Dual effect of docosahexaenoic acid (attenuation or amplification) on C22:0-, C24:0-, and C26:0-induced mitochondrial dysfunctions and oxidative stress on human neuronal SK-N-BE cells.

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
Increased levels of C22:0, C24:0 and C26:0 were found in cortical lesions of patients with Alzheimer's disease (AD). So, it was of interest to precise the cytotoxic effects of these fatty acids, and to determine whether docosahexaenoic acid (DHA), described to prevent AD, can attenuate their eventual side effects. Human neuronal SK-N-BE cells were cultured in the absence or presence of C22:0, C24:0 or C26:0 (0.1-20 µM) without or with DHA (50-150 µM). C22:0, C24:0 and C26:0 induce an inhibition of cell growth, a loss of Δψm, an overproduction of reactive oxygen species (ROS), a decrease of reduced glutathione, and a lipid peroxidation. DHA attenuates C22:0, C24:0 and C26:0 induced-mitochondrial dysfunctions and/or cell growth inhibition measured with MTT whatever the concentrations considered, whereas it can either decrease or amplify (especially at 150 µM) ROS overproduction. C22:0, C24:0 and C26:0 have neurotoxic activities, and depending on its concentration, DHA attenuates or not fatty acid-induced side effects.
