FAM30A Induces Inflammation and Oxidative Damage in PDLSCs by Targeting miR-424-5p.
Article in International dental journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo investigate the diagnostic value and regulatory role of FAM30A in patients with chronic periodontitis (CP).
methodsThe study included 104 CP patients. Saliva and periodontal ligament tissue samples were stored at -80°C. Logistic regression predicted risk factors for CP. Periodontal ligament stem cells (PDLSCs) were stimulated with 100 ng/mL LPS to establish an in vitro model. RT-qPCR assessed gene expression. CCK-8 and flow cytometry evaluated cell proliferation and apoptosis. ELISA measured inflammatory cytokine expression, while kits quantified oxidative stress products. Dual luciferase reporter assays and RNA immunoprecipitation examined gene-target relationships.
resultsFAM30A was upregulated in saliva and periodontal ligament tissue from CP patients. FAM30A demonstrated diagnostic value in both sample types and was identified as a risk factor for CP. LPS stimulation increased FAM30A expression in cells. si-FAM30A promoted cell proliferation, reduced apoptosis, and suppressed inflammatory and oxidative stress levels. miR-424-5p was downregulated in CP patients. Furthermore, FAM30A competitively binds miR-424-5p to modulate PDLSCs' function. Transfection with miR inhibitor counteracts si- FAM30A-induced cellular dysfunction and inflammatory responses.
conclusionFAM30A induces CP by targeting miR-424-5p to inhibit PDLSCs proliferation, promote apoptosis, and increase inflammatory and oxidative stress levels.
