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

1. Receptor-mediated endocytosis in epithelial cells is a crucial mechanism for transport of macromolecules and regulation of cell-surface protein expression. Na+-H+ exchanger type 3 (NHE3) has been shown to cycle between the apical plasma membrane and the early endosomal compartment and to interfere with endocytosis. 2. In the present study we investigated in detail the NHE3-dependent step of apical endocytosis in an epithelial cell line (opossum kidney cells). 3. Inhibition of NHE3 led to a rapid dose-dependent inhibition of apical albumin endocytosis but did not affect basolateral transferrin endocytosis. Re-exocytosis of albumin was not increased by NHE3 inhibition. 4. NHE3 dependency of albumin endocytosis was still observed at 20 degrees C or when microtubules had been disrupted. This was not the case for inhibition of vacuolar H+-ATPase. 5. NHE3 inhibition rapidly blocked internalisation of pre-bound albumin and attenuated degradation of internalised albumin without changing general protein degradation. 6. Furthermore, NHE3 inhibition reduced the rate of endocytic vesicle fusion significantly. 7. In summary, our data indicate that NHE3 is important for the early phase of the apical endocytic pathway, located between the plasma membrane and early endosomes, at least in part due to its involvement in endocytic vesicle fusion.
