Exploring the Role of TAS2Rs in Obesity: Insights From Human and Rat Models.

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
objectiveObesity is a chronic disease with various causes and diverse treatments, including dietary restriction and bariatric surgery. Bitter taste receptors (TAS2Rs), found in the oral cavity and gastrointestinal tract (GIT), are implicated in digestive and metabolic regulation, but their role in obesity remains unclear. This study investigates intestinal TAS2R expression concerning obesity and bariatric surgery outcomes.
methodsTASas2r expression was assessed in intestinal segments of female rats fed a cafeteria diet for 17 weeks. Additionally, jejunal TAS2R expression was measured in women with class III obesity, with or without metabolic syndrome (MS), undergoing Roux-en-Y gastric bypass (RYGB). Associations with weight loss at 12 months postsurgery were evaluated.
resultsIn rats, cafeteria diet significantly reduced Tas2r expression, especially in the jejunum and duodenum. In women with MS, higher expression of TAS2R13 and TAS2R20 correlated with greater weight loss post-after RYGB. In those without metabolic syndrome, higher TAS2R5 expression showed similar associations. TAS2R expression was strongly linked to surgical outcomes. In rats, Tas2r108 (ileum) and Tas2r144 (jejunum) expression levels differed between obese and lean animals.
conclusionsIntestinal TAS2Rs may influence metabolic regulation and bariatric surgery outcomes, suggesting their potential as therapeutic targets in female obesity. Further studies should clarify their underlying mechanisms.
