Intracellular pH sensing is altered by plasma membrane PIP aquaporin co-expression.

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
The plant plasma membrane barrier can express aquaporins (PIP1 and PIP2) that show two intriguing aspects: (1) the potential of modulating whole membrane water permeability by co-expression of both types, which have recently been distinguished for showing a different capacity to reach the plasma membrane; and (2) the faculty to reduce water permeation through the pore after cytosolic acidification, as a consequence of a gating process. Our working hypothesis is that these two key features might enhance plasticity of the membrane water transport capacity if they jointly trigger any cooperative interaction. In previous work, we proved by biophysical approaches that the plasma membrane of the halophyte Beta vulgaris storage root presents highly permeable aquaporins that can be shut down by acidic pH. Root Beta vulgaris PIPs were therefore subcloned and expressed in Xenopus oocytes. Co-expression of BvPIP1;1 and BvPIP2;2 not only enhances oocyte plasma membrane water permeability synergistically but also reinforces pH inhibitory response from partial to complete shut down after cytosolic pH acidification. This pH dependent behavior shows that PIP1-PIP2 co-expression accounts for a different pH sensitivity in comparison with PIP2 expression. These results prove for the first time that PIP co-expression modulates the membrane water permeability through a pH regulatory response, enhancing in this way membrane versatility to adjust its water transfer capacity.
