Effects of an Isoquinoline Alkaloids Blend on the Expression of Genes Relevant for Antioxidant Capacity, Barrier Integrity and Inflammation Along the Broiler Gut.
Article in Journal of animal physiology and animal nutrition, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Intensive broiler production may lead to perturbations of gut function and health. The maintenance of intestinal homeostasis in broilers through the use of dietary phytogenic components such as isoquinoline alkaloids (IQs) is an emerging topic of scientific investigations. In this respect, IQs effects on the underlying mechanisms involved in gut antioxidant capacity, barrier integrity and inflammatory response still remain unclear. This study aimed to investigate the effect of dietary administration of an IQs blend on the expression of genes relevant for gut antioxidant response, barrier function, and inflammatory status, along the intestine of 35-days-old broilers. One hundred eighty-two one-day-old Ross 308 broilers were randomly distributed into 2 experimental treatments with 7 replicates of 13 broilers each for 35 d, namely: control treatment (NC) with no IQ addition in the diet and treatment (M) with dietary supplementation at 200 mg/kg diet of an IQs standardized blend. Broiler performance responses did not differ (p > 0.05) among the two treatments. The results showed that M birds had significantly higher (p < 0.05) expression levels for antioxidant capacity, barrier integrity and inflammation-related genes, at the duodenum compared to NC. Furthermore, at the cecal level, treatment M showed significant (p < 0.05) downregulation of TLR (Toll-like receptors) signaling and the subsequent inflammation components, compared to NC. Overall, under the optimal conditions of the trial, there were no significant growth performance benefits of IQs blend dietary addition in broilers diets. Nevertheless, IQs blend promoted gut homeostasis in 35-days-old broilers via the beneficial modulation of antioxidant and inflammatory responses, primarily at the duodenal level. The latter, under stress challenge conditions, may prove beneficial also for performance that needs to be specifically studied.
