本研究的目的是扩大汉族人群中CRC相关微生物组的现有知识,并进一步发现所有人群中人类CRC微生物组的变异模式。利用焦磷酸测序技术对8例中国结直肠癌患者的8对肿瘤/正常组织的细菌16S rRNA基因进行分子监测,分析并表征了结直肠癌相关微生物组的基本特征。首先,我们发现肿瘤相关细菌群落的多样性在增加。其次,在50%的中国结直肠癌患者中,我们发现肿瘤组织中froseburia显著增加(P= 0.017), microbacterium (P= 0.009)和anoxybacillus (P= 0.009)同时减少。结论我们发现了一种新的中国人结直肠癌微生物群模式。在中国结直肠癌患者中,肿瘤部位高分布的脂埋杆菌和肿瘤部位外高分布的微细菌和脱氧杆菌密切相关。在本研究和之前报道的几个人群中,我们观察到人类CRC微生物组与CRC高风险相关的共同和独特模式。
BackgroundThe aim of this study is to expand existing knowledge about the CRC-associated microbiome among Han Chinese, and to further discover the variation pattern of the human CRC microbiome across all population.FindingsUsing pyrosequencing-based molecular monitoring of bacterial 16S rRNA gene from eight tumor/normal tissue pairs of eight Chinese CRC patients, we analyzed and characterized the basic features of the CRC-associated microbiome. Firstly, we discovered an increasing diversity among tumor-associated bacterial communities. Secondly, in 50% of Chinese CRC patients, we found a significant increase ofRoseburia(P= 0.017), and a concurrent decrease of bothMicrobacterium(P= 0.009) andAnoxybacillus(P= 0.009) in tumor tissue.ConclusionsWe discovered a novel CRC microbiome pattern in Chinese. Both the over-representedRoseburiabacteria at tumor sites and the over-representedMicrobacteriumandAnoxybacillusbacteria away from tumor sites were both closely related in Chinese CRC patients. Across several populations reported in this study and previously, we observed both common and distinctive patterns of human CRC microbiome’s association with a high-risk of CRC.
