Muscone suppresses inflammation and senescence of nucleus pulposus via p53 signalling during intervertebral disc degeneration.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 (IDD) is a major cause of chronic low back pain, the mechanism of which is still unclear. Inflammation-induced extracellular matrix metabolism (ECM) dysregulation in the nucleus pulposus (NP) and NP cell senescence are known to be the key causes of IDD. However, few drugs can reliably alleviate ECM dysregulation and NP cell senescence. Muscone, as the key natural component of musk, is a widely applied antiapoptotic and anti-inflammatory drug. We found Muscone exerts protective effects by inhibiting the expression of ECM catabolism-related genes, cell apoptosis, the cell senescence and senescence-associated secretory phenotype (SASP) in NP cells, which is the key cellular phenotype associated with IDD. We have also shown that muscone can increase the expression of ECM anabolism-related genes and the proliferation of NP cells during inflammation. High-throughput RNA sequencing indicated that muscone protects NP cells mainly by altering the phosphorylation and expression of p53. Further validation confirmed both in vivo and in vitro that muscone could regulate ECM-related genes, cell apoptosis, cell senescence and the SASP by inhibiting p53. In summary, our findings show that muscone protects against the degeneration of nucleus pulposus cells by inhibiting p53 signaling and thus may have therapeutic value for IDD.
