Nat Commun:机器学习助力药物再利用治疗阿尔茨海默病

2021-02-16 haibei MedSci原创

最近,研究人员在Nature Medicine杂志发文,提出了DRIAD(Drug Repurposing In AD),这是一个机器学习框架,它量化了AD严重程度(Braak阶段)的病理和分子机制之

随着全球人口老龄化的进程,阿尔茨海默病(AD)成为一个日益严重的医疗危机,其主要风险因素是预期寿命延长。据估计,在缺乏有效的预防和治疗方案的情况下,该病的发病率将在未来几十年内增加一倍以上。除了对人类健康和福利的直接影响外,受影响的个人的长期护理也带来了巨大的经济负担。

多方正在努力开发AD的疾病治疗疗法,包括迄今为止约200项临床试验,但是目前其结果基本上都是负面的,许多失败的原因是缺乏疗效或毒性过大。每一项新分子实体(NME)的临床试验失败都会消耗大量的时间和资源。相比之下,将食品和药物管理局(FDA)已经批准的药物重新用于不同的适应症,成本较低,可能的毒性比较明确,并且与开发NME相比,成功率更高(30%)。

最近,研究人员在Nature Medicine杂志发文,提出了DRIAD(Drug Repurposing In AD),这是一个机器学习框架,它量化了AD严重程度(Braak阶段)的病理和分子机制之间的潜在关联

80种FDA批准并经过临床测试的药物被应用于分化的人类神经细胞培养物,并收集了其扰动所产生的基因列表,DRIAD被用于分析该基因列表,产生一个可能的再利用候选药物的排名列表。

然后,研究人员对得分最高的药物进行检查,寻找其靶点之间的共同趋势。

DRIAD方法可能可以用于提名药物,这些药物在经过额外的验证和相关药效学生物标志物的识别后,可以很容易地在临床试验中进行评估。
