FASN is involved in de novo FA synthesis pathways by elongating of FAs and producing FA palmitate from acetyl-CoA (De Schrijver et al., 2003; Liu et al., 2010), which is required for cell malignant transformation and tumor formation (Bauer et al., 2005; Hatzivassiliou et al., 2005). The gene discussed is FASN; the disease is neoplasm.
