纵向多组学揭示肠易激综合症的特定亚型机制

美国梅奥诊所Purna C. Kashyap、明尼苏达大学Dan Knights等研究人员合作揭示肠易激综合症的特定亚型机制。该项研究成果于2020年9月10日在线发表在《细胞》杂志上。

以肠易激综合征(IBS)宿主生理为背景,研究人员整合了肠道微生物组、代谢组、宿主表观基因组和转录组的纵向多组学数据。研究人员确定了IBS亚型特异性和症状相关的微生物组成和功能变异。鉴定出的微生物代谢物变化类型对应于与IBS相关的宿主生理机制。通过整合多个数据层,研究人员确定嘌呤代谢是IBS中具有转化潜力的新型宿主-微生物代谢途径。这项研究表明,纵向采样与整合互补的多组学数据能够鉴定慢性胃肠道疾病治疗策略的功能机制。
 
据了解,肠道微生物组与多种人类慢性胃肠道疾病有关。由于动物和人类研究之间明显的脱节以及缺乏针对疾病特异性生理变化的综合多组学观点,因此很难确定其在疾病中的作用机理。

Abstract: The gut microbiome has been implicated in multiple human chronic gastrointestinal(GI) disorders. Determining its mechanistic role in disease has been difficult dueto apparent disconnects between animal and human studies and lack of an integratedmulti-omics view of disease-specific physiological changes. We integrated longitudinalmulti-omics data from the gut microbiome, metabolome, host epigenome, and transcriptomein the context of irritable bowel syndrome (IBS) host physiology. We identified IBSsubtype-specific and symptom-related variation in microbial composition and function.A subset of identified changes in microbial metabolites correspond to host physiologicalmechanisms that are relevant to IBS. By integrating multiple data layers, we identifiedpurine metabolism as a novel host-microbial metabolic pathway in IBS with translationalpotential. Our study highlights the importance of longitudinal sampling and integratingcomplementary multi-omics data to identify functional mechanisms that can serve astherapeutic targets in a comprehensive treatment strategy for chronic GI diseases.
