identified that the expression of lncRNA H19 was upregulated in gefitinib-resistant non-small cell lung cancer (NSCLC) cells and that there was a GGAG substrate in the 5′ terminal region, which was bound to hnRNPA2B1 protein to be specifically sorted into exosomes (73). This evidence concerns the gene HNRNPA2B1 and non-small cell lung carcinoma.
