ASCL4 and neoplasm: Gene expression of three enzymes involved in various steps of FA activation (Acyl-CoA synthetase long-chain family member 4, Ascl4), transport across the mitochondrial membrane (Carnitine palmitoyltransferase 1A, Cpt1a) and β-oxidation (Acyl-CoA dehydrogenase family, member 11, Acad11) was also evaluated in non-tumour tissues.
