Suppression of the progress of disseminated pancreatic cancer cells by NK4 plasmid DNA released from cationized gelatin microspheres.
Article in Pharmaceutical research, 2004. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
purposeNK4, composed of the NH2-terminal hairpin and subsequent four-kringle domains of hepatocyte growth factor (HGF), acts as a potent angiogenesis inhibitor. This study is an investigation to evaluate the feasibility of controlled release of NK4 plasmid DNA in suppressing the tumor growth. Controlled release by a biodegradable hydrogel enabled the NK4 plasmid DNA to exert the tumor suppression effects.
methodsBiodegradable cationized gelatin microspheres were prepared for the controlled release of an NK4 plasmid DNA. The cationized gelatin microspheres incorporating NK4 plasmid DNA were subcutaneously injected to tumor-bearing mice to evaluate the suppressive effects on tumor angiogenesis and growth.
resultsThe cationized gelatin microspheres incorporating NK4 plasmid DNA could release over 28 days as a result of microspheres degradation. The injection of cationized gelatin microspheres incorporating NK4 plasmid DNA into the subcutaneous tissue of mice inoculated with pancreatic cancer cells prolonged their survival time period. An increase in the tumor number was suppressed to a significantly greater extent than free NK4 plasmid DNA. The controlled release of NK4 plasmid DNA suppressed angiogenesis and increased the cell apoptosis in the tumor tissue while it enhanced and prolonged the NK4 protein level in the blood circulation.
conclusionsWe conclude that the controlled release technology is promising to enhance the tumor suppression effects of NK4 plasmid DNA.
