Qui et al. analyzed the expression profile of a novel lncRNA, CCAT2 (colon cancer-associated transcript 2), in lung cancers, noticing that CCAT2 was significantly over-expressed in NSCLC tissues; in particular, they found that CCAT2 overexpression was associated with adenocarcinomas (P=0.033) but not with squamous cell carcinoma. Here, CCAT2 is linked to squamous cell carcinoma.
