HADH and neoplasm: Further genes with a role in fatty acid oxidation such as CPT1a, acyl-Coenzyme A dehydrogenases, enoyl-Coenzyme A, hydroxysteroid (17-beta) dehydrogenase 4 and hydroxyacyl-Coenzyme A dehydrogenase/3-ketoacyl-Coenzyme A thiolase were not differentially expressed between normal and tumor tissues (Table 2 and data not shown).
