Vacuolar H(+)-ATPase of adrenal secretory granules. Rapid partial purification and reconstitution into proteoliposomes.
Article in The Biochemical journal, 1990. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 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
A procedure has been developed for the rapid purification and reconstitution into phospholipid vesicles of the proton-translocating ATPase of bovine adrenal chromaffin-granule membranes. It involves fractionation of the membranes with Triton X-114, resolubilization of the ATPase with n-octyl glucoside, addition of purified lipids and removal of detergent by gel filtration. The entire process can be completed within 2 h. H+ translocation was detected by the ATP-dependent quenching of the fluorescence of a permeant weak base. The effect of varying the lipid composition of the vesicles on ATP hydrolysis and H+ translocation by the reconstituted enzyme was examined. ATPase activity was maximally increased about 4-fold by added lipid, but was relatively insensitive to its composition, whereas vesicle acidification was absolutely dependent on the addition of phospholipids and cholesterol.
