Dendritic cells (DCs) are capable of presenting tumor-associated antigens and subsequently play an essential role in T-cell activation. The aim of this study was to develop an efficient method for gene transfer into DCs. These genetically transduced DCs can then be used as potent inducers of specific cell-mediated immune response. When compared with physical methods for gene transfer (lipofecti...

Prostate cancer is the most commonly diagnosed and second leading cause of mortality in men Western World. In initial stages, prostate dependent on androgens for growth which basis androgen ablation therapy. The effects are mediated by Androgen Receptor (AR). Therefore, studies focus identification AR-regulated genes that also highly expressed prostate. STAMP family STAMP1/STEAP2 STAMP2/STEAP4 ...

Cell surface-bound receptors represent suitable entry sites for gene delivery into cells by receptor-mediated endocytosis. Here we have taken advantage of the mannose receptor that is highly expressed on antigen-presenting dendritic cells for targeted gene transfer by employing mannosylpolyethylenimine (ManPEI) conjugates. Several ManPEI conjugates were synthesized and used for formation of Man...

BACKGROUND Eukaryotic cells arose through the uptake of bacterial endosymbionts and their gradual conversion into cell organelles (mitochondria and chloroplasts). In this process, a massive transfer of genes from the genome of the endosymbiont to the nuclear genome of the host cell occurred. Whereas intron-free organellar genes could conceivably enter the nucleus as DNA pieces and become functi...

Agrobacterium-mediated gene transfer is widely used for plant molecular genetics, and efficient techniques are required. Recent studies show that ethylene inhibits the gene transfer. To suppress ethylene evolution, we introduced 1-aminocyclopropane-1-carboxylate (ACC) deaminase into Agrobacterium tumefaciens. The ACC deaminase enhanced A. tumefaciens-mediated gene transfer into plants.

In this study, we evaluated the effect of blood components (whole blood and serum) on asialoglycoprotein receptor-mediated in vivo gene transfer. The hepatic transfection activity of galactosylated lipoplex preincubated with serum was approximately 10 times higher than that without incubation after intraportal injection in mice. However, preincubation with whole blood significantly reduced hepa...

Adenoviral vectors are a widely used means of gene transfer. However, transgene expression after adenoviral administration varies among different carcinoma cell lines. We hypothesized that this variation is attributable, in part, to the presence of cell surface molecules involved in adenoviral infection. To test this, we first assessed adenovirus-mediated transgene expression in four human lung...

OBJECTIVE The ability to transfer genes to adult myocardium may have therapeutic implications for cardiac transplantation. We investigated the feasibility of adenovirus-mediated transfer of marker genes LacZ and Luciferase, as well as the potentially therapeutic gene of the human beta2-adrenergic receptor in a rat heterotopic heart transplant model. METHODS Donor hearts were flushed with 10(1...
