ROS-Responsive Wedelolactone Hydrogel Promotes Intervertebral Disc Repair by Disrupting the NF-κB-LCN2 Inflammatory Feedback Loop.
Article in Advanced science (Weinheim, Baden-Wurttemberg, Germany), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
Intervertebral disc degeneration (IVDD) is driven by persistent inflammation-oxidative stress that disrupts annulus fibrosus (AF) homeostasis. Guided by network pharmacology and docking, we prioritized the NF-κB-LCN2 axis as a druggable target of wedelolactone (WDL). To achieve targeted modulation, we engineered a dual-network ROS-responsive hydrogel (WPG) in which a phenylboronic-ester/PVA redox-cleavable network interpenetrates a covalently crosslinked GelMA-elastin matrix, enabling mechanically robust yet stimulus-triggered WDL release. WDL suppressed NF-κB activation and downregulated LCN2 in both macrophages and AF cells. Conditioned-medium co-culture demonstrated that WDL disrupts macrophage-derived LCN2-mediated paracrine amplification, breaking the self-sustaining inflammatory loop. Bulk RNA-seq across both cell types revealed coordinated downregulation of NF-κB - driven chemokine cascades and restoration of adhesion and ECM gene programs following WPG treatment. In a rat AF-defect model, intradiscal WPG administration preserved disc height and T
