对膀胱癌病因的认识有限,阻碍了降低发病率方面的进展。BK多瘤病毒(BKPyV)是一种常见的儿童感染,可在成人肾脏重新激活,导致病毒尿。在这里,我们使用了一个有丝分裂静止的、分化的、正常的人尿毒素体外模型来研究BKPyV的感染。BKPyV感染后,宿主尿路上皮基因组中APOBEC3A和APOBEC3B蛋白显著升高,脱氨酶活性增强,无嘌呤/无嘧啶位点增多。BKPyV Large T抗原(LT-Ag)通过抑制视网膜母细胞瘤蛋白和激活EZH2、E2F1和FOXM1,刺激细胞重新进入细胞周期,共同推动尿路上皮细胞从G0进入G2期细胞周期。BKPyV感染过程中形成的单链DNA置换环为APOBEC3酶与LT-Ag相互作用提供了底物。这些结果支持成人中重新激活的BKPyV感染是免疫不足人群中膀胱癌的危险因素,包括移植患者和老年人。
Limited understanding of bladder cancer aetiopathology hampers progress in reducing incidence. BK polyomavirus (BKPyV) is a common childhood infection that can be reactivated in the adult kidney leading to viruria. Here we used a mitotically-quiescent, differentiated, normal human urothelialin vitromodel to study BKPyV infection. BKPyV infection led to significantly elevated APOBEC3A and APOBEC3B protein, increased deaminase activity and greater numbers of apurinic/apyrimidinic sites in the host urothelial genome. BKPyV Large T antigen (LT-Ag) stimulated re-entry into the cell cycle via inhibition of Retinoblastoma protein and activation of EZH2, E2F1 and FOXM1, which combined to push urothelial cells from G0 into an arrested G2 cell cycle state. The single-stranded DNA displacement loops formed during BKPyV-infection, provide a substrate for APOBEC3 enzymes where they interacted with LT-Ag. These results support reactivated BKPyV infections in adults as a risk factor for bladder cancer in immune-insufficient populations, including transplant patients and the elderly.
