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

Processing of primary microRNA (pri-miRNA) stem-loops by the Drosha-DGCR8 complex is the initial step in miRNA maturation and crucial for miRNA function. Nonetheless, the underlying mechanism that determines the Drosha cleavage site of pri-miRNAs has remained unclear. Two prevalent but seemingly conflicting models propose that Drosha-DGCR8 anchors to and directs cleavage a fixed distance from either the basal single-stranded (ssRNA) or the terminal loop. However, recent studies suggest that the basal ssRNA and/or the terminal loop may influence the Drosha cleavage site dependent upon the sequence/structure of individual pri-miRNAs. Here, using a panel of closely related pri-miRNA variants, we further examine the role of pri-miRNA structures on Drosha cleavage site selection in cells. Our data reveal that both the basal ssRNA and terminal loop influence the Drosha cleavage site within three pri-miRNAs, the Simian Virus 40 (SV40) pri-miRNA, pri-miR-30a, and pri-miR-16. In addition to the flanking ssRNA regions, we show that an internal loop within the SV40 pri-miRNA stem strongly influences Drosha cleavage position and efficiency. We further demonstrate that the positions of the internal loop, basal ssRNA, and the terminal loop of the SV40 pri-miRNA cooperatively coordinate Drosha cleavage position and efficiency. Based on these observations, we propose that the pri-miRNA stem, defined by internal and flanking structural elements, guides the binding position of Drosha-DGCR8, which consequently determines the cleavage site. This study provides mechanistic insight into pri-miRNA processing in cells that has numerous biological implications and will assist in refining Drosha-dependent shRNA design.
