PVT1 and liver cancer: LncRNA plasmacytoma variant translocation 1 (PVT1) is overexpressed and implicated in several types of cancer (Chen et al., 2019; p. 1; Liu and Xu, 2020; Ren et al., 2019; Zhou et al., 2020), and specifically it was demonstrated that its expression can regulate GPX4 expression levels through miR-214-3p suppression to favor ferroptosis inhibition in liver cancer.
