Paeoniflorin-6'O-benzene sulfonate suppresses fibroblast-like synoviocytes proliferation and migration in rheumatoid arthritis through regulating GRK2-Gβγ interaction.
Article in Experimental and therapeutic medicine, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Rheumatoid arthritis (RA) is a chronic autoimmune disease. Enhanced G protein coupled receptor kinase 2 (GRK2) translocation and prostaglandin E4 receptor (EP4) desensitization play a critical role in fibroblast-like synoviocytes (FLS) dysfunction. Paeoniflorin-6'O-benzene sulfonate (CP-25) exerts a protective effect in arthritis in the RA animal models. To demonstrate the role of Gβγ in EP4 desensitization and the mechanisms of CP-25 that protects FLS in RA, RA-FLS and adjuvant-induced arthritis (AA-FLS) were isolated from synovium of RA patients and AA rats. RA-FLS, AA-FLS and MH7A were treated with CP-25, Gβγ agonist and antagonist. The cell membrane expression of EP4, GRK2, and Gβγ were detected using western blot analysis. Co-immunoprecipitation (Co-IP) and immunofluorescence were adopted to detect the interactions of GRK2-Gβγ, GRK2-EP4, and EP4-Gβγ. Cell Counting Kit-8 and Transwell assay were used to analyze the proliferation and migration of the FLS. An increased membrane expression of GRK2 and Gβγ, enhanced GRK2-Gβγ interaction and decreased EP4 membrane expression in the RA synovial tissue were identified.
