Several of these bacteria are normal microbiota constituents. The presence of these cancer-potentiating microbes and their access to E-cadherin in evolving tumors demonstrate that a loss of appropriate boundaries and barrier maintenance between host and microbe is a critical step in the development of some tumors.he microbiota adapts to host changes such as inflammation. Adaptation shift microbiota to a vulnerable tissue site. Genotoxin azoxymethane and colon barrierâdisrupting agent dextran sodium sulfate independently result in colon tumors in susceptible mouse strains; combining them accelerates tumorigenesis.
