GUT: 肠道真菌微生物群失调与结直肠癌发生有关

2019-03-08 不详 MedSci原创

人体中细菌和病毒平衡的改变与结直肠癌(CRC)的发生有直接关系。然而,CRC中的肠道真菌微生物群在癌症发生过程中起什么作用仍然不清楚,因此,本项研究的目的是描述CRC中的肠道真菌微生物群的改变及其影响。

目的
人体中细菌和病毒平衡的改变与直肠癌(CRC)的发生有直接关系。然而,CRC中的肠道真菌微生物群在癌症发生过程中起什么作用仍然不清楚,因此,本项研究的目的是描述CRC中的肠道真菌微生物群的改变及其影响。

方法
研究人员分析了184名CRC患者,197名腺瘤患者和204名健康对照受试者的宏基因组序列(发现队列:73名CRC患者和92名对照受试者;验证队列:111名CRC患者,197名腺瘤患者和112名健康人。通过针对整合的微生物参考基因组数据库的精确k聚体比对进行分类法的分配比较。

结果
主成分分析揭示了CRC和对照组在早期和晚期CRC中具有不同的微生物成分(p = 0.0048)。担子菌门:子囊菌的比例较高(p = 0.0042),马拉色菌有所增加(p <0.0001),而酵母菌(p <0.0001)和肺气球菌(p = 0.0017)则相应减少。14个真菌生物标志物的丰度可以用来区分CRC与对照组,AUC为0.93,进一步的生态学分析显示CRC中共存的真菌内部数量和共同排除的细菌 - 真菌相关性的数量更多(p <0.0001)。此外,真菌和细菌之间的共存相互作用,

结论
本研究揭示了CRC相关的真菌生物学失调的现象,其特征是真菌组成和生态学改变,表明肠道真菌可能在CRC中发挥作用。
