Zinc finger protein 275 (ZNF275) is a C2H2-type transcription factor that is localized on chromosome Xq28. Whether ZNF275 participates in modulating the biological behaviors of cervical cancer has not been determined to our knowledge. The present study employed CCK-8, BrdU, flow cytometry, and a transwell assay to investigate the cell viability, proliferation, apoptosis, migration, and invasion of cervical cancer cells. The application of Western blotting and immunohistochemistry (IHC) aims to assess ZNF275 protein expression and identify the signaling pathway relevant to ZNF275-mediated effects on cervical cancer. The therapeutic impact of the combined therapy of the AKT inhibitor triciribine and cisplatin was evaluated on cervical cancer patient-derived xenograft (PDX) models expressing high ZNF275. The current research illustrated that cervical cancer tissue exhibited a higher expression of ZNF275 in contrast to the surrounding normal cervical tissue. The downregulation of ZNF275 suppressed cell viability, migration, and invasion, and facilitated the apoptosis of SiHa and HeLa cells via weakening AKT/Bcl-2 signaling pathway. Moreover, triciribine synergized with cisplatin to reduce cell proliferation, migration, and invasion, and enhanced the apoptosis of SiHa cells expressing high ZNF275. In addition, the combination treatment of triciribine and cisplatin was more effective in inducing tumor regression than single agents in cervical cancer PDX models expressing high ZNF275. Collectively, the current findings demonstrated that ZNF275 serves as a sufficiently predictive indicator of the therapeutic effectiveness of the combined treatment of triciribine and cisplatin on cervical cancer. Combining triciribine with cisplatin greatly broadens the therapeutic options for cervical cancer expressing high ZNF275, but further research is needed to confirm these results.
锌指蛋白275(ZNF275)是一种C2H2型转录因子,定位于X染色体q28。据我们所知,ZNF275是否参与调节宫颈癌的生物学行为尚未确定。本研究采用CCK-8、BrdU、流式细胞术和Transwell实验来研究宫颈癌细胞的活力、增殖、凋亡、迁移和侵袭。应用蛋白质免疫印迹法和免疫组织化学(IHC)旨在评估ZNF275蛋白表达,并确定与ZNF275介导的宫颈癌效应相关的信号通路。在表达高ZNF275的宫颈癌患者来源异种移植(PDX)模型上评估了AKT抑制剂曲西立滨和顺铂联合治疗的疗效。目前的研究表明,与周围正常宫颈组织相比,宫颈癌组织中ZNF275表达更高。ZNF275的下调通过减弱AKT/Bcl-2信号通路抑制细胞活力、迁移和侵袭,并促进SiHa和HeLa细胞的凋亡。此外,曲西立滨与顺铂协同作用以减少细胞增殖、迁移和侵袭,并增强高表达ZNF275的SiHa细胞的凋亡。此外,在表达高ZNF275的宫颈癌PDX模型中,曲西立滨和顺铂联合治疗在诱导肿瘤消退方面比单一药物更有效。总体而言,目前的研究结果表明,ZNF275可作为曲西立滨和顺铂联合治疗宫颈癌疗效的充分预测指标。曲西立滨与顺铂联合使用大大拓宽了高表达ZNF275宫颈癌的治疗选择,但需要进一步研究来证实这些结果。
