SCD and cancer: Saturated and monounsaturated fatty acids (SFA and MUFA) make part of the de novo biosynthesis, involving the enzymatic complex of fatty acid synthase (FASN) and the activity of delta-9 desaturase (Δ9D, stearoyl-CoA desaturase, SCD-1), and both enzymes are overexpressed in cancer, attracting interest for their inhibition [7,8].
