Dietary fructose regulates hepatic manganese homeostasis in female mice.
Article in Heliyon, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Arginase, an enzyme dependent on manganese (Mn), plays a crucial role in the production of urea and processing of ammonia in the liver. Previous studies have shown that overconsumption of fructose disrupts Mn homeostasis in the liver of male mice. However, the potential sex-specific differences in the impact of fructose on hepatic Mn homeostasis remain uncertain. In this study, we provide evidence that heightened fructose intake disrupts liver Mn homeostasis in female mice. Elevated fructose exposure led to a reduction in liver Mn levels, resulting in decreased arginase and manganese superoxide dismutase (Mn-SOD) activity in the liver of female mice. The underlying mechanism involves the upregulation of carbohydrate-responsive element binding protein (ChREBP) expression and the Mn exporting gene Slc30a10 in the liver in response to fructose consumption. In summary, our findings support the involvement of fructose in liver Mn metabolism via the ChREBP/Slc30a10 pathway in female mice, and indicate that there is no disparity in the impact of fructose on hepatic Mn homeostasis between sexes.
