Retinoid-induced mu opioid receptor expression by phytohemagglutinin-stimulated U937 cells.
Article in Journal of neurovirology, 2005. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Opioid use may be associated with an increased risk of neurological disease in human immunodeficiency virus (HIV) infection through effects on immune cell function. Studies were performed to examine the effects of specific retinoid receptor activation on mu opioid receptor (MOR) production by phytohemagglutinin (PHA)-stimulated U937 cells, a mononuclear cell line. PHA stimulation increased activation of the MOR promoter as well as levels of MOR mRNA, total receptor protein in cell lysates, and surface and cytoplasmic receptor expression. Retinoid X receptor (RXR) agonist and retinoic acid receptor (RAR) antagonist further increased MOR expression by the PHA-stimulated cells. In contrast, MOR expression was suppressed by RAR agonist and by RXR antagonist. Finally, opioid receptor binding was also increased by RXR agonist and RXR antagonist; no increase in binding occurred in the presence of RAR agonists and RXR antagonist. All together, these studies suggest that MOR expression in U937 cells can be differentially regulated by specific retinoid receptor activation. Such effects may have important clinical relevance for opioid users with HIV infection, including individuals with neurological disease.
