It is tempting to speculate that FA carried by serum albumin could be taken up by cancer cells through macropinocytosis: a non-receptor mediated endocytosis process constituting part of an ancestral strategy used to salvage extracellular nutrients.95, 96 Exosomes can also serve as carriers of FA and are taken up by recipient cells (Figure 3). The gene discussed is ALB; the disease is cancer.
