Human erythropoietin gene delivery using an arginine-grafted bioreducible polymer system.
Article in Molecular therapy : the journal of the American Society of Gene Therapy, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 6 papers.
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
Erythropoiesis-stimulating agents are widely used to treat anemia for chronic kidney disease (CKD) and cancer, however, several clinical limitations impede their effectiveness. Nonviral gene therapy systems are a novel solution to these problems as they provide stable and low immunogenic protein expression levels. Here, we show the application of an arginine-grafted bioreducible poly(disulfide amine) (ABP) polymer gene delivery system as a platform for in vivo transfer of human erythropoietin plasmid DNA (phEPO) to produce long-term, therapeutic erythropoiesis. A single systemic injection of phEPO/ABP polyplex led to higher hematocrit levels over a 60-day period accompanied with reticulocytosis and high hEPO protein expression. In addition, we found that the distinct temporal and spatial distribution of phEPO/ABP polyplexes contributed to increased erythropoietic effects compared to those of traditional EPO therapies. Overall, our study suggests that ABP polymer-based gene therapy provides a promising clinical strategy to reach effective therapeutic levels of hEPO gene.
