The hypoxia‐induced exosomes contain more potent oncogenic proteins, such as STAT3 and FAS, inducing cell resistance to cisplatin.[204] The recent evidence indicates that exosomal miR‐301a (exo‐miR‐301a) from hypoxic GBM cells could be transferred to the normoxic cells. The gene discussed is STAT3; the disease is glioblastoma.
