Taking this into consideration, Guo et al. [15] investigated the function of the lncRNA taurine-upregulated gene 1 (hereafter referred to as TUG1) and miR-221 in NSCLC progression in SPC-A1 and H520 cell lines, both SPC-A1 and H520 cell lines contain Wild-type (WT) p53. Here, TP53 is linked to non-small cell lung carcinoma.
