Abstract:Obesity is an established risk factor for colorectal cancer (CRC), but the mechanism(s) responsible for this relationship are still not fully understood. We hypothesize that obesity creates a low‐grade colonic inflammatory microenvironment, which facilitates the development of CRC. Our prior study suggested tumor necrosis factor alpha (TNF‐α) might elevate the Wnt‐signaling, and thereby promote the colonic tumorigenesis. In the present study, we observed that several colonic inflammatory cytokines (TNF‐α, IL‐1… Show more
