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

backgroundMicroRNAs (miRNAs) are small noncoding RNAs that regulate the expression of approximately 60% of all human genes. They play important roles in numerous cellular processes, including development, proliferation, and apoptosis. Currently, it is believed that miRNAs elicit their effect by silencing the expression of target genes. In this study, the authors demonstrated that miRNA-205 (miR-205) induced the expression the interleukin (IL) tumor suppressor genes IL24 and IL32 by targeting specific sites in their promoters.

methodsThe methods used in this study included transfection of small RNAs; quantitative real-time polymerase chain reaction; in situ hybridization; fluorescence-labeled in situ hybridization; cell cycle, apoptosis, cell viability, migratory, clonability, and invasion assays; immunoblotting; and luciferase reporter, nuclear run-on, and chromatin immunoprecipitation assays.

resultsThe results revealed that miR-205 was silenced in prostate cancer. Its re-expression induced apoptosis and cell cycle arrest. It also impaired cell growth, migration, clonability, and invasiveness of prostate cancer cells. Micro-RNA-205 induced the expression of tumor suppressor genes IL24 and IL32 at both the messenger RNA and protein levels. The induction of in vitro transcription and enrichment of markers for transcriptionally active promoters in the IL24 and IL32 genes was observed in response to miR-205.

conclusionsIn this study, a new function for miR-205 was identified that specifically activated tumor suppressor genes by targeting specific sites in their promoters. These results corroborate a newly identified function that miRNAs have in regulating gene expression at the transcriptional level. The specific activation of tumor suppressor genes (eg, IL24, IL32) or other dysregulated genes by miRNA may contribute to a novel therapeutic approach for the treatment of prostate cancer.
