NATURE:通过肠道细菌及其基因定位人类微生物组药物代谢

2019-06-04 海北 MedSci原创

已有的研究显示,个体在药物反应方面差异很大,这可能会导致治疗延迟和不良反应,引起危险和昂贵的后果。 越来越多的证据表明肠道微生物组对于这种可变性的贡献,但至今为止,其分子机制仍然很大程度上未知。

已有的研究显示,个体在药物反应方面差异很大,这可能会导致治疗延迟和不良反应,引起危险和昂贵的后果。

越来越多的证据表明肠道微生物组对于这种可变性的贡献,但至今为止,其分子机制仍然很大程度上未知。

最近,研究人员测量了76种不同的人类肠道细菌代谢271种口服药物的能力,并发现其中许多药物都能够被微生物化学修饰。

研究人员将高通量遗传学与质谱联用,系统地鉴定药物代谢微生物基因产物。这些微生物组编码的酶可以直接和显着地影响小鼠的肠道和全身药物代谢,并且可以基于其基因组内容解释人类肠道细菌和群落的药物代谢活性。

微生物群基因含量和代谢活动之间的这些因果关系将人际微生物组变异与药物代谢中的人际差异联系起来,这对多种疾病适应症的药物治疗和药物开发具有意义。
