Exosomes from lung cancer mesenchymal cells contain ZEB1 mRNA, which increases the expression of the EMT major transcription factor ZEB1 in recipient cells through the transfer of ZEB1 in exosomes, promoting its transformation from epithelial cells to mesenchymal phenotypes and transferring chemotherapeutic resistance to bronchial epithelial cells [20]. The gene discussed is ZEB1; the disease is lung cancer.
