Phosphoglucose isomerase directs the inflammatory response, calcium influx and fibroblast migration in keloids.
Article in Future science OA, 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
aimKeloids are regarded as an inflammatory skin disease with altered metabolic demands. Calcium ions are known to regulate cell movement. Phosphoglucose isomerase (PGI) not only balances glucose metabolism but also acts as a multifunctional cytokine, as those calcium ions do. Here, for the first time, we aimed to explore the intracellular calcium level controlled by PGI in keloid fibroblasts (KFs) and normal fibroblasts (NFs). In addition, whether PGI regulates the biological functions of KFs via the inflammatory status was investigated.
methodsThe inflammatory status, fibrotic activity, and migration ability of KFs and NFs were evaluated via RT-PCR, western blot analysis, and scratch assay. We inhibited PGI with erythrose 4-phosphate (ER4P) to determine whether PGI regulates KF migration.
resultsThe upregulation of PGI expression was measured in both KFs and keloid tissues. Suppressing PGI inhibited SMA and type I collagen expression, and cell migration in KFs. Indeed, PGI regulated inflammation and calcium influx in KFs.
conclusionsOur study is the first to show that PGI regulates the migration of KFs via a calcium influx-dependent inflammatory response and that blocking PGI might be a therapeutic strategy for keloids.
