Fig 2. The roles of FAK in lipid-mediated tumor growth and invasion.
FAK interactions with receptors such as IR/IGF1R/integrin and effectors such as PI3K/Akt/ERK are associated with lipid rafts. Formation and translocation of FAK-associated lipid complexes contributes to ACLY and FASN activation, channeling TCA-processed glucose to promote lipogenesis. Excessive lipid biosynthesis can induce cell growth and lipid turnover-mediated motility. Inhibition of ACLY and FASN leads to decreased lipid biosynthesis and tumor growth/invasion.
