PCAT1 and cancer: Although several studies have revealed that lncRNAs on 8q24, including PRNCR1, CCAT2 and PCAT1, encompass the cancer predisposition SNPs (Guo et al., 2019; Ling et al., 2013; Wang & Wang, 2019; Yang et al., 2019), the prognostic significance of these lncRNAs in GC patients has not yet been fully explored.
