Docosahexaenoic acid inhibits protein kinase C translocation/activation and cardiac hypertrophy in rat cardiomyocytes.
Article in Journal of molecular and genetic medicine : an international journal of biomedical research, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Phenylephrine (PE) induces cardiac hypertrophy through multiple signaling pathways including pathways involving protein kinase C (PKC) activation. Docosahexaenoic acid (DHA), an omega-3 fatty acid, has been shown to reduce the PE-induced hypertrophic responses. However, the effects of DHA on PKC activation and translocation are controversial. The present study investigates the effect of DHA on PE-induced activation of PKC. The results indicate that PE induces PKCalpha translocation (from cytosol to plasma membranes) and activation in cardiomyocytes during the hypertrophic responses. Although DHA itself has no significant effect on basal PKC translocation and activation, it effectively reduced PE-stimulated PKC translocation and activation. The results of the present study suggest a possible mechanism explaining how dietary fish oil may inhibit development of cardiac hypertrophy and therefore may be an attractive dietary agent for preventing cardiac hypertrophy in patients with heart failure.
