NDRG4 Alleviates Myocardial Infarction-Induced Apoptosis through the JAK2/STAT3 Pathway.
Article in Computational and mathematical methods in medicine, 2022. 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 It has been retracted, and should not be counted.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 3 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
objectiveAt present, studies have confirmed that NDRG4 is specifically expressed in the heart, while its effect on the heart is still unclear. This study is to explore the effect of NDRG4 on cardiomyocyte apoptosis caused by acute myocardial infarction (AMI).
methodsTwenty SD rats were randomly divided into Sham (left anterior descent of heart without ligation) and AMI groups. In this study, coronary artery ligation was used to establish an AMI model, and the AMI model was verified by auxiliary examination and pathological examination. Besides, quantitative real-time polymerase chain reaction (qRT-PCR) and Western blotting (WB) was used to detect the expression level of Bax and Bcl-2 in heart tissues, and NDRG mRNA levels in tissues were also detected. qRT-PCR technology was used to verify the transfection efficiency of NDRG4 in H9C2 cells, and the change of apoptosis level of H9C2 cells was detected by Cell Counting Kit-8 (CCK-8) assay and TUNEL staining; besides, the expression level of apoptosis-related factors was detected by WB and qRT-PCR technology. Simultaneously with the modeling of rats, we injected adenovirus (Ad) into the heart tissue and examined the structural and functional changes of the rat heart. Then, WB technology was used to detect the expression level of the JAK2/STAT3 signaling pathway.
resultsThe heart function and heart structure of rats in the MI group were dramatically worse, and the expression level of NDRG4 was also dramatically reduced. The overexpression of NDRG4 in H9C2 cells can effectively inhibit the ischemia/hypoxia- (I/H-) induced decrease in cell viability and increase in apoptosis rate and inhibit the increase in Bax/Bcl-2 ratio. Moreover, overexpression of NDRG4 in heart tissue can effectively improve the cardiac function and structural destruction caused by MI. In addition, NDRG4 can inhibit JAK2/STAT3 pathway activation.
conclusionThe expression of NDRG4 in the MI tissue of rats was suppressed, while overexpression of NDRG4 by injection of Ad can obviously protect the rat heart. Furthermore, overexpression of NDRG4 in H9C2 cells can effectively inhibit the I/H-induced decrease in cell viability and increase in apoptosis rate, and this may be related to the inhibition of the JAK2/STAT3 signaling pathway.
