acetyl Coenzyme A Synthetase for ¹¹C-Acetate Uptake and Cell Survival in Hepatocellular Carcinoma

Abstract

The patterns of (18)F-FDG and (11)C-acetate uptake seemed to complement each other in both human HCC and HCC cell lines. Fatty acid synthase expression was seen in cells with high (18)F-FDG or (11)C-acetate uptake, suggesting glucose- or acetate-dependent lipid synthesis. Acetyl CoA synthetase appears to be important in (11)C-acetate uptake and acetate-dependent lipid synthesis for the growth of cancer cells with a low-glycolysis phenotype. Inhibition of acetyl CoA synthetase in these cells may be promising for anticancer treatment.
