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

Pericytes regulate microvascular development and maturation through the control of endothelial cell motility, proliferation, and differentiation. The Rho GTPases have recently been described as key regulators of pericyte shape and contractile phenotype by signaling through the actin cytoskeleton in an isoactin-specific manner. In this report, we reveal that Rho GTPase-dependent signal transduction not only influences pericyte shape and contractile potential but also modulates capillary endothelial proliferative status and pericyte-endothelial interactions in vitro. We provide evidence that overexpression of mutant Rho GTPases, but not other Ras-related small GTPases, significantly alters pericyte shape, contractility, and endothelial growth state in microvascular cell co-cultures. In particular, we describe the use of a silicon substrate deformation assay to demonstrate that pericyte contractility is Rho GTP- and Rho kinase-dependent; further, we describe a novel in vitro system for examining pericyte-mediated endothelial growth arrest and show that control pericytes are capable of growth-arresting capillary endothelial cells in a cell contact-dependent manner, whereas pericytes overexpressing dominant-active and -negative Rho GTPase are comparably incompetent. These data strongly suggest that signaling through the pericyte Rho GTPase pathway may provide critical cues to the processes of microvascular stabilization, maturation, and contractility during development and disease.
