Analysis and identification of mitochondria-related genes associated with age-related hearing loss.
Article in BMC genomics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
backgroundTo explore the mitochondrial genes that play a key role in the occurrence and development of age-related hearing loss (ARHL) and provide a basis for the study of the mechanism of ARHL.
results503 differentially expressed genes (DEGs) were detected in the GSE49543 dataset. 233 genes were up-regulated, and 270 genes were down-regulated. There are 1140 genes in the mitochondrial gene bank, and 28 differentially expressed genes related to ARHL. These genes are mainly involved in mitochondrial respiratory chain complex assembly, small molecule catabolism, NADH dehydrogenase complex assembly, organic acid catabolism, precursor metabolites and energy production, and mitochondrial span Membrane transport, metabolic processes of active oxygen species. Then, Cytoscape software identified the three key genes: Aco2, Bcs1l and Ndufs1. Immunofluorescence and Western blot experiments confirmed that the protein content of three key genes in aging cochlear hair cells decreased.
conclusionWe employed bioinformatics analysis to screen 503 differentially expressed genes and identified three key genes associated with ARHL. Subsequently, we conducted in vitro experiments to validate their significance, thereby providing a valuable reference for further elucidating the role of mitochondrial function in the pathogenesis and progression of ARHL.
