Potential link of high fat diet and mRNA expression of Alzheimer's disease-related genes in the enteric mucosa of a rat model of Alzheimer's disease.

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
Background: High-fat diet (HFD) consumption is linked to Alzheimer's disease (AD). Identifying changes in the mRNA expression due to the ingestion of HFD in the intestine-often called the second brain due to its dense enteric neurons-could offer insights into AD development and progression. Objective: This study assesses whether the introduction of HFD at adult-age influence expression of AD-related genes in the intestines of Wild-type (WT) or the amyloid precursor protein/presenilin1 (APP/PS1)-overexpressing Transgenic (TG) rats. Methods: Twelve-month-old WT and TG rats (male and female) were fed a control diet (CD; 8% energy from fat), or HFD (45% energy from fat) for six months. Ileal tissues were assessed for the mRNA expression of genes responsible for development/progression of AD. Results: The WT HFD-fed rats (compared to CD-fed rats) showed increased mRNA expression of genes involved in the development of AD. In contrast, the TG HFD-fed female group, showed a higher number of upregulated genes compared to their respective CD-fed TG group. In TG HFD-fed rats there was higher mRNA expression of genes crucial for synaptic transmission such as Conclusions: The consumption of HFD perturbed the expression of enteric genes known to be involved in amyloid-β generation, clearance, and degradation, in a sex-dependent manner.
