Abstract

This study reports the potential of cold atmospheric plasma (CAP) as a versatile tool for delivering oligonucleotides into mammalian cells. Compared to lipofection and electroporation methods, plasma transfection showed a better uptake efficiency and less cell death in the transfection of oligonucleotides. We demonstrated that the level of extracellular aqueous reactive oxygen species (ROS) produced by gas plasma is correlated with the uptake efficiency and that this is achieved through an increase of intracellular ROS levels and the resulting increase in cell membrane permeability. This finding was supported by the use of ROS scavengers, which reduced CAP-based uptake efficiency. In addition, we found that cold atmospheric plasma could transfer oligonucleotides such as siRNA and miRNA into cells even in 3D cultures, thus suggesting the potential for unique applications of CAP beyond those provided by standard transfection techniques. Together, our results suggest that cold plasma might provide an efficient technique for the delivery of siRNA and miRNA in 2D and 3D culture models.

  • In a recent study, gas plasma-facilitated cellular transfection reached siRNA extinction efficiency of about 20% and plasmid transfection efficiency of less than 5% in a 3D culture system, compared with more than 80% and more than 40% in the present system.

    “Moreover, in a recent study (36) demonstrating the benefits of a novel gas plasma-facilitated cellular transfection method, siRNA extinction efficiency of about 20% (as compared to more than 80% in our system) and plasmid transfection efficiency of less than 5% (as compared to more than 40% in our system) were reached in a 3D culture system.”

    From Direct transfection of clonal organoids in Matrigel microbeads: a promising approach toward organoid-based genetic screens (2018) · cites this paper as [36]

    The Results (page unavailable) report gas plasma-facilitated delivery of siRNA in 3D cultures and relatively poor plasmid transfection in both 2D and 3D cultures. They do not state about 20% siRNA extinction or less than 5% plasmid transfection; the Methods describe measuring siRNA uptake, not siRNA extinction. The figures cited in the Results do not supply those percentages in our text copy. (LLM, conf=0.83)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
