Circular RNA hsa_circ_0000848 Regulates Cardiomyocyte Proliferation and Apoptosis Under Hypoxia via Recruiting ELAVL1 and Stabilizing SMAD7 mRNA.
Article in Anatolian journal of cardiology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundMyocardial infarction has been recognized globally as a serious problem featured with high mortality and morbidity. In addition, hypoxia represents the central feature of myocardial infarction. Recently, it has been reported that circular RNAs can exert critical functions in the biological processes of diseases. However, the functions of most circular RNAs remain unclear in cells cultured under hypoxic conditions. In this study, we focused on exploring the role of circ_SMAD7 (namely hsa_circ_0000848 in this study) in cardiomyocyte cells cultured under hypoxic conditions to provide a novel insight for future myocardial infarction studies.
methodsFirstly, a real-time quantitative polymerase chain reaction assay was adopted to analyze hsa_circ_0000848 expression. Functional assays were performed to detect the functions of hsa_circ_0000848 in cardiomyocyte cells cultured under hypoxic conditions. Furthermore, mechanism assays were implemented to explore the regulatory mechanism of hsa_circ_0000848.
resultsHsa_circ_0000848 was notably downregulated in hypoxia-induced cardiomyocytes. The silencing of hsa_circ_0000848 hindered the proliferation while accelerating the apoptosis of hypoxia-induced cardiomyocytes cells. Moreover, hsa_circ_0000848 interacted with ELAV-like RNA-binding protein 1 protein to stabilize SMAD family member 7 mRNA. Moreover, SMAD family member 7 overexpression could reverse the suppressive effect of hsa_circ_0000848 knockdown on myocardial infarction progression.
conclusionsOur research was the first in the field to confirm that the hsa_circ_0000848/ ELAV-like RNA-binding protein 1/SMAD family member 7 axis could affect the development of cardiomyocyte cells cultured under hypoxia, indicating that hsa_circ_0000848 might function as a novel biomarker in cells under hypoxia thus laying the groundwork for future study on myocardial infarction.
