摘要:

表观遗传学标志物在宫颈癌精准筛查中的应用价值日益凸显。其中配对盒基因1(paired box gene 1,PAX1)和连接黏附分子3(junctional adhesion molecule 3,JAM3)的异常甲基化作为宿主细胞癌变过程中的关键表观遗传事件,能够客观反映宫颈上皮细胞的异常转化状态,成为宫颈癌早期诊断的生物标志物。PAX1通过抑制Wnt/β-联蛋白(β-catenin)等多条致癌通路发挥抑癌作用,其甲基化是癌变早期敏感指标;JAM3与上皮屏障功能及肿瘤侵袭转移密切相关,甲基化水平随病变进展显著升高。二者联合甲基化检测具有较高的敏感度和特异度,显著优于传统细胞学方法,不仅能实现早期精准识别,还可有效分流人乳头瘤病毒初筛阳性者,减少不必要的阴道镜转诊,且该检测适用于“自采样”模式,有利于提升基层及资源有限地区的筛查可及性。此外,PAX1/JAM3联合甲基化检测还能预测宫颈锥切术后病理升级风险,指导个体化治疗决策。未来需通过多中心、大样本临床研究进一步确立PAX1/JAM3甲基化的标准化界值(cut-off值),该联合检测有望作为核心技术整合入宫颈癌筛查指南,推动宫颈癌筛查由“群体普查”向“个体化精准防控”模式重大转变。

Abstract:

The application value of epigenetic biomarkers in the precision screening of cervical cancer is becoming increasingly prominent. Among these, the aberrant methylation of paired box gene 1 (PAX1) and junctional adhesion molecule 3 (JAM3) serves as a key epigenetic event during the malignant transformation of host cells. It can objectively reflect the abnormal transformation state of cervical epithelial cells, establishing itself as a biomarker for the early diagnosis of cervical cancer. PAX1 exerts tumor-suppressive role by inhibiting multiple carcinogenic pathways such as Wnt/β-catenin, and its methylation is a sensitive indicator in the early stages of carcinogenesis. JAM3 is closely related to epithelial barrier function and tumor invasion and metastasis, with its methylation level significantly increasing with disease progression. The combined methylation testing of these two genes exhibits high sensitivity and specificity, significantly outperforming traditional cytological methods. It not only enables precise and early identification but also effectively triages individuals who test positive in primary HPV screening, reducing unnecessary referrals for colposcopy. Furthermore, this test is applicable to the "self-sampling" mode, which helps improve screening accessibility in primary care and resource-limited settings. Additionally, combined PAX1/JAM3 methylation testing can predict the risk of pathological upgrading after cervical conization, guiding individualized therapeutic decisions. In the future, multi-center, large-sample clinical studies are needed to further establish standardized cut-off values for PAX1/JAM3 methylation. This combined testing is expected to be integrated as a core technology into cervical cancer screening guidelines, promoting a major shift in cervical cancer screening from "population-based screening" to a model of "individualized precision prevention and control."
