1 · What the graph read from it

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.

2 · The registry

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

Oligomerization of G-protein-coupled receptors (GPCRs) is emerging as a mechanism for regulation and functional modification, although it has been studied most extensively for Family A receptors. Family B receptors have clear structural differences from Family A. In this paper, we have systematically evaluated GPCRs that are capable of association with the prototypic Family B secretin receptor. All of the receptor constructs were shown to traffic normally to the plasma membrane. We utilized receptor bioluminescence resonance energy transfer (BRET) to determine the presence of constitutive and ligand-dependent receptor association. Extensive intra-family and no cross-family association was observed. Of the nine Family B receptors studied, all constitutively yielded a significant BRET signal with the secretin receptor, except for the calcitonin receptor. Each of the associating hetero-oligomeric receptor pairs generated a BRET signal of similar intensity, less than that of homo-oligomeric secretin receptors. BRET signals from some receptor pairs were reduced by ligand occupation, but none were increased by this treatment. Thus, Family B GPCR oligomerization occurs, with many structurally related members associating with each other. The specific functional implications of this need to be further evaluated.
