摘要 Abstract

中文摘要
高危型人乳头瘤病毒(hrHPV),尤其是HPV 16和18型,是宫颈癌变的主要病因,该疾病对全球女性造成不成比例的影响,是发病和死亡的主要原因之一。hrHPV编码可破坏细胞周期调控、抑制细胞凋亡并促进恶性转化的癌蛋白。苦荬菜(Launaea cornuta,LC)是一种已知含有黄酮类、萜类和酚酸类成分的药用植物。LC传统上因其抗炎、抗病毒和抗癌特性而受到重视,并已在多种临床前模型中显示出生物活性,提示其在HPV相关病变治疗中的潜在应用价值。我们采用网络药理学方法鉴定hrHPV诱导的宫颈癌中的分子靶点。生物信息学分析表明,LC植物化学成分与关键基因——CASP3(caspase-3)、BCL2(B细胞淋巴瘤2)和HIF1A(缺氧诱导因子1-alpha)——相互作用,这些基因与凋亡和缺氧反应相关。分子对接模拟评估了LC来源化合物与hrHPV癌蛋白(E6和E7)及枢纽基因的结合亲和力。蛋白质结构取自数据库,对接评分用于估计抑制效应。网络药理学分析确定CASP3、BCL2和HIF1A为参与hrHPV诱导宫颈癌发病机制的核心基因。这些基因代表连接病毒致癌、凋亡调控和细胞对缺氧适应的关键节点。若干LC植物化学成分对hrHPV E6/E7癌蛋白及枢纽基因表现出强结合亲和力。分子动力学分析显示,若干LC植物化学成分——如stigmasteryl methyl ether、Tricyclo(20.8.0.0(7,16))triacontane、1(22),7(16)-diepoxy和tremulone——与E6、E7癌蛋白及枢纽基因表现出强结合亲和力(-5.9至-8.4 kcal/mol),提示其在病毒灭活或抑制致癌功能方面的潜力。LC植物化学成分可能通过与病毒和宿主细胞蛋白的靶向相互作用,抑制hrHPV驱动的致癌机制,从而促进凋亡并减少肿瘤进展。它们的治疗潜力通过对涉及CASP3、BCL2和HIF1A的关键通路的调控而得以凸显。对LC植物化学成分的计算机模拟评估表明,其对hrHPV E6和E7癌蛋白以及参与宫颈癌的关键分子靶点具有良好的抑制活性。需要进一步研究以将这些发现转化为临床应用。

High-risk Human Papillomavirus (hrHPV) particularly HPV 16 and 18 is the primary etiological agent for cervical carcinogenesis, a disease disproportionately impacting women globally and a leading cause of morbidity and mortality. hrHPV encode oncoproteins that disrupt cell cycle regulation, inhibit apoptosis, and facilitate malignant transformation. Launaea cornuta (LC) is a medicinal plant known to contain flavonoids, terpenoids, and phenolic acids. Traditionally valued for its anti-inflammatory, antiviral, and anticancer properties, LC has demonstrated bioactivity in various preclinical models, indicating its potential applicability in the management of HPV-related pathologies. We used Network Pharmacology to identify molecular targets in hrHPV-induced cervical cancer. Bioinformatics analyses showed that LC phytochemicals interact with key genes-CASP3 (caspase-3), BCL2 (B-cell lymphoma 2), and HIF1A (hypoxia-inducible factor 1-alpha) -linked to apoptosis and hypoxic response. Molecular docking simulations assessed the binding affinities of LC-derived compounds to hrHPV oncoproteins (E6 and E7) and hub genes. Protein structures were taken from databases, and docking scores were used to estimate inhibitory effects. NP analysis identified CASP3, BCL2, and HIF1A as central genes implicated in the pathogenesis of hrHPV-induced cervical cancer. These genes represent critical nodes linking viral oncogenesis, apoptosis regulation, and cellular adaptation to hypoxia. Several LC phytochemicals exhibited strong binding affinities to hrHPV E6/E7 oncoproteins and the hub genes. MD analysis showed that several LC phytochemicals-such as stigmasteryl methyl ether, Tricyclo(20.8.0.0(7,16))triacontane, 1(22), 7(16)-diepoxy, and tremulone-demonstrated strong binding affinities (-5.9 to -8.4 kcal/mol) with E6, E7 oncoproteins and hub genes, indicating potential for viral inactivation or inhibition of oncogenic function. LC phytochemicals may inhibit oncogenic mechanisms driven by hrHPV through targeted interactions with both viral and host cell proteins, thereby facilitating apoptosis and reducing tumor progression. Their therapeutic potential is highlighted by the modulation of critical pathways involving CASP3, BCL2, and HIF1A. The in-silico evaluation of LC phytochemicals demonstrates promising inhibitory activity against hrHPV E6 and E7 oncoproteins and key molecular targets involved in cervical cancer. Further research is necessary to translate these findings into clinical applications.
