As we demonstrated that SCD1 inhibitors and siRNA both increased the SFA accumulation in human colorectal cancer LOVO and Colo205 cells as well as in human ovarian cancer SKOV3 cells (Supplementary Fig. 1), while they did not induce SKOV3 cell apoptosis along with obvious endo-ceramide production (Fig. 2, Supplementary Figs 3–6). Here, SCD is linked to ovarian cancer.
