顺铂广泛用于多种恶性肿瘤的化疗。然而,由于毛细胞凋亡导致的不可逆性听力损失,阻碍了顺铂的临床应用。到目前为止,还没有制定出解决这个问题的实用方案。同时,microRNA在保护毛细胞免受顺铂诱导的内耳细胞凋亡中的作用还没有得到广泛的研究。在这项研究中,我们监测了体外顺铂治疗期间miR-183、-96和-182在耳蜗中的周转情况。我们发现,在体外3μM顺铂治疗后,过表达miR-182,而不是miR-183和-96,可以改善毛细胞的存活。我们证明了miR-182的过表达通过抑制FOXO3a的翻译而抑制了内在的凋亡途径。我们的研究为以快速和组织特异性的方式减轻顺铂诱导的毛细胞凋亡提供了新的治疗靶点。
Cisplatin is widely used for chemotherapy of a variety of malignancies. However, the clinical application of cisplatin is hampered by the resultant irreversible hearing loss due to hair cell apoptosis. To date, no practical regimen to resolve this has been developed. Meanwhile, the role of microRNA in protecting hair cells from cisplatin-induced apoptosis in the inner ear has not been extensively investigated. In this study, we monitored miR-183,-96, and-182 turnover in the cochlea during cisplatin treatment in vitro. We found that overexpression of miR-182, but not miR-183 and-96, improved hair cell survival after 3 μM cisplatin treatment in vitro. We demonstrated that overexpression of miR-182 repressed the intrinsic apoptotic pathway by inhibiting the translation of FOXO3a. Our study offers a new therapeutic target for alleviating cisplatin-induced hair cell apoptosis in a rapid and tissue-specific manner.
