Phellinus linteus polysaccharide extracts increase the mitochondrial membrane potential and cause apoptotic death of THP-1 monocytes.

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
backgroundThe differentiation resp. death of human monocytic THP-1 cells induced by polysaccharide extracts of the medicinal mushrooms Phellinus linteus, Agaricus bisporus and Agaricus brasiliensis have been studied. This study aims to identify leads for the causal effects of these mushroom components on cell differentiation and death.
methodsTHP-1 cells were treated with different polysaccharide extracts of mushrooms and controls. Morphological effects were observed by light microscopy. Flow cytometry was applied to follow the cell differentiation by cell cycle shifts after staining with propidium iodide, changes of mitochondrial membrane potential after incubation with JC-1, and occurrence of intracellular reactive oxygen species after incubation with hydroethidine. Principal component analysis of the data was performed to evaluate the cellular effects of the different treatments.
resultsP. linteus polysaccharide extracts induced dose-dependent apoptosis of THP-1 cells within 24 h, while A. bisporus and A. brasiliensis polysaccharide extracts caused differentiation into macrophages. A pure P. linteus polysaccharide had no effect. Apoptosis was inhibited by preincubating THP-1 cells with human serum. The principal component analysis revealed that P. linteus, A. bisporus and A. brasiliensis polysaccharide extracts increased reactive oxygen species production. Both A. bisporus and A. brasiliensis polysaccharide extracts decreased the mitochondrial membrane potential, while this was increased by P. linteus polysaccharide extracts.
conclusionsP. linteus polysaccharide extracts caused apoptosis of THP-1 monocytes while A. bisporus and A. brasiliensis polysaccharide extracts caused these cells to differentiate into macrophages. The protective effects of human serum suggested that P. linteus polysaccharide extract induced apoptosis by extrinsic pathway, i.e. by binding to the TRAIL receptor. The mitochondrial membrane potential together with reactive oxygen species seems to play an important role in cell differentiation and cell death.
