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

Mitochondrial structure and function are central to cell physiology and are mutually interdependent. Mitochondria represent a primary target of the alcohol-induced tissue injury, particularly in the liver, where the metabolic effects of ethanol are predominant. However, the effect of ethanol on hepatic mitochondrial morphology and dynamics remain to be established. In the present work, we employed the organelle-targeted photoactivatable fluorescent protein technology and electron microscopy to study hepatic mitochondrial structure and dynamics. Hepatocytes in perfused liver as well as in primary cultures showed mostly discrete globular or short tubular mitochondria. The mitochondria showed few fusion events and little movement activity. By contrast, human hepatoma (HepG2)-derived VL-17A cells, expressing the major hepatic ethanol metabolizing enzymes, alcohol dehydrogenase and cytochrome P450 2E1, have elongated and interconnected mitochondria showing matrix continuity and many fusion events. Hepatocytes isolated from chronically ethanol-fed rats showed some increase in mitochondrial volume and exhibited a substantial suppression of mitochondrial dynamics. In VL-17A cells, prolonged ethanol exposure also caused decreased mitochondrial continuity and dynamics. Collectively, these results indicate that mitochondria in normal hepatocytes show relatively slow dynamics, which is very sensitive to suppression by ethanol exposure.
