CALR and lung cancer: In contrast, LINC00473 overexpression promotes NONO‐CRTC interaction, suggesting that LINC00473 facilitates the interaction of NONO and CRTC and subsequently promotes the cAMP‐mediated transcription of various genes.76 Lung cancer patients with high LINC00473 expression had more aggressive pathological behaviours and shorter survival times by enhancing the interaction between NONO and CRTC.76 Another lncRNA, MetaLnc9, is overexpressed in non‐small cell lung cancer (NSCLC), subsequently causing poor prognosis and enhanced metastasis formation in patients with NSCLC.
