In some cancers, the increased expression of FATP2 is correlated with the accumulation of triglyceride-rich lipid droplets and the promotion of metastasis, which may stem from increased FA transport (e.g. used for energy or membrane synthesis) or VLCFA activation for essential metabolic processes (e.g. membrane synthesis or synthesis of regulatory FA metabolites) (16, –, 18). Here, SLC27A2 is linked to cancer.
