Colon tissue of Il10-/- mice monoassociated with Escherichia coli NC101 or Escherichia faecalis OG1RF (PAMM-077 array)


ABSTRACT: We observed that interleukin-10 knockout (Il10-/-) mice injected with azoxymethane (AOM) and monoassociated with E. coli NC101, but not E. faecalis OG1RF, develop tumors. Histologic inflammation is not different in mice monoassociated with either bacterium. The goal of this experiment is to assess inflammatory cytokine levels in colonic tissue of these mice. 4 germ-free Il10-/- mice were assayed and used as controls. 4 E. coli and 4 E. faecalis monoassociated mice were experimental samples.

Inflammation alters host physiology to promote cancer, as seen in colitis-associated colorectal cancer (CRC). Here, we identify the intestinal microbiota as a target of inflammation that affects the progression of CRC. High-throughput sequencing revealed that inflammation modifies gut microbial composition in colitis-susceptible interleukin-10-deficient (Il10(-/-)) mice. Monocolonization with the commensal Escherichia coli NC101 promoted invasive carcinoma in azoxymethane (AOM)-treated Il10(-/-)  ...[more]
