A role for fascin in preventing filopodia breakage in Drosophila tracheal cells.
Article in Communicative & integrative biology, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Filopodia are long and thin finger-like protrusions essential for cell migration. They are formed by parallel actin bundles tightly packed by cell type and context dependent actin-bundling proteins. Our recent work analyzing the role of Fascin during tracheal development in Drosophila has shown that Singed (the Drosophila Fascin homolog) acts as a molecular link between the Branchless (FGF)/Breathless (FGFR) pathway and the actin cytoskeleton. We have reported that the lack of Singed (Sn) leads to wavy and flaccid filopodia due to the disorganization of the tracheal actin cytoskeleton. Here we describe for the first time filopodia breakage in Drosophila, and show that Fascin plays a role in this event. We propose that actin filaments in sn mutant filopodia buckle under membrane pressure due to lower bending stiffness, eventually undergoing breakage. Both Filopodia buckling and breakage would impair correct cell navigation and migration.
