Moreover, the authors searched for EXO-miR-260 and -miR-1169 in cancer cell lines showing the same trend and expression as in the serum of patients, suggesting a correlation between downregulation of EXO-miR-260 and mutated EGFR, while upregulation of EXO-mir-1169 may identify patients with wild-type EGFR. This evidence concerns the gene EGFR and cancer.
