Augmented anti-tumor effect of dendritic cells genetically engineered by interleukin-12 plasmid DNA.
The objective of this study was to genetically engineer dendritic cells (DC) for biological activation and evaluate their anti-tumor activity in a tumor-bearing mouse model. Mouse DC were incubated on the surface of culture dishes which had been coated with the complexes of a cationized dextran and luciferase plasmid DNA complexes plus a cell adhesion protein, Pronectin, for gene transfection (...
background: phytoestrogens, a group of plant-derived polyphenolic compounds have recently come into considerable attention due to the increasing information on their potential adverse effects in human health. some of phytoestrogens show estrogenic activity that may be carcinogenic for human. in the present study, we investigated the transcriptional effects of variety of phytoestrogens on the bo...
Herein, we present the design and synthesis of new redox-active monomeric and dimeric (gemini) cationic lipids based on ferrocenylated cholesterol derivatives for gene delivery. The cationic cholesterols are shown to be transfection efficient after being formulated with the neutral helper lipid DOPE in the presence of serum (FBS). The redox activity of the resulting co-liposomes and their lipop...
Background Hepatocellular carcinoma (HCC) is a high-incidence and significant cause of cancer globally. HCC the world's third most common death-related sixth tumor. In HCC, various cellular signaling activated to ensure malignancy transformation, angiogenesis, metastasis. The efficient pathway in mitogen-activated protein kinase (MAPK), which controls regulates apoptosis. mutant k-ras gene led ...
The efficiency of the transfection of a plasmid DNA encoding a galactosidase promoted by a series of pyridinium lipids in mixtures with other cationic lipids and neutral lipids was assessed in CHO-K1 cells. We identify key molecular parameters of the lipids in the mixture - clog P, lipid length, partial molar volume - to predict the morphology of the lipid-DNA lipoplex and then correlate these ...
objective: dna vaccines have been widely used to develop immunity against various pathogens including parasites and viruses. the potential of dna vaccine to induce an effective immune response is related to the expression levels of the encoded protein in eukaryotic cells. therefore, optimization of plasmid dna delivery system is a major concern in protein expression in order to make an efficien...
Objective(s): PEI based nanoparticle (NP) due to dual capabilities of proton sponge and DNA binding is known as powerful tool for nucleic acid delivery to cells. However, serious cytotoxicity and complicated conditions, which govern NPs properties and its interactions with cells practically, hindered achievement to high transfection efficiency. Here, we have tried to optimize the properties of ...
