Mitophagy Reprograms Lactate Metabolism to Suppress THBS1 via H3K18la Reduction, Alleviating Intervertebral Disc Degeneration.
Article in Research (Washington, D.C.), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Mitophagy alleviates intervertebral disc degeneration (IVDD) by suppressing cGAS-STING and NLRP3 inflammasome-mediated pyroptosis pathways; however, its metabolic regulatory mechanism remains unexplored. Herein, we discovered that mitophagy activator TJ0113 drives metabolic reprogramming characterized by substantially reduced lactate production in senescent nucleus pulposus (NP) cells. This decline directly diminishes histone H3 lysine 18 lactylation (H3K18la), consequently suppressing transcription of the pro-inflammatory gene thrombospondin-1 (THBS1) and blocking downstream inflammatory cascades in IVDD progress. Through combined genetic silencing of THBS1 and pharmacological inhibition of lactate generation, we establish the lactate-H3K18la-THBS1 axis as the essential mechanism mediating mitophagy's anti-inflammatory effects. Our work provides the first evidence that mitophagy orchestrates a metabolic-epigenetic regulatory axis (lactate-H3K18la-THBS1), unveiling novel therapeutic targets for IVDD and paving the way for epigenetic therapies against disc degeneration.
