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

Ca(2+) signals regulate polarization, speed, and turning of migrating cells. However, the molecular mechanism by which Ca(2+) acts on moving cells is not understood. Here we show that local Ca(2+) pulses along the front of migrating human endothelial cells trigger cycles of retraction of local lamellipodia and, concomitantly, strengthen local adhesion to the extracellular matrix. These Ca(2+) release pulses had small amplitudes and diameters and were triggered repetitively near the leading plasma membrane with only little coordination between different regions. We show that each Ca(2+) pulse triggers contraction of actin filaments by activating myosin light-chain kinase and myosin II behind the leading edge. The cyclic force generated by myosin II operates locally, causing a partial retraction of the nearby protruding lamellipodia membrane and a strengthening of paxillin-based focal adhesion within the same lamellipodia. Photo release of Ca(2+) demonstrated a direct role of Ca(2+) in triggering local retraction and adhesion. Together, our study suggests that spatial sensing, forward movement, turning, and chemotaxis are in part controlled by confined Ca(2+) pulses that promote local lamellipodia retraction and adhesion cycles along the leading edge of moving cells.
