Clathrin and clathrin-accessory proteins in rat kidney cortex epithelia.
Article in Histochemistry and cell biology, 2006. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Several vectorial transport routes in mammalian cells involve clathrin and associated proteins. In kidney epithelia urine production requires numerous transport processes. However, only little is known about the distribution of clathrin and its associated proteins in this organ in situ. We now report on the presence and distribution of clathrin and its accessory proteins AP1, AP2, Eps15, Epsin, CALM and Clint/EpsinR in the epithelia of the rat kidney cortex using immunoblotting, immunofluorescence and immuno-electron microscopy. Our data show that all investigated proteins are ubiquitously present in rat kidney cortex epithelia, however, with distinct distribution patterns. In the renal corpuscle, podocytes showed the most conspicuous labelling. Clathrin, AP2 and CALM were highly expressed in foot processes, while AP1 was primarily localized in the cell body. In the proximal tubule all proteins were present in dots along the plasma membrane and most conspicuous below the brush border. However, clathrin and AP2 co-localized in vesicle subtypes distinct from those containing clathrin and AP1. In the distal tubule and in the cortical collecting duct all proteins were found in the apex of the cells; however, AP1 and Clint/EpsinR showed additional staining in perinuclear dots. The occurrence and distribution of the investigated proteins in kidney epithelia are discussed with respect to their possible involvement in the functions of the specific nephron segment.
