For example, macrophage-derived exosomes can overexpress ArfGAP with GTPase domain ankyrin repeat and PH domain 2 (AGAP2) antisense RNA 1 (AGAP2-AS1) or underexpress microRNA- (miRNA-) 296 (miR-296) to enhance the antiradiotherapy capability of lung cancer cells [43]. The gene discussed is AGAP2; the disease is lung cancer.
