Macrophage Changes and High-Throughput Sequencing in Aging Mouse Intervertebral Disks.

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
Background: Intervertebral disk (IVD) degeneration is associated with lower back pain and aging; however, the mechanisms underlying age-related changes and the changes in macrophage polarization in aging intervertebral disks require further elucidation. The aim of this study was to evaluate changes in macrophages, the differential expression of senescence genes, and their relationship with hub genes in IVDs during aging in mice. Methods: Twenty-eight male wild C57 mice aged 4 weeks were divided into two groups. Four mice per group were selected for high-throughput sequencing and 10 for tail IVD immunohistochemical analysis. Adult and aged mouse IVD specimens were stained with hematoxylin-eosin, Fast Green, and Alcian Blue to determine collagen (Col) 1, Col2, proteoglycan, P16, P21, P53, CD11b, CD86, CD206, IL-1, TGF-β, and IL-4 expression. High-throughput sequencing was performed on adult and aged mouse IVD tissues. Results: Aged mouse IVDs showed reduced height and marked degeneration, with decreased Col2 and proteoglycan expression and increased Col1 expression. The expression of senescence markers, senescence-associated IL-1, TGF-β, and IL-4, and macrophage-related markers, CD11b, CD86, and CD206, increased markedly with age. High-throughput sequencing revealed 1975 differentially expressed genes in adult and aged mice, with 797 genes showing upregulated expression (top five: Conclusions: Disk senescence and reduced height in aged mice are linked to upregulated expression of senescence-associated phenotypes and macrophage polarization markers. These findings suggest that macrophages and differential gene expression play key roles in age-related IVD degeneration, indicating that they can be used as potential targets for therapeutic intervention.
