Circ_0008285 silencing suppresses angiotensin II-induced vascular smooth muscle cell apoptosis in thoracic aortic aneurysm via miR-150-5p/BASP1 axis.
Article in Thoracic cancer, 2023. 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
backgroundVascular smooth muscle cells (VSMCs) are the predominant cell type of the aortic middle layer, the abnormal number or function of which has been demonstrated to have a role in thoracic aortic aneurysm (TAA). Here, this study aimed to identify the function of circ_0008285 in VSMC apoptosis.
methodsHuman VSMCs were treated with angiotensin II (Ang II) for functional experiments. Cell counting kit-8, 5-ethynyl-2'-deoxyuridine (EdU), and flow cytometry were applied for function analysis. The interaction between miR-150-5p and circ_0008285 or brain acid-soluble protein 1 (BASP1) was also evaluated by dual-luciferase reporter assay and RNA immunoprecipitation assay. Exosomes were isolated by the commercial kit.
resultsA highly expressed circ_0008285 was observed in the aortic tissues of TAA patients and Ang-II-induced VSMCs. Circ_0008285 deficiency dramatically reversed Ang-II-induced proliferation arrest and apoptosis promotion in VSMCs. Circ_0008285 functionally targeted miR-150-5p. MiR-150-5p inhibition attenuated the inhibitory effects of circ_0008285 silencing on Ang-II-evoked apoptosis in VSMCs. BASP1 was verified to be a target of miR-150-5p, and was proved to attenuate miR-150-5p-triggered apoptosis arrest in Ang-II-stimulated VSMCs. Additionally, extracellular circ_0008285 was packaged into exosomes, which could be transferred into the recipient cells.
conclusionCirc_0008285 silencing could suppress Ang-II-induced VSMCs apoptosis via miR-150-5p/BASP1 axis, adding further understanding of the pathogenesis of TAA.
