The Efficiency of CD40 Down Regulation by siRNA and Antisense ODN: Comparison of Lipofectamine and FuGENE6
Background: Dendritic cells (DCs) are ideal accessory cells in the field of gene therapy. Delivery of DNA and siRNA into mammalian cells is a useful technique in treating various diseases caused by single gene defects. Selective gene silencing by small interfering RNAs (siRNAs) and antisense oligodeoxynucleotides (ODN)s is an efficient method for the manipulation of cellular functions. An effic...
متن کاملGold nanoclusters-assisted delivery of NGF siRNA for effective treatment of pancreatic cancer
Pancreatic cancer is one of the deadliest human cancers, whose progression is highly dependent on the nervous microenvironment. The suppression of gene expression of nerve growth factor (NGF) may have great potential in pancreatic cancer treatment. Here we show that gold nanocluster-assisted delivery of siRNA of NGF (GNC-siRNA) allows efficient NGF gene silencing and pancreatic cancer treatment...
متن کاملFormulation of a therapeutic cationic liposome-siRNA complex for development to fight osteosarcoma
Introdution: Cationic liposomes have been presented for gene delivery as an alternative vector instead of viral vectors. A major challenge associated with siRNA delivery is the instability of liposomes, which is still a serious problem. The aim of this study was to provide an appropriate formulation to overcome this instability. Methods: In the present study (Scientific-Fundamental, Experiment...
متن کاملNanolipoparticles-mediated MDR1 siRNA delivery: preparation, characterization and cellular uptake
Objective(s): Lipid-based nanoparticles (NLP) are PEGylated carriers composed of lipids and encapsulated nucleic acids with a diameter less than 100 nm. The presence of PEG in the NLP formulation improves the particle pharmacokinetic behavior. The purpose of this study was to prepare and characterize NLPs containing MDR1 siRNA and evaluate their cytotoxicity and cellular uptake. MDR1 siRNA coul...
متن کاملNanolipoparticles-mediated MDR1 siRNA delivery reduces doxorubicin resistance in breast cancer cells and silences MDR1 expression in xenograft model of human breast cancer
Objective(s): P-glycoprotein (P-gp) is an efflux protein, the overexpression of which has been associated with multidrug resistance in various cancers. Although siRNA delivery to reverse P-gp expression may be promising for sensitizing of tumor cells to cytotoxic drugs, the therapeutic use of siRNA requires effective carriers that can deliver siRNA intracellularly with minimal toxicity on targe...
