摘要/Abstract

摘要： 目的探究黄芩素对顺铂所致的耳蜗毛细胞损伤的作用及其潜在分子机制。方法以小鼠听觉毛细胞系(house ear institute-organ of corti 1, HEI-OC1)及离体培养的小鼠耳蜗组织为模型,采用CCK-8法、细胞显微成像和细胞活死染色评估黄芩素对顺铂所致细胞毒性的影响;通过免疫荧光染色检测耳蜗毛细胞存活率;结合实时荧光定量PCR(real-time quantitative polymerase chain reaction, RT-qPCR)、流式细胞术、蛋白质免疫印迹等技术分析黄芩素拮抗顺铂耳毒性的具体机制。结果黄芩素可显著抑制顺铂诱导的HEI-OC1细胞死亡(P<0.001),且在离体耳蜗模型中无细胞毒性。与顺铂单药组相比,黄芩素联合治疗组的毛细胞存活率提高(P=0.000 5)。黄芩素能有效减少线粒体超氧化物及细胞内总活性氧积累,下调促凋亡蛋白Bax、上调抗凋亡蛋白Bcl-2的表达,并抑制Caspase-3/9的活化。结论黄芩素通过减轻线粒体氧化应激,拮抗顺铂诱导的耳蜗毛细胞凋亡,为顺铂耳毒性的防护提供了潜在治疗策略。

Abstract: Objective The objective of this study is to investigate the protective effects of baicalein against cisplatin-induced cochlear hair cell damage and to elucidate its underlying molecular mechanisms. Methods Utilizing the mouse auditory hair cell line(house ear institute-organ of corti 1, HEI-OC1)and ex vivo cultured mouse cochlear tissues as models, the impact of baicalin on cisplatin-induced cytotoxicity were assessed via Cell Counting Kit-8 assay, microscopic imaging, and live/dead cell staining. The survival of cochlear hair cells were evaluated through the use of immunofluorescence staining. To this end, mechanistic studies were conducted using real-time quantitative polymerase chain reaction(RT-qPCR), flow cytometry, and Western blot(WB)analysis. Results The finding revealed that baicalein significantly attenuated cisplatin-induced HEI-OC1 cell death(P<0.001)without exhibiting toxicity in the ex vivo cochlear model. In comparison with the cisplatin-only group, the baicalein co-treatment group exhibited a significant increase in hair cell survival(P=0.000 5). Mechanistic investigations revealed that baicalein effectively reduced mitochondrial superoxide and total intracellular reactive oxygen species accumulation, Furthermore, baicalein was found to downregulate the pro-apoptotic protein Bax, upregulated the anti-apoptotic protein Bcl-2, and suppressed Caspase-3/9 activation. Conclusion Baicalein has been shown to counteract cisplatin-induced cochlear hair cell apoptosis by attenuating mitochondrial oxidative stress. This finding suggests that balcalein could serve as a promising therapeutic agent for preventing cisplatin-induced ototoxicity.
