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

backgroundMitophagy plays a critical role in the pathology of Parkinson's disease (PD) via mitochondrial quality control, making it a promising therapeutic target. However, the precise mechanistic role of mitophagy in PD pathogenesis and progression remains unclear.

methodsWe conducted a bioinformatic analysis to identify hub mitophagy-related differentially expressed genes (hub-MPDEGs). The mRNA expression levels of these identified genes were validated using two single-cell RNA sequencing datasets (GSE178265 and PRJNA1145007) and further confirmed in an α-synuclein A53T transgenic mouse model.

resultsFive hub-MPDEGs were identified: CANX, GABARAPL1, HSPD1, PPARGC1A, and TOMM20. Transcriptomic analysis revealed elevated abundance of these genes in α-synuclein A53T mice compared to controls. Single-cell resolution analysis demonstrated significant differential expression of these genes in astrocytes, dopamine neurons, glutamatergic neurons, endothelial cells, and oligodendrocyte precursor cells within the substantia nigra of PD samples compared to controls. Furthermore, significant differences in mRNA levels were observed in peripheral immune cells, specifically CD4+ T cells, CD8+ T cells, monocytes, and NK cells, between control and PD samples.

conclusionsThis study identifies and validates five key mitophagy-related genes that are differentially regulated in the central nervous system and peripheral immune cells in the context of Parkinson's disease. These findings highlight the systemic nature of mitophagy dysregulation in PD.
