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

The nonselective cation channel transient receptor potential canonical (TRPC)5 is found predominantly in the brain and has been proposed to regulate neuronal processes and growth cones. Here, we demonstrate that semaphorin 3A-mediated growth cone collapse is reduced in hippocampal neurons from TRPC5 null mice. This reduction is reproduced by inhibition of the calcium-sensitive protease calpain in wild-type neurons but not in TRPC5(-/-) neurons. We show that calpain-1 and calpain-2 cleave and functionally activate TRPC5. Mutation of a critical threonine at position 857 inhibits calpain-2 cleavage of the channel. Finally, we show that the truncated TRPC5 predicted to result from calpain cleavage is functionally active. These results indicate that semaphorin 3A initiates growth cone collapse via activation of calpain that in turn potentiates TRPC5 activity. Thus, TRPC5 acts downstream of semaphorin signaling to cause changes in neuronal growth cone morphology and nervous system development.
