Abstract Background Recent studies have confirmed the integration of the BK polyomavirus (BKPyV) gene into the cellular genome of urothelial carcinomas in transplant recipients, further confirming the correlation between BKPyV and urothelial carcinomas after transplantation. However, the role BKPyV infections play in the biological function of bladder cancer remains unclear. Methods We developed a BKPyV-infected bladder cancer cell model and a mice tumor model to discuss the role of BKPyV infections. Results Our research proves that BKPyV infections promote the proliferation, invasion and migration of bladder cancer cells, while the activation of β-catenin signaling pathway is one of its mediation mechanisms. Conclusions We first described BKPyV infection promotes the proliferation, invasion and migration of bladder cancer. We verified the role of β-catenin signaling pathway and Epithelial-Mesenchymal Transition effect in BKPyV-infected bladder cancer. These results provide meaningful information towards the diagnosis and treatment of clinical bladder cancer.

Abstract Background Prostate cancer (PCa) is a common disease that often occurs among older men and a frequent cause of malignancy associated death in this group. microRNA (miR)-129-5p has been identified as an essential regulator with a significant role in the prognosis of PC. Therefore, this study aimed to investigate roles of miR-129-5p in PCa. Methods Microarray analysis was conducted to identify PCa-related genes. The expression of miR-129-5p and ZIC2 in PCa tissues was investigated. To understand the role of miR-129-5p and ZIC2 in PCa, DU145 cells were transfected with mimic or inhibitor of miR-129-5p, or si-ZIC2 and the expression of Wnt, β-catenin, E-cadherin, vimentin, N-cadherin, vascular endothelial growth factor (VEGF), and CD31, as well as the extent of β-catenin phosphorylation was determined. In addition, cell proliferation, migration, invasion, angiogenesis, apoptosis and tumorigenesis were detected. Results miR-129-5p was poorly expressed and ZIC2 was highly expressed in PCa tissues. Down-regulation of ZIC2 or overexpression of miR-129-5p reduced the expression of ZIC2, Wnt, β-catenin, N-cadherin, vimentin, and β-catenin phosphorylation but increased the expression of E-cadherin. Importantly, miR-129-5p overexpression significantly reduced cell migration, invasion, angiogenesis and tumorigenesis while increasing cell apoptosis. Conclusions The findings of the present study indicated that overexpression of miR-129-5p or silencing of ZIC2 could inhibit epithelial–mesenchymal transition (EMT) and angiogenesis in PCa through blockage of the Wnt/β-catenin signaling pathway.

Abstract BackgroundInsulin-like growth factor 2 (IGF2) mRNA-binding protein 2 (IGF2BP2), as a m6A “reader”, is known to be an oncogene, and its expression is elevated in multiple tumors. However, the role of IGF2PB2 in esophageal squamous cell carcinoma (ESCC) is still unclear. MethodsThis study aims to investigate the role of IGF2PB2 expression in ESCC proliferation, invasion and migration as well as the possible mechanism. IGF2BP2 expression was found to be elevated in ESCC tissues by qRT-PCR, western blotting, and immunohistochemical (IHC) staining. ResultsKnocking down IGF2BP2 expression prevented the proliferation, invasion, migration and epithelial-mesenchymal transition (EMT) of KYSE450 and TE1 cells. Knocking out IGF2BP2 reduced tumorigenesis in vivo. Overexpression of IGF2BP2 was performed, and it was proven that IGF2BP2 had an oncogenic effect in KYSE450 and TE1 cells. Moreover, LY294002, a highly selective inhibitor of PI3K, reversed the effect of IGF2BP2 overexpression on EMT processes. All these results show that the effects of IGF2BP2 on oncogenesis and EMT were clearly exerted via the PI3K/AKT signaling pathway. ConclusionsIn conclusion, this study demonstrates that the oncogenic function of IGF2BP2 is mediated by the PI3K/AKT signaling pathway and is related to EMT in ESCC. In addition, IGF2BP2 can serve as a diagnostic and oncotherapeutic marker in further studies.
