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

We have recently shown that calmodulin antagonist W13 interferes with the trafficking of the epidermal growth factor receptor (EGFR) and regulates the mitogen-activated protein kinase (MAPK) signaling pathway. In the present study, we demonstrate that in cells in which calmodulin is inhibited, protein kinase C (PKC) inhibitors rapidly restore EGFR and transferrin trafficking through the recycling compartment, although onward transport to the degradative pathway remains arrested. Analysis of PKC isoforms reveals that inhibition of PKCdelta with rottlerin or its down-modulation by using small interfering RNA is specifically responsible for the release of the W13 blockage of EGFR trafficking from early endosomes. The use of the inhibitor Gö 6976, specific for conventional PKCs (alpha, beta, and gamma), or expression of dominant-negative forms of PKClambda, zeta, or epsilon did not restore the effects of W13. Furthermore, in cells treated with W13 and rottlerin, we observed a recovery of brefeldin A tubulation, as well as transport of dextran-fluorescein isothiocyanate toward the late endocytic compartment. These results demonstrate a specific interplay between calmodulin and PKCdelta in the regulation of the morphology of and trafficking from the early endocytic compartment.
