The construction of siRNA plasmid targeting mouse HIF-1alpha and in vitro study of its inhibition effect.
Article in Neuroscience bulletin, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
objectiveTo construct effective RNA-interference plasmids targeting mouse HIF-1alpha gene and testify their effects and specificities in interfering HIF-1alpha expression.
methodsThree RNA-interference plasmids targeting mouse HIF-1alpha gene, pBS/U6/HIF-1alpha-siRNAI~III, were constructed and identified using double digestion method in the present study. RT-PCR, immunostaining and western blotting were employed to detect the expression alterations of HIF-1alpha in 293T cells following transfections of the three plasmids, respectively. The interference effect of pBS/U6/HIF1alphai-II in SH-SY5Y cell line was further investigated.
resultsAll the three RNA-interference plasmids, especially pBS/U6/HIF1alphai-II, showed significant inhibition in HIF-1alpha expression in 293T cell line. pBS/U6/HIF1alphai-II could also inhibit HIF-1alpha expression in SH-SY5Y cell line, in a dose-dependent way.
conclusionPlasmid pBS/U6/HIF1alphai-II constructed in our study can effectively and specifically inhibit HIF-1alpha expression, and its role in neural tube development and dysfunction will be further investigated. Construct of pBS/U6/HIF1alphai-II plasmid will provide a useful tool to study the role of HIF-1 pathway in embryogenesis, oncogenesis and ischemia development.
