More recent studies have found that the intronic non-coding RNA (ncRNA) lncRNA-LET plays a role in the regulation of hypoxia-mediated metastasis in squamous cell lung carcinoma [14], intronic ncRNA AK126698 confers resistance to cisplatin by targeting the Wnt pathway [15], and the lncRNA SCAL1 (smoke and cancer-associated lncRNA-1) is associated with tobacco-induced lung cancer [16]. The gene discussed is LUCAT1; the disease is lung carcinoma.
