Apolipoproteins, the major lipoproteins involved in lipid transport, supply lipids that serve as vital energy sources for high levels of cancer cell proliferation and invasion.[28, 29, 30, 31, 32] We found that only APOC2‐Si inhibited the lactate‐induced increase in extracellular FFAs, but not APOA1‐Si or APOA2‐Si (Figure 3B). Here, APOA1 is linked to cancer.
