Stimulus-responsive nano lipidosome for enhancing the anti-tumour effect of a novel peptide Dermaseptin-PP.
Article in IET nanobiotechnology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 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
objectiveDermaseptin-PP is a newly discovered anticancer peptide with a unique antitumour mechanism and remarkable effect. However, this α-helix anticancer peptide risks haemolysis when used at high doses, which limits its further application. This study aims to prepare a pH-responsive liposome, Der-loaded-pHSL, using nanotechnology to avoid the haemolysis risk of Dermaseptin-PP and increase its accumulation in tumour sites to enhance efficacy and reduce toxicity.
methodsThe characterisation of Der-loaded-pHSL was carried out employing preparation. The effect of haemolysis and tumour inhibition were investigated by in vitro haemolysis assay and cytotoxicity assay. The cell uptake under different pH conditions was investigated by flow cytometry, and the effect of pH on tumour cell selectivity was evaluated. In order to evaluate the in vivo targeting and antitumour effect of Der-loaded-pHSL, the in vivo distribution experiment and the pharmacodynamic experiment were performed using the nude mouse tumour model.
resultsThe preparation method of the Der-loaded-pHSL is simple, and the liposome has good nanoparticle characteristics. When Dermaseptin-PP was prepared as liposome, haemolysis was significantly decreased, and tumour cell inhibition was significantly enhanced. Compared with ordinary liposomes, this change was more significant in Der-loaded-pHSL. The uptake of pH-sensitive liposomes was higher in the simulated acidic tumour microenvironment, and the uptake showed a specific acid dependence. In vivo experiments showed that Der-loaded-pHSL had a significant tumour-targeting effect and could significantly enhance the antitumour effect of Dermaseptin-PP.
conclusionDer-loaded-pHSL designed in this study is a liposome with a quick, simple, effective preparation method, which can significantly reduce the haemolytic toxicity of Dermaseptin-PP and enhance its antitumour effect by increasing the tumour accumulation and cell intake. It provides a new idea for applying Dermaseptin-PP and other anticancer peptides with α-helical structure.
