Quantifying the Oligomeric State of hZIP4 on the Surface of Cells.
Article in Biochemistry, 2019. 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
The human (h) zinc transporter ZIP4 is expressed on the plasma membrane and functions to increase cytosolic zinc levels. Mutations in hZIP4 cause the disease acrodermatitis enteropathica. Dysfunction in the regulation of hZIP4 has also been indicated in solid tissue cancers, including pancreatic and prostate cancer. Although structural studies of the extracellular domain and computational modeling of the membrane domain suggest hZIP4 exists as a dimer, the oligomerization status of hZIP4 in the plasma membrane of mammalian cells has not been directly quantified in vivo. Here, the oligomeric state of hZIP4 expressed in HEK293 cells was quantified using fluorescence correlation spectroscopy. hZIP4 was tagged with eGFP, and by comparing brightness values (ε) of monomer and tandem eGFP constructs to that of an hZIP4/eGFP, we show that hZIP4 is a dimer. Determining that hZIP4 is a dimer is an important step toward understanding the function and processing of the protein, which can provide more insight into how diseases affected by hZIP4 occur and can be managed.
