Regarding the mechanism by which [123I]BMIPP accumulates in cancer cells, we focused on the fatty acid transporters CD36 and FATPs because LCFAs enter cells through fatty acid transporters of CD36 and FATPs on the cell membrane [23,24,25,26], although there are other fatty acid transporters such as fatty acid binding proteins (FABPs) [27]. Here, GOT2 is linked to cancer.
