VEGFA, MYC, and JUN are abnormally elevated in the synovial tissue of patients with advanced osteoarthritis.
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 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
Osteoarthritis (OA), affecting > 500 million people worldwide, profoundly affects the quality of life and ability to work. The mitogen-activated protein kinase (MAPK) signaling pathway plays an essential role in OA. To address the lack of studies focused on synovial cells in OA, we evaluated the expression patterns and roles of the MAPK signaling pathway components in OA synovial tissues using bioinformatics. The JUN, MYC, and VEGFA expression levels were significantly higher in the synovial tissues of patients with OA than in control tissues. These loci were closely related to abnormal proliferation, inflammation, and angiogenesis in the synovial tissues of patients with OA. We speculate that Myc and VEGFA activate the p38-MAPK signaling pathway to further activate Jun, thereby promoting abnormal inflammation, proliferation, and angiogenesis in OA synovial tissue. The high MYC, JUN, and VEGFA expression was positively correlated with the patients' K-L score, pain time, and synovial score. Furthermore, the high p38-MAPK and P-p38-MAPK expression confirmed that the abnormal expression and activation of the MAPK signaling pathway occurred in the synovial tissue of patients with OA. Our findings may provide a new direction for the clinical diagnosis and treatment of OA and insights into its pathogenesis.
