Studies have shown that lipid-enriched cancer cells exhibit increased expression of fatty acid oxidation (FAO) enzymes, such as carnitine palmitoyltransferase 1A (CPT1A) and acyl-CoA synthetase long-chain family member 4 (ACSL4), which sustain ATP production and confer resistance to apoptosis [133]. The gene discussed is CPT1A; the disease is cancer.
