炎症性肠病或结直肠癌(CRC)患者体内有大量的肠道细菌,尤其是大肠杆菌。然而,目前还不清楚癌症是由炎症诱导的大肠杆菌扩张和/或特定微生物基因表达的变化引起的。在这里,我们使用来自无菌小鼠的管腔微生物区系的纵向(2,12和20周)16SRRNA测序,表明发炎的Il10−/−小鼠比健康的野生型小鼠保持更多的肠杆菌科细菌。用单克隆的Il10−/−小鼠进行的实验表明,宿主炎症是大肠杆菌促癌活性所必需的。序列分析表明,Il10−/−小鼠的大肠杆菌基因目录发生了显著变化,这些变化主要是由于对肠道环境的适应所致。在促进肿瘤的大肠杆菌PKS岛上存在的特定基因的表达受炎症/CRC发展的调节。因此,I10−/−小鼠的炎症进展支持肠杆菌科细菌,并改变了对肿瘤发展至关重要的一小部分微生物基因。
Enterobacteria, especially Escherichia coli, are abundant in patients with inflammatory bowel disease or colorectal cancer (CRC). However, it is unclear whether cancer is promoted by inflammation-induced expansion of E. coli and/or changes in expression of specific microbial genes. Here we use longitudinal (2, 12 and 20 weeks) 16S rRNA sequencing of luminal microbiota from ex-germ free mice to show that inflamed Il10−/− mice maintain a higher abundance of Enterobacteriaceae than healthy wild-type mice. Experiments with mono-colonized Il10−/− mice reveal that host inflammation is necessary for E. coli cancer-promoting activity. RNA-sequence analysis indicates significant changes in E. coli gene catalogue in Il10−/− mice, with changes mostly driven by adaptation to the intestinal environment. Expression of specific genes present in the tumor-promoting E. coli pks island are modulated by inflammation/CRC development. Thus, progression of inflammation in Il10−/− mice supports Enterobacteriaceae and alters a small subset of microbial genes important for tumor development.
