Abstract

Background: REV7 is a multifunctional protein involved in various biological processes, including DNA damage response. REV7 expression in human cancer cells influences sensitivity to DNA-damaging agents, and its high expression level is reportedly associated with a poor prognosis in many carcinomas. However, the significance of REV7 expression in human papillomavirus 16-negative oropharyngeal squamous cell carcinoma (OPSCC) remains unclear.

Methods: REV7 expression was assessed by immunohistochemical analysis in 79 patients with HPV16-negative OPSCC. We evaluated the effects of inhibiting REV7 expression on the proliferation and cisplatin sensitivity of FaDu, an HPV16-negative pharyngeal SCC cell line.

Results: In patients with p16-negative OPSCC, the high-REV7-expression group experienced significantly shorter overall survival than the low-REV7-expression group (p = 0.03) in the Cox regression analysis. Furthermore, REV7-deficient FaDu cells showed suppressed cell growth and enhanced sensitivity to cisplatin in vitro.

Conclusions: REV7 expression is associated with a poor prognosis in HPV16-negative OPSCC.

P16阴性口咽鳞癌中REV7表达的意义

背景：REV7是一种多功能蛋白，参与多种生物过程，包括DNA损伤反应。REV7在人类癌细胞中的表达影响着癌细胞对DNA损伤因子的敏感性，据报道，REV7的高表达水平与许多癌症的不良预后有关。然而，REV7在人乳头瘤病毒16阴性口咽鳞状细胞癌（OPSCC）中表达的意义仍不清楚：通过免疫组化分析评估了79例HPV16阴性口咽鳞癌患者的REV7表达情况。我们评估了抑制REV7表达对HPV16阴性咽部SCC细胞系FaDu的增殖和顺铂敏感性的影响：结果：在p16阴性OPSCC患者中，高REV7表达组的总生存期在Cox回归分析中明显短于低REV7表达组（P = 0.03）。此外，REV7缺陷的FaDu细胞在体外显示出细胞生长受抑制，对顺铂的敏感性增强：REV7的表达与HPV16阴性OPSCC的不良预后有关。
