Regarding NSCLC, Niu et al compared exosomes from the sera of 125 patients with NSCLC and 46 healthy donors, and found that exosomes from the patients express significantly more α‐2‐HS‐glycoprotein (AHSG) having a remarkable biantennary structure and presence of extracellular matrix protein 1 (ECM1).44, 45. This evidence concerns the gene AHSG and non-small cell lung carcinoma.
