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

Intravascular pressure-induced vasoconstriction is a smooth muscle cell-specific mechanism that controls systemic blood pressure and organ regional blood flow. Smooth muscle cell polycystin-1 and -2 (TRPP1 and -2) proteins modulate the myogenic response in mesenteric arteries, but involvement in other vascular beds is unclear. Here, we examined TRPP2 expression, cellular distribution, cation currents (ICat), and physiological functions in smooth muscle cells of rat and human cerebral arteries. We demonstrate that TRPP2 is the major TRPP isoform expressed in cerebral artery smooth muscle cells, with message levels higher than those of TRPP1. Arterial biotinylation and immunofluorescence indicated that TRPP2 is located primarily (∼88%) in the smooth muscle cell plasma membrane. RNA interference reduced TRPP2 expression by ∼55% compared to control, but did not alter levels of TRPP1, TRPC1, TRPC3, TRPC6, TRPM4, ANO1/TMEM16A, or voltage-dependent Ca(2+) (CaV1.2) channels, other ion channel proteins that modulate myogenic tone. Cell swelling induced by hyposmotic (250 osmol (l solution)(-1)) bath solution stimulated Gd(3+)-sensitive ICat in smooth muscle cells that were reduced by selective TRPP2 knockdown. TRPP2 knockdown did not alter myogenic tone at 20 mmHg but reduced tone between ∼28 and 39% over an intravascular pressure range between 40 and 100 mmHg. In contrast, TRPP2 knockdown did not alter depolarization-induced (60 mmol l K(+)) vasoconstriction. In summary, we show that TRPP2 is expressed in smooth muscle cells of resistance-size cerebral arteries, resides primarily in the plasma membrane, and contributes to the myogenic response. Data also suggest that TRPP2 differentially regulates the myogenic response in cerebral and mesenteric arteries.
