Differential Regulation of Glucosylceramide Synthesis and Efflux by Golgi and Plasma Membrane Bound ABCC10.
Article in Nutrients, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Glucosylceramide (GlcCer) synthesis by the enzyme glucosylceramide synthase (GCS) occurs on the cytosolic leaflet of the Golgi and is the first important step for the synthesis of complex glycosphingolipids (GSLs) that takes place inside the lumen. Apart from serving as a precursor for glycosylation, newly synthesized GlcCer is also transported to the plasma membrane and secreted onto HDL in the circulation. The mechanism by which GlcCer is transported to HDL remains unclear. Recently, we showed that ATP-binding cassette transporter protein C10 (ABCC10) plays an important role in the synthesis and efflux of GlcCer in Huh-7 cells. In this study, we found that treatment of Huh-7 cells with an ABCC10 inhibitor, sorafenib, decreased the synthesis and efflux of GlcCer. However, treatment of cells with cepharanthine reduced only the efflux, but not synthesis, of GlcCer. These results indicate that ABCC10 may regulate the synthesis and efflux of GlcCer differentially in liver cells.
