Body-to-brain insulin and Notch signaling regulates memory through neuronal CREB activity.
Article in Nature aging, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
While memory regulation is predominantly understood as autonomous to neurons, factors outside the brain can also affect neuronal function. In Caenorhabditis elegans, the insulin/IGF-1-like signaling (IIS) pathway regulates longevity, metabolism and memory: long-lived daf-2 insulin/IGF-1 receptor mutants more than double memory duration after a single training session, and it was assumed that memory regulation was strictly neuronal. However, here we show that degradation of DAF-2 in the hypodermis also greatly extends memory, via expression of the diffusible Notch ligand, OSM-11, which in turn activates Notch signaling in neurons. Single-nucleus RNA sequencing of neurons revealed increased expression of CREB and other memory genes. Furthermore, in aged animals, activation of the hypodermal IIS-Notch pathway as well as OSM-11 overexpression rescue both memory and learning via CREB activity. Thus, insulin signaling in the liver-like hypodermis non-autonomously regulates neuronal function, providing a systemic connection between metabolism and memory through IIS-Notch-CREB signaling from the body to the brain.
