Several oncogenic lncRNAs, such as prostate cancer-associated transcript 1 (PCAT-1), SNHG5, BCAR4, GHET1, HOTAIR, plasmacytoma variant translocation 1 (PVT1), metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), urothelial carcinoma-associated 1 (UCA1) and nuclear paraspeckle assembly transcript 1 (NEAT1), as well as some tumor suppressor lncRNAs, have been shown to participate in gastric cancer chemoresistance. This evidence concerns the gene PVT1 and gastric cancer.
