ITGA2B and cancer: As shown in Figure 10, it is evident that Eu ion incubated with Hela cells stimulated the receptor in the cell membrane, inducing the up-regulation of ITGA2B to enter the cell membrane by utilizing calcium ion channel, then in the cytoplasm, the process of molecular precursor (Eu ion) to fluorescent Eu complex in cancer cells could readily occur, where a lot of genes were up-regulation which involved in cell recognition, cell proliferation, cell migration and relevant biosynthetic process.
