We noticed that the amount of nonesterified VLCFA species (FFA 26:0 and FFA 26:1) and VLCFA-TAG species harboring C24:0 or C26:0 as their acyl moiety was significantly decreased in HCT116 colorectal cancer cells transfected with ELOVL1 siRNA (Fig. 5A,C). This evidence concerns the gene ELOVL1 and colorectal cancer.
