This study was conducted to evaluate the ability of electroporation to efficiently transfect differentiated intestinal epithelial monolayers with plasmid DNA and to determine whether electroporation can transfect these monolayers with short-interfering RNA (siRNA) to cause gene silencing. Confluent T84 monolayers were transfected with reporter plasmids expressing luciferase or green-fluorescent...
Livin, also called melanoma inhibitor of apoptosis protein (IAP) or kidney IAP, is an anti-apoptotic protein belonging to the IAP family which consists of eight members. The genes of this family render cancer cells insensitive to apoptotic stimulation. The aim of the present study was to investigate and assess the role of siRNA in the regulation of livin gene expression in two breast cancer cel...
Cationic lipid-mediated gene transfer is widely used for their advantages over viral gene transfer because it is non-immunogenic, easy to produce and not oncogenic. The main drawback of the application of cationic lipids is their low transfection efficiency. Many reports about transfection efficiency of cationic lipids have been published in recent years. In this review, the current status and ...
PURPOSE To determine whether radiation-induced increases in nitric oxide (NO) production can influence tumor blood flow and improve delivery of Akt-targeting therapeutic DNA lipocomplexes to the tumor. METHODS AND MATERIALS The contribution of NO to the endothelial response to radiation was identified using NO synthase (NOS) inhibitors and endothelial NOS (eNOS)-deficient mice. Reporter-encod...
Development of a gene delivery system to transfer the gene of interest selectively and efficiently into targeted cells is essential for achievement of sufficient therapeutic effects by gene therapy. Here, we succeeded in developing the gene transfection method using ultrasound (US)-responsive and mannose-modified gene carriers, named Man-PEG(2000) bubble lipoplexes. Compared with the convention...
We originated and characterized melanoma cell lines derived from tumors of two feline and two canine veterinary patients. These lines reestablished the morphology, physiology and cell heterogeneity of their respective parental tumors. We evaluated the cytotoxicity of bleomycin (BLM) alone, or combined with interferon-β (IFN-β) or HSVtk/GCV suicide gene (SG) lipofection on these cells. Although ...
We describe a low-invasive gene delivery method that uses an etched atomic force microscopy (AFM) tip or nanoneedle that can be inserted into a cell nucleus without causing cellular damage. The nanoneedle is 200 nm in diameter and 6 mum in length and is operated using an AFM system. The probabilities of insertion of the nanoneedle into human mesenchymal stem cells (MSCs) and human embryonic kid...
Human papillomavirus (HPV) type 18 DNA was introduced into epithelial cell strains derived from normal and cancer tissues of human prostatectomy specimens by the lipofection transfection method. Two cell lines were established: PZ-HPV-7 (transfected normal cell) and CA-HPV-10 (transfected cancer-derived cell). These lines have been maintained for over 100 passages. Incorporation of HPV type 18 ...
OBJECTIVE Cartilage-derived morphogenetic protein 1 (CDMP1), which is a member of the transforming growth factor-beta superfamily, is an essential molecule for the aggregation of mesenchymal cells and acceleration of chondrocyte differentiation. In this study, we investigated whether CDMP1-transfected autologous bone marrow-derived mesenchymal cells (BMMCs) enhance in vivo cartilage repair in a...
Small interfering RNAs (siRNAs) are being used to induce sequence-specific gene silencing in cultured cells to study mammalian gene function. Libraries of siRNAs targeting entire human gene classes can be used to identify genes with specific cellular functions. Here we describe high-throughput siRNA delivery methods to facilitate siRNA library screening experiments with both immortalized and pr...
