PVT1 and cancer: PVT1 is one such lncRNA located on chr8q24.21 that is expressed at low levels in normal tissues but is also designated as an oncogene because of its amplification/up-regulation status in multiple cancers (Guan et al, 2007; Tseng et al, 2014) acting as a potential competing endogenous RNA for miRNAs (Li et al, 2017; Wang et al, 2019).
