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

Phosphorylation of inositol phospholipids plays a key role in cellular regulation via the generation of intracellular second messengers. In addition, it represents a mechanism to regulate interactions of the lipid bilayer with proteins and protein scaffolds involved in vesicle budding, cytoskeletal organization, and signaling. Generation of phosphatidylinositol 4-phosphate [PI(4)P] from phosphatidylinositol (PI) is an important step in this metabolic pathway because PI(4)P is a precursor of other important phosphoinositides and has protein binding properties of its own. We report here that a PI 4-kinase (PI4K) activity previously reported on synaptic vesicles is accounted for by the alpha isoform of the recently characterized type II PI4K (PI4KII) family. PI4KIIalpha, which also accounts for the bulk of PI4K activity in brain extracts, is concentrated at synapses and in the region of the Golgi complex in neuronal perikarya. Our results provide new evidence for the occurrence of a cycle of phosphoinositide synthesis and hydrolysis nested within the exo-endocytic cycle of synaptic vesicles and point to PI4KIIalpha as a critical player in this cycle.
