PURPOSE To investigate the feasibility of magnetic resonance (MR) electric impedance tomography ( EIT electric impedance tomography ) technique for in situ monitoring of electric field distribution during in vivo electroporation of mouse tumors to predict reversibly electroporated tumor areas. MATERIALS AND METHODS All experiments received institutional(More)
Electroporation (EP) is a physical method for the delivery of molecules into cells and tissues, including the skin. In this study, in order to control the degree of transdermal and topical drug delivery, EP at different amplitudes of electric pulses was evaluated. A new in vivo real-time monitoring system based on fluorescently labeled molecules was(More)
BACKGROUND.: Electrochemotherapy provides good local tumor control but requires adjuvant treatment for increased local response and action on distant metastasis. In relation to this, intramuscular interleukin-12 (IL-12) gene electro-transfer, which provides systemic shedding of IL-12, was combined with local electrochemotherapy with cisplatin. Furthermore,(More)
The data on the biological responsiveness of melanoma and endothelial cells that are targeted by Antiangiogenic MEtargidin Peptide (AMEP) are limited; therefore, the antiproliferative, antimetastatic and antiangiogenic effects of AMEP were investigated in murine melanoma and human endothelial cells after plasmid AMEP gene electrotransfer into the cells in(More)
Gene therapy with Plasmid AMEP (antiangiogenic metargidin peptide) has recently been studied as a potential targeted therapy for melanoma. This plasmid is designed to downregulate α5β1 and αvβ3 integrins. In our study, electroporation was used as a nonviral delivery system. We investigated the antiangiogenic and direct antitumor effectiveness of this gene(More)
In order to ensure safe, efficient and controlled gene delivery to skin, the improvement of delivery methods together with proper design of DNA is required. Non-viral delivery methods, such as gene electrotransfer, and the design of tissue-specific promoters are promising tools to ensure the safety of gene delivery to the skin. In the scope of our study, we(More)
The regulatory requirements for genotoxicity testing rely on a battery of genotoxicity tests, which generally consist of bacterial and mammalian cell assays for detection of gene mutations and chromosomal aberrations. However, for rapid screening, these methods are not appropriate. We have developed a new cell-based biosensor system that provides rapid and(More)
New targets and therapeutic approaches for vascular targeted strategies in oncology are continuously explored. Endoglin, a co-receptor of TGF-β, is a known target, however, its silencing with vector-based RNA interference technology has not been evaluated yet. Therefore, in our study, we assembled plasmid DNA coding for shRNA against endoglin, and used gene(More)
Biomedical applications of plasma require its efficacy for specific purposes and equally importantly its safety. Herein the safety aspects of cold plasma created with simple atmospheric pressure plasma jet produced with helium gas and electrode discharge are evaluated in skin damage on mouse, at different duration of exposure and gas flow rates. The extent(More)
Skin is an attractive target for gene electrotransfer. It consists of different cell types that can be transfected, leading to various responses to gene electrotransfer. We demonstrate that these responses could be controlled by selecting the appropriate electrotransfer parameters. Specifically, the application of low or high electric pulses, applied by(More)
