G604S-HERG mutation in LQT2 leads to autophagy via the UPR-related pathway.
Article in Journal of biosciences, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
Congenital long QT syndrome (LQTS) is a heart channel disease associated with fatal ventricular arrhythmias or cardiac arrest. Human ether-a-go-go-related gene (HERG) mutation is one of the main causes in type 2 LQTS since it may lead to abundant immature HERG channel protein accumulate in the endoplasmic reticulum (ER). In our study, we have successfully constructed the G604S-HERG mutation in HEK293 cells and demonstrated that the immature HERG protein on ER via Western blot and immunofluorescence. Herein we found that unfolded protein reaction (UPR) process has been activated in order to counter this endoplasmic reticulum stress (ERS) since the main sensors got upregulated. Meanwhile, autophagy was also observed in this process and verified by Western blot and transmission electron microscopy. To explore the relationship underlying autophagy and UPR in the condition of ERS, we found that PERK-EIF2a-CHOP axis was activated. Our findings provides insight for G604S-HERG mutation in type 2 LQTS.
