Dysregulated autophagy in periodontal ligament stem cells of individuals with type 2 diabetes mellitus and periodontitis.

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
This study aimed to investigate autophagy and its associated mechanisms in periodontal ligament stem cells (PDLSCs) within the inflammatory microenvironment of type 2 diabetes mellitus (T2DM) and periodontitis. Periodontal ligament tissues were obtained from healthy individuals, individuals with T2DM, individuals with chronic periodontitis, and individuals with both T2DM and periodontitis. PDLSCs were isolated, cultured, and treated with the autophagy inhibitor 3-methyladenine (3-MA) and the autophagy activator rapamycin (Rapa). Cell proliferative capacity was evaluated, autophagic activity and organelle damage were assessed using transmission electron microscopy, and the relative expression levels of autophagy-related genes (Beclin-1, LC3 II, P62) were measured using real-time quantitative PCR. Compared to PDLSCs derived from healthy individuals, those from individuals with chronic periodontitis or T2DM exhibited no significant morphological differences but demonstrated reduced proliferative capacity. Treatment with 3-MA and Rapa did not significantly alter proliferative capacity across groups. PDLSCs from individuals with chronic periodontitis and T2DM displayed increased autophagosome formation, more severe organelle damage, and upregulated expression of autophagy-related genes Beclin-1 and LC3 II, while P62 expression was downregulated, compared to PDLSCs from healthy individuals. PDLSCs from individuals with T2DM and periodontitis exhibit excessive autophagy and organelle damage. Autophagy dysregulation in PDLSCs within a diabetic and inflammatory microenvironment may contribute to the severity of periodontal destruction observed in individuals with T2DM.
