Transcription factor GATA1 represses oxidized-low density lipoprotein-induced pyroptosis of human coronary artery endothelial cells.
Article in Clinical hemorheology and microcirculation, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 1 paper.
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
backgroundAtherosclerosis (AS) is defined as a chronic inflammatory disorder underly the pathogenesis of cardiovascular diseases (CVDs). Endothelial pyroptosis is associated with AS-like diseases and other CVDs.
objectiveThis work was designed to expound on the effect of GATA-binding protein 1 (GATA1) on pyroptosis of human coronary artery endothelial cells (HCAECs) in AS.
methodsHCAECs were treated with oxidized-low density lipoprotein (ox-LDL) to establish HCAEC injury models. Plasmids for overexpressing GATA1 or silencing retinoic acid-related orphan receptor α (RORα) were transfected into HCAECs. Thereafter, the mRNA levels of GATA1 and RORα in HCAECs were detected using real-time quantitative polymerase chain reaction. HCAEC viability was examined using the cell counting kit-8 method. The levels of pyroptosis-related proteins NOD-like receptor protein 3 (NLRP3), cleaved-Caspase-1, N-terminal of gasdermin D (GSDMD-N), and pyroptosis-related inflammatory cytokines interleukin (IL)-1β and IL-18 were determined using Western blot and enzyme-linked immunosorbent assays, respectively. The targeting relationship between GATA1 and RORα was verified using the chromatin-immunoprecipitation assay. Then, the rescue experiment was conducted to explore the effect of RORα on pyroptosis of ox-LDL-treated HCAECs.
resultsIn ox-LDL-treated HCAECs, GATA1 and RORα expressions were decreased, HCAEC viability was reduced, and the levels of NLRP3, cleaved-Caspase1, GSDMD-N, IL-1β, and IL-18 were elevated. GATA1 overexpression increased HCAEC viability and attenuated pyroptosis. GATA1 bound to the RORα promoter region to stimulate RORα transcription, and RORα suppression facilitated ox-LDL-induced pyroptosis of HCAECs.
conclusionsGATA1 activated RORα transcription and therefore limited pyroptosis of ox-LDL-treated HCAECs.
