Increased expression of IL-1β in adipose tissue in obesity influences the development of colon cancer by promoting inflammation.
Article in Journal of physiology and biochemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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 (ACM) from patients with obesity. We showed that obesity (P < 0.05) and CC (P < 0.01) upregulated the transcript levels of IL1B in visceral adipose tissue as well as in the colon from patients with CC (P < 0.01). The increased expression of Il1b in the ileum and colon in DIO rats decreased after weight loss achieved by either sleeve gastrectomy or caloric restriction (both P < 0.05). ACM treatment on HT-29 cells upregulated (P < 0.05) the transcripts of IL1B and CCL2, while reducing (P < 0.05) the expression of the anti-inflammatory ADIPOQ and MUC2 genes. Additionally, IL-1β upregulated (P < 0.01) the expression of CCL2 and TNF whilst downregulating (P < 0.01) the transcript levels of IL4, ADIPOQ and TJP1 in HT-29 cells. We provide evidence of the important role of IL-1β in obesity-associated CC by directly promoting inflammation.
