A platform of high-efficiency nonviral gene transfer in mouse osteoblast cells in vitro.
Article in Molecular biotechnology, 2006. 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
We have previously established mouse genetic models and identified the genetic components of quantitative trait loci (QTL) on mouse chromosomes that contribute to phenotypes such as bone size, bone density, and bone's anabolic response to mechanical loading. However, these regions contain dozens of unknown genes that are needed for functional testing. In this study, we provided a protocol of nucleoporation with high efficiency by using a commercial nucleofection buffer and Gene Pulser to deliver a test gene into bone cells for functional studies. We cloned an osteoblast differentiation-specific gene osterix (Osx) from a mouse bone cDNA library into a pHGCX expression vector and used nucleoporation to deliver pHGCX/ Flag-Osx into the nuclei of MC3T3-E1 cells. We then examined the transfection efficiency, transgene expression, and function. Our results have demonstrated that nucleoporation can deliver a transgene into MC3T3-E1 osteoblast cells with approx 94% transfection efficiency, and express a functional Flag-Osx fusion protein capable of inducing cell differentiation as measured by an increase in alkaline phosphatase (ALP) activity. Therefore, this experimental system provides a rapid, safe, and efficient cell-based model of high-throughput phenotypic screening to identify candidate genes from physically mapped regions that are important for osteoblast differentiation.
