XIST and non-small cell lung carcinoma: Also, lncRNA XIST activates the Wnt/β-catenin signalling pathway through the upregulation of E3 ubiquitin-protein ligase RING1 (RING1) expression by the sponging miR-744 that regulates aggressive proliferation in NSCLC cell lines such as A549, H1299, H23, H522, H460, H1650, and 95D [11].
