The vacuolar-type H-ATPase in ovine rumen epithelium is regulated by metabolic signals.
Article in Journal of biomedicine & biotechnology, 2010. 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
In this study, the effect of metabolic inhibition (MI) by glucose substitution with 2-deoxyglucose (2-DOG) and/or application of antimycin A on ovine rumen epithelial cells (REC) vacuolar-type H(+)-ATPase (vH(+)-ATPase) activity was investigated. Using fluorescent spectroscopy, basal pH(i) of REC was measured to be 7.3 +/- 0.1 in HCO(3) (-)-free, glucose-containing NaCl medium. MI induced a strong pH(i) reduction (-0.44 +/- 0.04 pH units) with a more pronounced effect of 2-DOG compared to antimycin A (-0.30 +/- 0.03 versus -0.21 +/- 0.03 pH units). Treatment with foliomycin, a specific vH(+)-ATPase inhibitor, decreased REC pH(i) by 0.21 +/- 0.05 pH units. After MI induction, this effect was nearly abolished (-0.03 +/- 0.02 pH units). In addition, membrane-associated localization of vH(+)-ATPase B subunit disappeared. Metabolic control of vH(+)-ATPase involving regulation of its assembly state by elements of the glycolytic pathway could provide a means to adapt REC ATP consumption according to energy availability.
