1 · What the graph read from it

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.

2 · The registry

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

Emerging evidence suggests that peripheral organs, particularly the liver, may influence brain homeostasis and neurodegenerative diseases. This study investigates the differential expression of Parkinson's disease (PD)-related, oxidative stress, and inflammatory genes in the liver and brain of six-week-old male albino Wistar rats (250-300 g) subchronically exposed to rotenone (ROT, 1.3 mg/kg/day, 35 days, b.w.), a pesticide commonly used to model PD. Relative expression levels were measured using quantitative real-time PCR (RT-qPCR) and western blot. Genes involved in mitophagy (Parkin (PARK2), p = 0.0039), oxidative stress response (Parkinson's disease protein (DJ-1), p = 0.0209), lysosomal function (Low-density lipoprotein receptor-related protein-1 (LRP1), p = 0.0418; ATPase cation transporting 13a2 (ATP13a2), p = 0.0308), and inflammation (Tumour necrosis factor alpha (TNF-α), p = 0.0171) were found upregulated in the brain of ROT-induced rats as compared to control rats, and were also significantly higher than in the liver (p < 0.05). In contrast, significantly higher phosphatase and tensin homolog-induced kinase 1 (PINK1) expression was found in the liver as compared to the brain (p = 0.0198). Notably, these inter-organ differences and transcriptional shifts were absent in the controls. Moreover, the liver exhibited distinct molecular responses, including significant downregulation of ATP13a2 and SNCA (Encoding alpha-synuclein) and overexpression of NFe2-like basic leucine zipper transcription factor 2 (NFe2l2), compared to control rats (p < 0.05). Nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and interferon gamma (IFN-γ) showed no significant changes in either tissue (p > 0.05). These findings demonstrate that distinct molecular alterations in the liver and brain following ROT treatment, including differences in the regulation of genes associated with mitophagy, oxidative stress, proteostasis, and inflammation. Our findings demonstrate tissue-specific molecular associations in the liver and brain within the ROT-induced PD model, providing new insights into the pathophysiology of neurodegeneration and identifying potential biomarkers and therapeutic targets for future studies.
