The apoptosis produced by a thiopheno‐pyrimidine‐based FASN inhibitor (Fasnall) in breast cancer cell lines was a result of malonyl‐CoA accumulation, which is known to decrease carnitine palmitoyl transferase‐1 (CPT‐1) activity but had no effect on FASN expression [93]. This evidence concerns the gene CPT1A and breast carcinoma.
