Subgroup analysis showed that the high expression of PVT1 was closely related to the low overall survival rate of patients with clear cell renal cell carcinoma, breast cancer, cervical cancer, colon cancer, epithelial ovarian cancer, gastric cancer, lung cancer, and osteosarcoma.
Further functional experiments indicated up-regulation of PVT1 promoted the GC cell proliferation and invasion, while down-regulation of PVT1 inhibited cell proliferation and invasion.
In this review, we illustrate the various functions of PVT1 during the different stages in the complex process of digestive system tumours (including oesophageal cancer, gastric cancer, colorectal cancer, hepatocellular carcinoma and pancreatic cancer).
This study was to evaluate the expression of PVT1 in GC and further explore its clinical significance.Previous microarray datasets were analyzed to conduct a preliminary screening for candidate lncRNAs of gastric cancer biomarkers in human gastric cancer tissues.
The results demonstrated that plasma UCA1 provided the higher diagnostic performance for detection of GC (AUC = 0.928; P < 0.001) than PVT-1 (AUC = 0.731; P < 0.01).
