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

Alpha-neurexins constitute a family of neuronal cell surface molecules that are essential for efficient neurotransmission, because mice lacking two or all three alpha-neurexin genes show a severe reduction of synaptic release. Although analyses of alpha-neurexin knock-outs and transgenic rescue animals suggested an involvement of voltage-dependent Ca2+ channels, it remained unclear whether alpha-neurexins have a general role in Ca2+-dependent exocytosis and how they may affect Ca2+ channels. Here we show by membrane capacitance measurements from melanotrophs in acute pituitary gland slices that release from endocrine cells is diminished by >50% in adult alpha-neurexin double knock-out and newborn triple knock-out mice. There is a reduction of the cell volume in mutant melanotrophs; however, no ultrastructural changes in size or intracellular distribution of the secretory granules were observed. Recordings of Ca2+ currents from melanotrophs, transfected human embryonic kidney cells, and brainstem neurons reveal that alpha-neurexins do not affect the activation or inactivation properties of Ca2+ channels directly but may be responsible for coupling them to release-ready vesicles and metabotropic receptors. Our data support a general and essential role for alpha-neurexins in Ca2+-triggered exocytosis that is similarly important for secretion from neurons and endocrine cells.
