EGFR and non-small cell lung carcinoma: For example, exosomal miR-323-3p, miR-1468-3p, miR-5189-5p, and miR-6513-5p were identified as potential biomarkers to discriminate between osimertinib-resistant and osimertinib-sensitive NSCLC patients[87], and exosomal miR-210-3p secreted by osimertinib-resistant HCC827 and PC-9 cells was able to promote epithelial-mesenchymal transition and drug resistance in osimertinib-sensitive, EGFR mutant NSCLC cells[88].
