Low p21 level is necessary for the suppressive effects of micoRNA-31 on glioma cell migration and invasion.
Article in Tumour biology : the journal of the International Society for Oncodevelopmental Biology and Medicine, 2016. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Not yet cited in PubMed.
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.
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), a kind of endogenous non-coding RNAs, regulate gene expression through binding to the 3'-untranslational region (UTR) of target messenger RNAs (mRNAs) and act as endogenous agents of RNA interference, resulting in either mRNA degradation or translational repression. MiR-31 has been demonstrated to be associated with the development and progression of glioma. However, the underlying molecular mechanism remains largely unclear. In the present study, we demonstrated that miR-31 only inhibited the cell migration and invasion, as well as the expression of a known miR-31 target oncogene radixin, in U251 glioma cells that expressed low level of p21; however, miR-31 showed no above effects on glioma SHG44 cells that highly expressed p21. Moreover, upregulation of p21 in U251 cells reversed the suppressive effects of miR-31 on the cell migration and invasion, suggesting that low p21 level is necessary for the miR-31-mediated inhibitory effects on glioma. Furthermore, analysis for 35 glioma specimens showed that the expression of radixin was negatively correlated with the miR-31 level in glioma tissues with low p21 expression; however, no such correlation was found in glioma tissues with high p21 level, further supporting that the low p21 level is necessary for the suppressive effect of miR-31 on the expression of its target oncogenes. In summary, our study demonstrates that the suppressive effect of miR-31 on glioma cell migration and invasion is p21-dependent, and suggests that miR-31 may be used for the treatment of patients with p21-deficent glioma.
