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

Disorganization of the cytoskeleton of neurons has major consequences on the transport of neurotransmitters via the microtubule network. The interaction of cytoskeleton proteins (actin and tubulin) was studied in neuronal SK-N-BE cells treated with tetracosanoic acid (C24:0), which is cytotoxic and increased in Alzheimer's disease patients. When SK-N-BE cells were treated with C24:0, mitochondrial dysfunctions and a non-apoptotic mode of cell death were observed. Fluorescence microscopy revealed shrunken cells with perinuclear condensation of actin and tubulin. Impact of C24:0 on actin-microtubule interaction in human neuronal SK-N-BE cells: evaluation by FRET confocal spectral imaging microscopy after dual staining with rhodamine-phalloidin and tubulin tracker green After staining with rhodamine-phalloidin and with an antibody raised against α-/β-tubulin, modifications of F-actin and α-/β-tubulin levels were detected by flow cytometry. Lower levels of α-tubulin were found by Western blotting. In C24:0-treated cells, spectral analysis and fluorescence recovery after photobleaching (FRAP) measured by confocal microscopy proved the existence of fluorescence resonance energy transfer (FRET) when actin and tubulin were stained with tubulin tracker and rhodamine-phalloidin demonstrating actin and tubulin co-localization/interaction. In control cells, no FRET was observed. Our data demonstrate quantitative changes in actin and tubulin, and modified interactions between actin and tubulin in SK-N-BE cells treated with C24:0. They also show that FRET confocal imaging microscopy is an interesting method for specifying the impact of cytotoxic compounds on cytoskeleton proteins.
