Noise-induced hearing loss (NIHL) is a common sensorineural hearing impairment that lacks U.S. Food and Drug Administration-approved drugs. To fill the gap in effective screening models, we used an in silico transcriptome-based drug screening approach, identifying 22 biological pathways and 64 potential small molecule treatments for NIHL. Two of these, afatinib and zorifertinib [epidermal growth factor receptor (EGFR) inhibitors], showed efficacy in zebrafish and mouse models. Further tests with EGFR knockout mice and EGF-morpholino zebrafish confirmed their protective role against NIHL. Molecular studies in mice highlighted EGFR's crucial involvement in NIHL and the protective effect of zorifertinib. When given orally, zorifertinib was found in the perilymph with favorable pharmacokinetics. In addition, zorifertinib combined with AZD5438 (a cyclin-dependent kinase 2 inhibitor) synergistically prevented NIHL in zebrafish. Our results underscore the potential for in silico transcriptome-based drug screening in diseases lacking efficient models and suggest EGFR inhibitors as potential treatments for NIHL, meriting clinical trials.
噪声性听力损失(NIHL)是一种常见的感觉神经性听力障碍,缺乏美国食品和药物管理局批准的药物。为了填补有效的筛选模型的空白,我们使用基于转录组的计算机药物筛选方法,确定了 22 种生物途径和 64 种潜在的用于 NIHL 的小分子治疗方法。其中两种,阿法替尼和佐利替尼[表皮生长因子受体(EGFR)抑制剂],在斑马鱼和小鼠模型中显示出疗效。对 EGFR 敲除小鼠和 EGF-Morpholino 斑马鱼的进一步测试证实了它们对 NIHL 的保护作用。在小鼠中的分子研究强调了 EGFR 在 NIHL 中的关键作用以及佐利替尼的保护作用。当口服给予时,佐利替尼在耳淋巴液中有良好的药代动力学。此外,佐利替尼与 AZD5438(细胞周期蛋白依赖性激酶 2 抑制剂)联合使用在斑马鱼中协同预防 NIHL。我们的结果强调了在缺乏有效模型的疾病中基于转录组的计算机药物筛选的潜力,并提出 EGFR 抑制剂作为 NIHL 的潜在治疗方法,值得进行临床试验。
