Genetic Insights Into the Role of Cathepsins in Alzheimer's Disease, Parkinson's Disease, and Amyotrophic Lateral Sclerosis: Evidence From Mendelian Randomization Study.
Article in Brain and behavior, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundPrevious studies have confirmed the significant role of cathepsins in the development of neurodegenerative diseases. We aimed to determine whether genetically predicted 10 cathepsins may have a causal effect on Alzheimer's disease (AD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS).
methodsWe conducted a two-sample bidirectional Mendelian randomization (MR) study using publicly available data from genome-wide association study (GWAS) to assess the causal associations between 10 cathepsins and three neurodegenerative diseases, including AD, PD, and ALS. We employed the following methods, including inverse variance weighting (IVW), MR-Egger, and weighted median (WM). The results were further validated using sensitivity analysis.
resultsThe forward MR analysis results indicate that elevated cathepsin H levels increase the risk of AD (p = 0.005, odds ratio [OR] = 1.040, 95% confidence interval [CI] = 1.011-1.069), elevated cathepsin B levels decrease the risk of PD (p < 0.001, OR = 0.890, 95% CI = 0.831-0.954), and no significant association was found between cathepsin levels and ALS. Reverse MR analysis suggests that there is no causal association between 10 cathepsins and three neurodegenerative diseases.
conclusionOur study provides new genetic insights into the role of cathepsin H in AD and cathepsin B in PD. However, our findings need to be further validated in a wider population, and future research should explore the potential mechanisms of cathepsins in these diseases in order to provide a basis for the development of new therapeutic strategies.
