Identifying Tipping Points during Healthy Brain Aging through Single-Nucleus Transcriptomic Analysis.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Brain aging significantly impairs cognitive and behavioral functions. While some nonlinear aging studies have identified age-specific aging peaks at certain ages, the influence of different cell types on brain aging fluctuations across the lifespan remains unclear. This study, approaching from the interdisciplinary perspective of brain aging and systems dynamics, extends the nonlinear aging analysis to the cellular level, using single-cell transcriptomic data to analyze 45 healthy elderly brain samples aged 29-94 years. Describing cellular and molecular differences in the aging process, neuron proportion is downregulated but relatively stable with low variability after aging, while glial cells are significantly upregulated and highly unstable. Notably, peaks in nonlinear molecular fluctuations are observed in aging at ages 60, 70, and 79. The nonlinear features prompted the introduction of a dynamic network biomarker and the identification of 56-60 years as the tipping point in the brain's healthy aging process, then suggesting that glia predominantly mediate this process and exploring the underlying features and mechanisms. This work investigates the tipping point of aging at single-cell resolution and provides new research strategies for early diagnosis and intervention of aging-related neurological diseases.
