Increased expression of IL-1β in adipose tissue in obesity influences the development of colon cancer by promoting inflammation.

ABSTRACT: Excess adiposity contributes to the development of colon carcinoma (CC). Interleukin (IL)-1β is a pro-inflammatory cytokine relevant in obesity-associated chronic inflammation and tumorigenic processes. We herein aimed to study how obesity and CC affects the expression of IL1B, and to determine the impact of IL-1β on the regulation of metabolic inflammation and gut barrier function in the context of obesity and CC. Samples from 71 volunteers were used in a case-control study and a rat model of diet-induced obesity (DIO). Furthermore, bariatric surgery was used to determine the effect of weight loss on the intestinal gene expression levels of Il1b. To evaluate the effect of IL-1β and obesity in CC, we treated the adenocarcinoma cell line HT-29 with IL-1β and the adipocyte-conditioned medium
