Glucocorticoid induces GSDMD-dependent pyrolysis in PC12 cells via endoplasmic reticulum stress.
Article in PloS one, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
objectiveThe present study explored whether pyroptosis is involved in the injury process of PC12 cells induced by glucocorticoid (GC) and the regulatory relationship between endoplasmic reticulum stress (ERS) and pyrolysis.
methodsLDH leakage of PC12 cells was detected by LDH assay. The number of dead cells was detected by SYTOX green nucleic acid staining. The levels of IL-1β and IL-18 in the supernatants was detected by ELSIA assay. The expression levels of glucose regulated protein 78 (GRP78), cleaved gasdermin D-NT (cleaved-GSDMD-NT), NLR-pyrin domain-containing 3 (NLRP3) and cleaved-caspase-1 were observed by immunofluorescence staining and western blot.
resultsThe LDH assay revealed that GC exposure significantly increased the release of LDH. The results of SYTOX green acid staining showed that GC exposure significantly increased the number of SYTOX green acid-positive cells. The ELSIA assay revealed that GC exposure significantly increased the levels of IL-1β and IL-18 in the supernatants. The results of immunofluorescence staining and western blot showed that GC exposure significantly increased the expression of GRP78, cleaved-GSDMD-NT, NLRP3 and cleaved caspase-1. Treatment with the ERS inhibitor tauroursodeoxycholate (TUDCA) and siRNA GSDMD attenuated related damage and downregulated the expression of the abovementioned proteins.
conclusionThe present study clearly demonstrated that GC exposure can induce GSDMD-dependent pyrolysis, and ERS is involved in the above damage process.
