Few studies have directly compared the efficiencies of gene delivery methods that target normal lung cells versus lung tumor cells. We report the first study directly comparing the efficiency and toxicity of viral [adeno-associated virus (AAV2, 5, 6) and lentivirus], nonviral (Effectene, SuperFect and Lipofectamine 2000) and physical [particle-mediated gene transfer (PMGT)] methods of gene deli...

The aim of the present study was to evaluate the efficacy of novel nonviral gene delivery systems in cells of musculoskeletal origin. Primary cultures of lapine skeletal muscle cells, lapine articular chondrocytes, human cells from fibrous dysplasia and cell lines established from human osteosarcoma (SAOS-2), chondrosarcoma (CS-1), murine skeletal myoblasts (L8) and fibroblasts (NIH 3T3) were t...

RNA interference (RNAi) enables sequence-specific, experimentally induced silencing of almost any gene by tapping into innate regulatory mechanisms that are conserved among virtually all eukaryotes. In a typical RNAi experiment, an artificial silencing trigger directs the RNAi pathway toward a target that it would not normally recognize. This is most often an endogenous protein-coding gene, alt...

The development of an efficient transfection system in livestock cells is an important step towards investigating gene transfer and the functioning and production of transgenic animals. Important factors involved in cationic liposome mediated gene transfer were evaluated through in vitro transfection of bovine, caprine and ovine fibroblast cells. Transfection of plasmid DNA complexes of differe...

Sperm mediated gene transfer can be an inexpensive and simple method in animal transgenesis; however its efficiency is poor, mainly due to the spermatozoa's lesser uptake of exogenous DNA. In the present study, the effects of lipofection and other augmentation techniques, such as sperm freezing and spermatozoa treatment with triton X100 and DMSO, on exogenous DNA uptake by sheep spermatozoa and...

The objective of this study was to obtain better antigen specific cytotoxic T cell responses in vivo. We examined the augmented induction of antigen-specific cytotoxic T cell responses to co-administration of oligonucleotides (CpG-ODN), dimethyl dioctadecyl ammonium bromide (DDA), and Lipofectamine™ 2000 with a DNA vaccine (pVAX1-CpG-Loop) and boosting with pVAX1-CpG-Loop in BALB/c mice. The re...

Colorectal cancer has been one of the most common cancers in the worldwide. Poor patient compliance and serious side effects often associated with conventional therapy (e.g. surgery, radiation, and chemotherapy). Gene therapy may be an alternative strategy. Herein, we developed a dual-targeting nanoparticle with excellent gene transfection efficiency for gene therapy of peritoneal metastasis of...

miRNA dysregulation has recently been linked to human obesity and its related complications such as type 2 diabetes. In order to study miRNA function in human adipocytes, we aimed for the modulation of mature miRNA concentration in these cells. Adipocytes, however, tend to be resistant to transfection and there is often a need to resort to viral transduction or electroporation. Our objective th...
