Endosomal trafficking of the G protein-coupled receptor somatostatin receptor 3.
Article in Biochemical and biophysical research communications, 2011. 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
Intracellular trafficking of G protein-coupled receptors (GPCRs) regulates their surface availability and determines cellular response to agonists. Rab GTPases regulate membrane trafficking and identifying Rab networks controlling GPCR trafficking is essential for understanding GPCR signaling. We used real time imaging to show that somatostatin receptor 3 (SSTR3) traffics through Rab4-, Rab21-, and Rab11-containing endosomes, but largely bypasses Rab5 and Rab7 endosomes. We show that SSTR3 rapidly traffics through Rab4 endosomes but moves slower through Rab21 and Rab11 endosomes. SSTR3 passage through each endosomal compartment is regulated by the cognate Rab since expression of the inactive Rab4/S22N, Rab21/T33N, and Rab11/S25N inhibits SSTR3 trafficking. Thus, Rab4, Rab21, and Rab11 may represent therapeutic targets to modulate surface availability of SSTR3 for agonist binding. Our novel finding that Rab21 regulates SSTR3 trafficking suggests that Rab21 may play a role in trafficking of other GPCRs.
