Convergent, RIC-8-dependent Galpha signaling pathways in the Caenorhabditis elegans synaptic signaling network.
Article in Genetics, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 55 papers.
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
We used gain-of-function and null synaptic signaling network mutants to investigate the relationship of the G alpha(q) and G alpha(s) pathways to synaptic vesicle priming and to each other. Genetic epistasis studies using G alpha(q) gain-of-function and null mutations, along with a mutation that blocks synaptic vesicle priming and the synaptic vesicle priming stimulator phorbol ester, suggest that the G alpha(q) pathway generates the core, obligatory signals for synaptic vesicle priming. In contrast, the G alpha(s) pathway is not required for the core priming function, because steady-state levels of neurotransmitter release are not significantly altered in animals lacking a neuronal G alpha(s) pathway, even though these animals are strongly paralyzed as a result of functional (nondevelopmental) defects. However, our genetic analysis indicates that these two functionally distinct pathways converge and that they do so downstream of DAG production. Further linking the two pathways, our epistasis analysis of a ric-8 null mutant suggests that RIC-8 (a receptor-independent G alpha guanine nucleotide exchange factor) is required to maintain both the G alpha(q) vesicle priming pathway and the neuronal G alpha(s) pathway in a functional state. We propose that the neuronal G alpha(s) pathway transduces critical positional information onto the core G alpha(q) pathway to stabilize the priming of selected synapses that are optimal for locomotion.
