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

MicroRNAs (miRNAs) are critical regulators of gene expression, and exert extensive impacts on development, physiology, and disease of eukaryotes. A high degree of parallelism is found in the molecular basis of miRNA biogenesis and action in plants and animals. Recent studies interestingly suggest a potential cross-kingdom action of plant-derived miRNAs, through dietary intake, in regulating mammalian gene expression. Although the source and scope of plant miRNAs detected in mammalian specimens remain controversial, these initial studies inspired us to determine whether plant miRNAs can be detected in Western human sera and whether these plant miRNAs are able to influence gene expression and cellular processes related to human diseases such as cancer. Here we found that Western donor sera contained the plant miRNA miR159, whose abundance in the serum was inversely correlated with breast cancer incidence and progression in patients. In human sera, miR159 was predominantly detected in the extracellular vesicles, and was resistant to sodium periodate oxidation suggesting the plant-originated 2'-O-methylation on the 3' terminal ribose. In breast cancer cells but not non-cancerous mammary epithelial cells, a synthetic mimic of miR159 was capable of inhibiting proliferation by targeting TCF7 that encodes a Wnt signaling transcription factor, leading to a decrease in MYC protein levels. Oral administration of miR159 mimic significantly suppressed the growth of xenograft breast tumors in mice. These results demonstrate for the first time that a plant miRNA can inhibit cancer growth in mammals.
