1 · What the graph read from it

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.

2 · The registry

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

backgroundBreastfeeding is the ideal source of infant nutrition. Human milk consists not only of nutrients but also biologically active components. Among these latter compounds, exosomes contain proteins, lipids, mRNAs and miRNAs.

methodsTo elucidate the biological effects of milk-derived exosomes (MDEs) on normal colonic epithelial cells compared to colonic tumor cells, we incubated cells with MDEs. MDEs were able to enter into normal and tumor cells and change their miRNA expression profiles. Proliferation, cell morphology and protein expression were analyzed in these cells.

resultsHuman milk-derived exosomes induced proliferation- and epithelial mesenchymal transformation-related changes, such as collagen type I and twist expression, in normal but not in tumor cells. PTEN, a target of miRNA-148a, was downregulated in normal but not in tumor cells following incubation with MDEs. Moreover, miRNA-148a-3p knockdown cells were used to demonstrate the importance of miRNA in the effect of exosomes on cell proliferation and protein expression. MDEs inhibited proliferation and DNMT1 expression in cells with knockdown of miRNA-148a.

conclusionsIn conclusion, the positive effect of exosomes on normal cells without affecting tumor cells may presents an aspect of their safety when considering it use as a nutritional supplement to infant formula.
