PVT1 and cancer: Recent studies indicate that co‐amplification of human MYC proto‐oncogene, bHLH transcription factor (MYC) and PVT1 is correlated in primary human tumors and that the gain of PVT1 long non‐coding RNA (lncRNA) expression is required for high MYC protein levels in 8q24‐amplified human cancer cells (Iwakawa et al., 2013; Tseng et al., 2014; Wolpin et al., 2014).
