Moreover, lncRNA-SOX2OT was detected in the exosomes of multiple NSCLC cell lines, including A549, H23, H358, H2030, H1299 and H1155 (Figure S3), providing evidence that lncRNA-SOX2OT might play significant roles in the progression of NSCLC. This evidence concerns the gene SOX2-OT and non-small cell lung carcinoma.
