It has been reported that exosomes generated from platelets transferred glycoprotein IIb–IIIa (CD41) to the surface of lung cancer cells by inducing the expression of G1/S-specific cyclinD2 in lung cancer cells aiming to promote the phosphorylation of MAPKp4244; also, the exosomes stimulated lung cancer cell proliferation [70]. The gene discussed is CCND2; the disease is lung cancer.
