ZFAS1 and neoplasm: Notably, we found four lncRNAs including NCBP2-AS2, LINC00116, GAS5, and ZFAS1. NCBP2-AS2 did not show any expression differences between normal and tumor tissues in PCa (data not shown), however, it has been reported to be up-regulated in lung squamous cell carcinoma compared to lung adenocarcinoma [24].
