Circ_0057583 facilitates brain microvascular endothelial cell injury through modulating miR-204-5p/NR4A1 axis.
Article in Metabolic brain disease, 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
Lipopolysaccharide (LPS) can induce vascular endothelial injury. Circular RNAs (circRNAs) have been verified to regulate different cellular processes in various diseases. This study intended to explore the potential role and mechanism of circ_0057583 in brain microvascular endothelial cell injury. Human brain microvascular endothelial cells (hBMECs) were exposed to different doses of LPS to induce cell damage. The levels of circ_0057583, microRNA-204-5p (miR-204-5p) and nuclear receptor 4A1 (NR4A1) were detected by quantitative real-time PCR or Western blot assays. Cell viability, apoptosis, inflammation and angiogenesis were assessed by Counting Kit-8 (CCK-8), flow cytometry, enzyme linked immunosorbent assay (ELISA) and tube formation assays. The targeting relationship between miR-204-5p and circ_0057583 or NR4A1 was verified by dual-luciferase reporter assay and RNA immunoprecipitation (RIP) assay. LPS treatment elevated the expression of circ_0057583 and NR4A1, but decreased the expression of miR-204-5p in LPS-induced hBMECs. Downregulation of circ_0057583 abated LPS-induced hBMEC injury by inducing cell proliferation and angiogenesis, as well as inhibiting cell apoptosis, autophagy and inflammation. Circ_0057583 aggravated LPS-evoked hBMEC injury by regulating miR-204-5p. Also, miR-204-5p suppressed LPS-evoked hBMEC damage via targeting NR4A1. Moreover, circ_0057583 sponged miR-204-5p to up-regulate NR4A1 level. Depletion of circ_0057583 alleviated LPS-triggered brain microvascular endothelial endothelial cell injury through modulating miR-204-5p/NR4A1 axis.
