High levels of a comprehensive set of matrix metalloproteinases in endometriotic lesions: validating the key role of cellular senescence in endometriosis pathogenesis.

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
backgroundThis study reveals elevated levels of MMP-1, MMP-2, and MMP-3 in endometriotic lesions, potentially reflecting a senescenceassociated secretory phenotype. No corresponding increase was observed in peritoneal fluid, possibly due to technical or sample-related limitations. These findings support the potential of MMPs as biomarkers and therapeutic targets in endometriosis.
backgroundMMP-1, MMP-2, and MMP-3 are upregulated in endometriotic lesions.
backgroundThe study findings suggest a senescence-associted secretory phenotype in endometriosis.
backgroundThe study findings support targeting senescence pathways in endometriosis.
objectiveTo investigate the roles of cellular senescence and dysfunctional extracellular matrix metalloproteinases (MMPs) in perpetuating chronic inflammation and facilitating the establishment of endometriotic lesions. By analyzing the MMP activity in the endometrial tissue and peritoneal fluid, we aimed to obtain novel insights into the molecular mechanisms underlying endometriosis-related pathophysiology.
methodsThe endometrial tissue and peritoneal fluid samples were collected laparoscopically from 12 women with endometriosis and 16 healthy controls. Gelatin zymography was performed to assess the activity of MMP-2, and multiplex assays were performed to determine the concentrations of MMP-1 and MMP-3 proteins. Statistical analyses were performed using Generalized Linear Models (GzLM) and SPSS software.
resultsGelatin zymography revealed higher pro-MMP-2 activity in endometriotic lesions than in eutopic and control endometrium. However, no differences were observed in peritoneal fluid samples. Additionally, MMP-1 and MMP-3 protein levels were elevated in endometriotic lesions compared with those in the eutopic endometrium, whereas only MMP-3 was increased compared with that in the control. No statistical significance was observed for MMP-2, MMP-1, and MMP-3 in the peritoneal fluid samples.
conclusionIncreased levels of MMP-1, MMP-2, and MMP-3 in endometriotic lesions indicate that endometriosis may have a unique metabolomic signature linked to cell cycle arrest and inflammation. This may contribute to the pathogenesis of endometriosis by facilitating implantation of ectopic endometrium-like tissue in a disturbed immune environment.
