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

Long-lasting siRNA-based down-regulation of gene of interest can be achieved by lentiviral-based expression vectors driving the production of short hairpin RNA (shRNA). We investigated an attractive therapeutic approach to target the expression of proinflammatory GMF by using lentiviral vector encoding GMF-specific shRNA to reduce GMF levels in the spinal cord and brain of mice. To determine the effect of GMF-shRNA on GMF protein levels, we performed quantitative ELISA analysis in brain and in thoracic, cervical and lumbar regions of spinal cord from mice followed by GMF-shRNA (G-shRNA) or control shRNA (C-shRNA) treatments. Our results show a marked reduction of GMF protein levels in brain and spinal cord of mice treated with GMF-shRNA compared to control shRNA treatment. Consistent with the GMF protein analysis, the immunohistochemical examination of the spinal cord sections of EAE mice treated with GMF-shRNA showed significantly reduced GMF-immunoreactivity. Thus, the down-regulation of GMF by GMF-shRNA was efficient and wide spread in CNS as evident by the significantly reduced levels of GMF protein in the brain and spinal cord of mice.
