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

Intracellular transport regulates protein turnover including endocytosis. Because of the spatial segregation of F-actin and microtubules, internalized cargo vesicles need to employ myosin and dynein motors to traverse both cytoskeletal compartments. Factors specifying cargo delivery across both tracks remain unknown. We identified muskelin to interconnect retrograde F-actin- and microtubule-dependent GABA(A) receptor (GABA(A)R) trafficking. GABA(A)Rs regulate synaptic transmission, plasticity, and network oscillations. GABA(A)R α1 and muskelin interact directly, undergo neuronal cotransport, and associate with myosin VI or dynein motor complexes in subsequent steps of GABA(A)R endocytosis. Inhibition of either transport route selectively interferes with receptor internalization or degradation. Newly generated muskelin KO mice display depletion of both transport steps and a high-frequency ripple oscillation phenotype. A diluted coat color of muskelin KOs further suggests muskelin transport functions beyond neurons. Our data suggest the concept that specific trafficking factors help cargoes to traverse both F-actin and microtubule compartments, thereby regulating their fate.
