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 small RNAs that fulfill diverse functions by negatively regulating gene expression. Here, we investigated the involvement of miRNAs in the chondrogenic differentiation of chick limb mesenchymal cells and found that the expression of miR-221 increased upon chondrogenic inhibition. Blockade of miR-221 via peanut agglutinin-based antisense oligonucleotides reversed the chondro-inhibitory actions of a JNK inhibitor on the proliferation and migration of chondrogenic progenitors as well as the formation of precartilage condensations. We determined that mdm2 is a relevant target of miR-221 during chondrogenesis. miR-221 was necessary and sufficient to down-regulate Mdm2 expression, and this down-modulation of Mdm2 by miR-221 prevented the degradation of (and consequently up-regulated) the Slug protein, which negatively regulates the proliferation of chondroprogenitors. These results indicate that miR-221 contributes to the regulation of cell proliferation by negatively regulating Mdm2 and thereby inhibiting Slug degradation during the chondrogenesis of chick limb mesenchymal cells.
