Here we describe bacterial colonization with the pathobiont Escherichia coli strain NC101, cancer initiation with AOM, bacterial quantification, and histologic assessment of inflammation and cancer.
Treatment with AG also reduced intestinal interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α production and decreased inducible nitric oxide synthase (iNOS) and cyclooxygenase (COX)-2 protein expression in mice with AOM/DSS-induced CAC.
Interestingly, stromal deletion of Imp1 (Dermo1Cre;Imp1(LoxP/LoxP), or Imp1(ΔMes)) in the azoxymethane/dextran sodium sulfate (AOM/DSS) model of colitis-associated cancer resulted in increased tumor numbers of larger size and more advanced histologic grade than controls.
We assessed the effects of high fat (HF) feeding on colonic stem cell maintenance during cancer initiation (AOM induced) and the responsiveness of stem cells to adipokine signaling pathways.
Here, we explored the antitumor effects and mechanisms of embelin on colitis-associated cancer (CAC) using the azoxymethane/dextran sulfate sodium (AOM/DSS) model, with a particular focus on whether embelin exerts its effect through the IL-6/STAT3 pathway.
The AOM/DSS model (n = 23) and IL-10(-/-) mice (n = 8) were applied to monitor malignancy development via endoscopy and to analyze premalignant and malignant stages of CACs.
