Persistent infection with human papillomavirus (HPV) is the primary cause of cervical cancer worldwide. Notably, women co-infected with HPV and human immunodeficiency virus type 1 (HIV-1) have a six-fold higher lifetime risk of developing cervical cancer compared to those without HIV, even when adhering to antiretroviral therapy (ART) and achieving T-cell reconstitution. While chronic HIV-1 infection is known to cause inflammation, how paracrine signals from immune cells alter signaling in cervical cells remain poorly understood. To address this, we conducted global transcriptomics analysis on cervical swabs from Kenyan women with HPV, stratified by HIV-1 and cancer status. Strikingly, women with HIV-1 showed cancer-like gene expression patterns in non-cancerous cervical epithelial cells. Complementary global mass spectrometry (MS) proteomics of cervical cells exposed to the secretome of HIV-1 infected primary CD4+ T-cells revealed altered expression of proteins in MAPK, PI3K-AKT, and β-catenin signaling pathways. Integrative network analyses of transcriptomic and proteomic datasets revealed that HIV-1 altered gene expression in key pathways known to drive cervical cancer, including genes commonly mutated in HIV-1-naïve disease. Notably, IRS-1, a key PI3K-AKT pathway activator, was found to be consistently upregulated in both participant samples and cell culture models, as were interferon-stimulated genes. Phosphoproteomics MS analysis confirmed PI3K-AKT pathway activation in cervical cells exposed to conditioned media from HIV-1-infected T-cells. Together, our findings uncover how HIV-1 reshapes cervical cell signaling via paracrine mechanisms and highlights the PI3K pathway as a potential therapeutic target in HIV-associated cervical cancer.
人乳头瘤病毒(HPV)的持续感染是全球宫颈癌的主要病因。值得注意的是,与未感染HIV的女性相比,同时感染HPV和1型人类免疫缺陷病毒(HIV-1)的女性患宫颈癌的终生风险高出六倍,即便她们坚持抗逆转录病毒疗法(ART)并实现了T细胞重建。虽然已知慢性HIV-1感染会引发炎症,但免疫细胞的旁分泌信号如何改变宫颈细胞中的信号传导仍知之甚少。为解决这一问题,我们对肯尼亚感染HPV的女性宫颈拭子进行了全转录组学分析,并根据HIV-1和癌症状态进行分层。令人惊讶的是,感染HIV-1的女性在非癌性宫颈上皮细胞中表现出类似癌症的基因表达模式。对暴露于HIV-1感染的原代CD4+ T细胞分泌组的宫颈细胞进行的补充性全蛋白质组质谱(MS)分析显示,丝裂原活化蛋白激酶(MAPK)、磷脂酰肌醇-3激酶-蛋白激酶B(PI3K-AKT)和β-连环蛋白信号通路中的蛋白质表达发生了改变。对转录组和蛋白质组数据集的综合网络分析表明,HIV-1改变了已知驱动宫颈癌的关键信号通路中的基因表达,包括在未感染HIV-1疾病中常见突变的基因。值得注意的是,关键的PI3K-AKT信号通路激活剂胰岛素受体底物1(IRS-1)在参与者样本和细胞培养模型中均持续上调,干扰素刺激基因也是如此。磷酸化蛋白质组质谱分析证实,暴露于HIV-1感染的T细胞条件培养基中的宫颈细胞中PI3K-AKT信号通路被激活。总之,我们的研究结果揭示了HIV-1如何通过旁分泌机制重塑宫颈细胞信号传导,并突出了PI3K信号通路作为HIV相关宫颈癌潜在治疗靶点的作用。
