The rescuable function and mechanism of resveratrol on As₂O₃-induced hERG K⁺ channel deficiency.
Article in Naunyn-Schmiedeberg's archives of pharmacology, 2014. 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
Arsenic trioxide (As2O3) is used to treat acute promyelocytic leukemia. However, the cardiotoxicity of long QT syndrome restricts its clinical application. Previous studies showed that As2O3 can damage the human ether-a-go-go-related gene (hERG) current via disturbing its trafficking to cellular membrane. This study aimed to investigate whether the As2O3-insulted hERG channel can be rescued by resveratrol, a recognized cardioprotective agent. The whole-cell patch clamp technique was used to record the hERG current and action potential duration. Co-immunoprecipitation and Western blot assay were applied to determine the function of hERG-Hsp70/Hsp90 chaperone complexes and the expression alteration of protein-folding-related proteins, respectively. Compared with treatment of As2O3 alone, co-treatment with resveratrol successfully restored the current and surface expression of hERG and obviously shortened action potential duration in guinea pig ventricular myocytes. Further experiments demonstrate that resveratrol relieved As2O3-caused endoplasmic reticulum (ER) stress by restoring the function of hERG-Hsp70/Hsp90 chaperone complexes and downregulating the protein expression of ER chaperone proteins (calnexin and calreticulin) and activating transcription factor 6. In conclusion, resveratrol was able to rescue the trafficking deficiency and relieve the ER stress (ERS). Our findings suggest that resveratrol has a potential effect to alleviate the adverse effect of As2O3 on cardiotoxicity.
