Characteristics

PVT1 gene is 1957 bp long intergenic non-coding RNA and harbors nine exons (GenBank), located on human chromosome 8q24.21 telomeric to the c-Myc gene and it is frequently involved in the translocations occurring in variant Burkitt's lymphomas and murine plasmacytomas[1].

PVT1 gene contains two non canonical Myc-binding sites (E-box CACGCG) in the promoter region proximal to the transcriptional start site (−155/−95) the consensus and the surrounding sequences are conserved in the homologous mouse and rat genes[1].

Function

Schematic representation of PVT1 involvement in ECM deposition. . Hyperglycemia causes an excessive accumulation of extracellular matrix (ECM) in the glomerular mesangium which constitutes the major pathological feature of the glomerulosclerosis or glomerular fibrosis. Hyperglycemic conditions induce an increase in PVT1 expression in MC which contributes to the increase of the two main ECM components, FN1 and COL4A1, as well as the two main regulators of ECM accumulation in the glomerule, PAI-1 and TGFB1. [2].

PVT is involved in diabetic neuropathy and tumorigenesis by affecting the protein stability of the MYC proto-oncogene [1][2].

PVT1 is a downstream target of both c-Myc and N-Myc genes [1].

The E-boxes region in the PVT1 proximal promoter is important for PVT1 transcriptional regulation by Myc proteins and reveal a novel cross-talk between PVT1 and N-Myc in neuroblastoma cells [1].

PVT1 mediate the development and progression of diabetic nephropathy through mechanisms involving ECM accumulation. PVT1 knockdown significantly reduced mRNA and protein levels of the major ECM proteins, FN1 and COL4A1, and two key regulators of ECM proteins, TGFB1 and PAI-1 [2].

PVT1 modulates thyroid cancer cell proliferation by recruiting EZH2 and regulate thyroid-stimulating hormone receptor (TSHR) [3]

PVT1 regulates prostate cancer cell growth by inducing the methylation of miR-146a [4]

C-MYC and PVT1 CNG promotes a malignant phenotype of malignant pleural mesothelioma (MPM), with C-MYC CNG stimulating cell proliferation and PVT1 both stimulating proliferation and inhibiting apoptosis [5].

PVT1 promotes cell proliferation in gastric cancer by epigenetically regulating p15 and p16 [6]


Expression

PVT1 is upregulated in gastric cancer.[7]

PVT1 expression was significantly upregulated by glucose treatment in human mesangial cells [2].

PVT1 is upregulated in thyroid tissues compared with that in adjacent tissues and was up-regulated in IHH-4, FTC-133, and 8505C cell lines compared to controls [3].

PVT1 is overexpressed in prostate cancer, non small cell lung cancer (NSCLC) and hepatocellular carcinoma (HCC) [4][8][9].

PVT1 is significantly upregulated in pancreatic cancer tissues (PCT) and overexpression of PVT1 is associated with poor prognosis in pancreatic cancer patients [10][11]
