Circ_PVT1 is derived from plasmacytoma variant translocation 1 gene (PVT1), and the high expression of circPVT1 in gastric cancer tissues is due to the enlargement of its genomic locus and can promote cell proliferation through the sponge action of miR‐125.42 The expression level of circPVT1 can be used as an independent prognostic biomarker for gastric cancer patients in terms of overall survival (OS) and disease‐free survival.42 Therefore, circPVT1 may become a prognostic biomarker of gastric cancer. This evidence concerns the gene PVT1 and gastric cancer.
