整合的乙型肝炎病毒 (HBV) DNA 存在于超过 85% 的 HBV 相关肝细胞癌 (HBV-HCC) 中,在 HBV 相关肝病进展中发挥重要作用。通过整合事件创建的 HBV 宿主连接序列 (HBV-JS) 已用于确定 HBV-HCC 克隆性。在这里,我们研究了在无创尿液液体活检中分析 HBV 整合的可行性。使用 HBV 靶向下一代测序 (NGS) 检测,我们首先在 8 个 HBV-HCC 组织中鉴定出 HBV-JS,并设计了短扩增子连接特异性聚合酶链反应检测来检测匹配尿液中的 HBV-JS。我们在八个匹配的尿液样本中的五个中检测并验证了组织衍生的连接。接下来,我们筛查了从 25 名 HBV 感染患者(5 名肝炎患者、10 名肝硬化患者、4 名 HCC 患者和 6 名 HCC 后患者)收集的 32 份尿液样本。令人鼓舞的是,所有 32 个尿液样本均含有可通过 HBV 靶向 NGS 检测到的 HBV-JS。在尿液中检测到的 712 个 HBV-JS 中,有 351 个位于基因编码区,其中 11 个基因编码区,包括 TERT(端粒酶逆转录酶),此前曾被报道为 HCC 组织中的复发整合位点,并且仅在肝硬化或 HCC 患者的尿液中发现。尿液中检测到的 HBV DNA 整合断点主要(约 70%)位于先前确定的整合热点 HBV DR1-2(转录 1-2 的下调因子)处。结论:乙型肝炎病毒感染者尿液中可检出乙型肝炎病毒-宿主连接DNA。这项研究证明了对整合的 HBV DNA 进行无创尿液液体活检来监测 HBV 感染患者是否患有 HBV 相关肝病以及抗病毒治疗的疗效的潜力。
Integrated hepatitis B virus (HBV) DNA, found in more than 85% of HBV‐associated hepatocellular carcinomas (HBV‐HCCs), can play a significant role in HBV‐related liver disease progression. HBV‐host junction sequences (HBV‐JSs), created through integration events, have been used to determine HBV‐HCC clonality. Here, we investigate the feasibility of analyzing HBV integration in a noninvasive urine liquid biopsy. Using an HBV‐targeted next‐generation sequencing (NGS) assay, we first identified HBV‐JSs in eight HBV‐HCC tissues and designed short‐amplicon junction‐specific polymerase chain reaction assays to detect HBV‐JSs in matched urine. We detected and validated tissue‐derived junctions in five of eight matched urine samples. Next, we screened 32 urine samples collected from 25 patients infected with HBV (5 with hepatitis, 10 with cirrhosis, 4 with HCC, and 6 post‐HCC). Encouragingly, all 32 urine samples contained HBV‐JSs detectable by HBV‐targeted NGS. Of the 712 total HBV‐JSs detected in urine, 351 were in gene‐coding regions, 11 of which, including TERT (telomerase reverse transcriptase), had previously been reported as recurrent integration sites in HCC tissue and were found only in the urine patients with cirrhosis or HCC. The integration breakpoints of HBV DNA detected in urine were found predominantly (~70%) at a previously identified integration hotspot, HBV DR1‐2 (down‐regulator of transcription 1‐2). Conclusion: HBV viral–host junction DNA can be detected in urine of patients infected with HBV. This study demonstrates the potential for a noninvasive urine liquid biopsy of integrated HBV DNA to monitor patients infected with HBV for HBV‐associated liver diseases and the efficacy of antiviral therapy.
