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

Establishment and maintenance of a polar distribution of Na+,K(+)-ATPase is essential for efficient Na+ reabsorption by proximal tubule cells and is dependent upon the formation of a metabolically stable, detergent-insoluble complex of Na+,K(+)-ATPase with the actin membrane cytoskeleton. The present studies show that cellular ATP depletion results in a rapid duration-dependent dissociation of Na+,K(+)-ATPase from the actin cytoskeleton and redistribution of Na+,K(+)-ATPase to the apical membrane. During ATP depletion, total cellular Na+,K(+)-ATPase activity was unaltered, but the Triton-X-100-insoluble fraction (cytoskeleton associated) of Na+,K(+)-ATPase activity decreased (P less than 0.01), with a corresponding increase in the detergent-soluble fraction of Na+,K(+)-ATPase (P less than 0.01). Indirect immunofluorescent studies of cells with depleted ATP revealed a redistribution of Na+,K(+)-ATPase from the basolateral membrane into the apical membrane and throughout the cytoplasm. ATP depletion also resulted in the redistribution of F-actin from a primarily cortical concentration to a perinuclear location. There was also a rapid, duration-dependent conversion of monomeric G-actin to F-actin starting during the first 5 min of ATP depletion. Taken together, these data suggest that ATP depletion causes profound alterations in cell polarity by inducing major changes in the actin cytoskeletal architecture.
