The PVT1 locus is hypomethylated and methylation state negatively correlated with its lncRNA expression in CRC. a The methylation levels at the PVT1 locus in CRC and normal mucosa determined using a 450 K methylation array derived from TCGA database. b Methylation levels at the CpG site (cg23898497) in CRC compared to normal mucosa in all stages in Cohort-1 (P < 0.001, AUC = 0.99) according to the FANTOM5 database. c Methylation levels at the CpG site (cg23898497) in CRC compared to normal mucosa in all stages in Cohort-3 (P < 0.001, AUC = 0.81) as determined by pyrosequencing. d Plot of the PVT1 methylation versus its lncRNA expression (ρ = − 0.4894, P < 0.0001), and the PVT1 methylation versus MYC expression (ρ = − 0.3879, P = 0.0005) in Cohort-1. ***P < 0.001
