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

The insulin-responsive glucose transporter GLUT4 is targeted to a post-endocytic compartment in adipocytes, from where it moves to the cell surface in response to insulin. Previous studies have identified two cytosolic targeting motifs that regulate the intracellular sequestration of this protein: FQQI(5-8) in the N-terminus and LL(489,490) (one-letter amino acid notation) in the C-terminus. In the present study we show that a GLUT4 chimaera in which the C-terminal 12 amino acids in GLUT4 have been replaced with the same region from human GLUT3 is constitutively targeted to the plasma membrane when expressed in 3T3-L1 adipocytes. To further dissect this domain it was divided into three regions, each of which was mutated en bloc to alanine residues. Analysis of these constructs revealed that the targeting information is contained within the residues TELEYLGP(498-505). Using the transferrin-horseradish peroxidase endosomal ablation technique in 3T3-L1 adipocytes, we show that mutants in which this C-terminal domain has been disrupted are more sensitive to chemical ablation than wild-type GLUT4. These data indicate that GLUT4 contains a targeting signal in its C-terminus, distal to the dileucine motif, that regulates its sorting into a post-endosomal compartment. Similar membrane-distal, acidic-cluster-based motifs are found in the cytosolic tails of the insulin-responsive aminopeptidase IRAP (insulin-regulated aminopeptidase) and the proprotein convertase PC6B, indicating that this type of motif may play an important role in the endosomal sequestration of a number of different proteins.
