For example, Wang et al. (25) performed qRT-PCR analyses in the NSCLC drug-resistant cell lines, A549/DDP, A549/PTX, and PC9/AB2, and found an ~5-fold, ~4.8-fold, and ~5.5-fold higher expression of SNHG12, respectively, and an ~2.5-fold lower expression of miR-181a compared to their parental cell lines A549 and PC9 (25) (Table 1). Here, SNHG12 is linked to non-small cell lung carcinoma.
