Trans-membrane uptake and intracellular metabolism of fatty acids in Atlantic salmon (Salmo salar L.) hepatocytes.
Article in Lipids, 2010. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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.
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
To elucidate if the trans-membrane uptake of fatty acids is protein-mediated, the uptake of oleic acid (18:1n-9), linoleic acid (18:2n-6), alpha-linolenic acid (18:3n-3), eicosapentaenoic acid (20:5n-3) and docosahexaenoic acid (22:6n-3) was investigated in vitro in Atlantic salmon (Salmo salar L.) primary hepatocytes. Firstly, optimal fatty acid incubation time and concentration were established for trans-membrane 18:n-9 uptake. Based on saturation kinetics, a 2-h incubation time and 37.5 muM were used for the following experiments. Secondly, in order to identify whether trans-membrane fatty acid uptake in hepatocytes was mainly passive or protein mediated, hepatocytes were pre-incubated with membrane protein inhibitors followed by 2 h of incubation with [1-(14)C] labelled 18:1n-9, 18:2n-6, 18:3n-3, 20:5n-3 and 22:6n-3. Fatty acid uptake into hepatocytes was highest with 20:5n-3 and 22:6n-3 and lowest with 18:1n-9. Phloretin was the most potent fatty acid uptake inhibitor, inhibiting uptake in the following order: 20:5n-3 > 18:3n-3 = 22:6n-3 > 18:2n-6 > 18:1n-9. The uptake of FA in Atlantic salmon hepatocytes seem to be due to both saturable and inhibitable protein mediated uptake, as well as passive uptake processes with more unsaturated and long fatty acids (20:n-3 > 22:6n-3 = 18:3n-3 > 18:2n-6) being more dependent on membrane protein mediated uptake compared to 18:1n-9.
