Lipid Droplets Metabolism Mediated by ANXA7-PPARγ Signaling Axis Regulates Spinal Cord Injury Repair in Mice.
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 9 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
Spinal cord injury is characterized by high incidence and high disability, and the specific targets and drugs have not yet been explored. Lipid droplet is a type of organelles that regulates lipid metabolism and oxidative stress. And the regulatory mechanisms of lipid droplets on spinal cord injury remain unclear. Herein, it is found that GTPase activation of Annexin A7 (ANXA7) promotes the up-regulation of genes related to lipid droplet formation. ANXA7 can interact with peroxisome proliferator-activated receptor gamma (PPARγ) to enhance the stability of PPARγ, and promote lipid droplet formation and interaction with mitochondria through promoting Perilipin 5 expression. Then, oxidative stress and lipid peroxidation are inhibited due to the promotion of nuclear factor erythroid 2-related factor 2 (NRF2) nuclear translocation and expression of glutathione peroxidase 4 (GPX4). ANXA7 activation promotes lipid droplet formation and mitochondria-lipid droplet interaction by enhancing nuclear translocation of PPARγ, which contributes to inhibiting lipid peroxidation and neuron damage. Furthermore, activation of PPARγ can promote neural function recovery and spinal cord repair in mice. The focus of this study is to investigate the effects of lipid droplets regulated by ANXA7/PPARγ, providing new targets and strategies for spinal cord injury.
