Age-related decline in nuclear envelope LINC complex drives neuronal aging via axon initial segment dysfunction.
Article in EMBO reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
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 is an intricate process that inevitably leads to functional deterioration. However, its molecular drivers remain unclear. Here, we show that the age-related decline in LINC complex expression on the neuronal nuclear envelope impairs axon initial segment (AIS)-mediated excitability and triggers brain aging. With aging, the expression of LINC complex components, including Sun1, decreases in various brain regions, accompanied by a reduction in AIS length. Preserving Sun1 expression rescues nuclear structural abnormalities in aged neurons, shifting chromatin dynamics and global gene expression toward those of young neurons. Particularly, it restores the expression of AIS-related molecules, including voltage-gated sodium or potassium channels essential for action potential generation. Inhibiting the LINC complex in young mice impairs AIS integrity, leading to reduced neuronal excitability and brain dysfunction. Furthermore, Sun1 administration to aged neurons prevents age-related AIS shortening, excitability impairment, and brain function changes. Thus, we uncover the mechanism of normal brain aging involving AIS dysfunction, identifying the LINC complex component Sun1 as essential for preserving brain function.
