Cervical carcinogenesis is the leading cause of cancer-related deaths in women, and the role of high-risk human papillomavirus (HR-HPV) as a possible risk factor in the development of this cancer is well recognized. Despite the availability of multi-therapeutic approaches, there is still major concern regarding the prevention of metastatic dissemination and excessive tissue injuries. Therefore, it is imperative to develop a safer and more efficient treatment modality. , a natural plant, has shown potential therapeutic properties through its fruit latex when applied to HPV-positive cervical cancer cell lines. However, the mechanisms of action of (fig) latex are not well understood. This study aims to provide a deeper insight into the biological activities of fig latex on human cervical cancer cell lines expressing high-risk HPV types 16 and 18. The data obtained from this study reveal that fig latex influences the expression of genes involved in "Class I MHC-mediated antigen presentation" as well as "Antigen processing: Ubiquitination and Proteasome degradation". These genes play a crucial role in host immune surveillance and the resolution of infection. Notably, Western blot analysis corroborated these findings, demonstrating an increase in the expression of MHC class I in HeLa cells after fig latex treatment. Findings from this study suggest that fig latex may enhance T cell responses against oncogenic HPV, which could be beneficial for the clearance of early-stage cancer.
宫颈癌是导致女性癌症相关死亡的主要原因,高危型人乳头瘤病毒(HR-HPV)是导致这种癌症发生的一个可能的危险因素,这一点已得到广泛认可。尽管有多种治疗方法,但仍非常关注转移性扩散和过度组织损伤的预防问题。因此,开发一种更安全、更有效的治疗方式势在必行。作为一种天然植物,其果实乳胶在用于 HPV 阳性宫颈癌细胞系时显示出了潜在的治疗特性。然而,fig 的乳胶的作用机制尚不清楚。本研究旨在更深入地了解 fig 乳胶对表达高危型 HPV 16 和 18 型的人宫颈癌细胞系的生物学活性。从这项研究中获得的数据表明,fig 乳胶影响“MHC Ⅰ类介导的抗原呈递”和“抗原加工:泛素化和蛋白酶体降解”相关基因的表达。这些基因在宿主免疫监视和感染的清除中起着至关重要的作用。值得注意的是,Western blot 分析证实了这一发现,表明 fig 乳胶处理后 HeLa 细胞中 MHC Ⅰ类的表达增加。本研究结果表明,fig 乳胶可能增强针对致癌 HPV 的 T 细胞反应,这可能有助于清除早期癌症。
