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

In recent years, RNA interference (RNAi) has emerged as an effective method to target specific genes for silencing. Several groups are actively exploring the use of small interfering RNA (siRNA) for therapeutic applications to treat cancer. Our previous studies have demonstrated the inhibition of various proteases, including serine proteases, cysteine proteases and matrix metalloproteases, via RNA interference (RNAi) in gliomas. Similar to gliomas, malignant meningiomas also exhibit elevated protease levels in comparison to normal brain and benign meningiomas. Here, we used siRNA to simultaneously target urokinase plasminogen activator (uPA) and its receptor, uPAR. A human CMV promoter-driven mammalian expression vector (pU2) was used to produce hairpin double-stranded RNA (hp RNA) to target uPA and uPAR. As determined by Western blotting and fibrin zymography, pU2 effectively inhibited uPAR protein levels and uPA enzymatic activity in meningioma cells (IOMM-Lee). In vitro studies (Matrigel invasion and spheroid migration) revealed reduced meningioma cell invasion and migration. Intratumoral injections of the plasmid vector expressing siRNA for uPA and uPAR resulted in regression of pre-established, subcutaneous tumors in mice. In addition, in vivo studies of mice injected with pU2-transfected meningioma cells revealed inhibition of intracranial tumor formation. These findings suggest that siRNA can be used as a potent and specific therapeutic tool for the treatment of malignant meningiomas in humans.
