PURPOSE Cationic gemini surfactants have been studied as non-viral vectors for gene therapy. Clinical applications of cationic lipid/DNA lipoplexes are restricted by their instability in aqueous formulations. In this work, we investigated the influence of lyophilization on the essential physiochemical properties and in vitro transfection of gemini surfactant-lipoplexes. Additionally, we evaluat...
Transfection of HC-11 murine epithelial mammary cells as well as murine and sheep mammary glands were carried out using insulin-containing constructs that deliver DNA by receptor-mediated endocytosis to receptor-expressing cells. In vivo transfection of mammary gland tissue with the luciferase gene was carried out by introducing the DNA constructs into the mammary ducts of both mice and sheep. ...
amphiphilic cationic micelles have recently attracted much attention as non-viral vector. in the current study the retinoic acid-g-chitosan (ra-chitosan) micelles have been used as novel gene carriers. uptake of micelles, condensation ability and transfection efficiency of micelle–dna complexes (miceplexes) in the presence or absence of serum had been investigated on hela and hepg2 cell lines. ...
Angiotensin I-converting enzyme (ACE) is a key enzyme in the regulation of systemic blood pressure and plays a major role in the renin-angiotensin and bradykinin-kinin systems, at the luminal surface of the vascular endothelia. To identify the promoter region, the transcription regulatory elements and the cell specificity of the ACE gene, five successive DNA deletions of the 5' upstream region ...
background: the aim of this study was optimization of the polyfect gene delivery method of pcdna3.1 expression vector transfected with the mouse pdx-1 gene in three different kinds of mesenchymal stem cells and hepa cells as well as comparison of transfection efficiency leading to expression of the mentioned gene in the cell types used. materials and methods: rat bone marrow-derived mesenchymal...
Redox regulation of transcription factors has recently been demonstrated for AP-1, NF-kappaB, Sp-1 and glucocorticoid receptor in vitro and in vivo. The redox state in estrogen-dependent cells possibly influences the function of estrogen receptor (ER), and the regulation of the function of ER is essential for understanding of growth and differentiation of these cells, as well as promotion and p...
Naturally occurring 3-alkylpyridinium polymers from the marine sponge Reniera sarai are membrane-active compounds exerting a selective cytotoxicity towards non small cell lung cancer cells, and stable transfection of nucleated mammalian cells. In view of their possible use as chemotherapeutics and/or transfection tools, three poly-APS based synthetic compounds were tested on their activity usin...
