Based on the expression of these three genes, the cancer cell clusters could be subdivided into SCD high [SCD-Hi (SC 6)], FADS2 high [FADS2-Hi (SC 17)], FASN high [FASN-Hi (SC 11)], SCD/FADS2/FASN high, [Triple-Hi (SC 7)] and SCD/FADS2/FASN low [Triple-low (SC 8)] cancer cells (Figure 2D). The gene discussed is FADS2; the disease is cancer.
