Tumor necrosis factor-alpha (TNF-alpha) is one of the major cytokines that modulate the immune response in viral myocarditis, but its role has not yet been thoroughly evaluated. We antagonized TNF-alpha using the expressed soluble p75 TNF receptor linked to the Fc portion of the human IgG1 gene (sTNFR:Fc) by in vivo electroporation, and evaluated its(More)
BACKGROUND The inflammatory cytokines have an important role in the pathogenesis of viral myocarditis. Inerleukin-1 (IL-1) is one of the major cytokines that modulate the outcome of viral infection. Among the methods for in vivo gene transfer, direct injection of plasmid DNA is one that is simple and feasible. In this study, we expressed human IL-1 receptor(More)
OBJECTIVE To determine the efficacy of local therapy with human angiostatin gene in murine collagen-induced arthritis (CIA). METHODS DBA/1 mice were immunized with bovine type II collagen. Before the onset of arthritis, NIH3T3 fibroblasts, transduced with angiostatin-expressing retroviral vectors or control vectors, were transplanted into the knee cavity.(More)
Recombinant human interleukin-11 (rhIL-11) has been shown to increase platelet counts in animals and humans and is the only drug approved for its use in chemotherapy-induced thrombocytopenia (CIT). However, due to its serious side effects, its clinical use has been limited. The current work presents significantly improved efficacy of rhIL-11 via knowledge(More)
BACKGROUND The purpose of the present phase I clinical trial was to evaluate the safety, tolerability, and preliminary efficacy of naked DNA therapy expressing two isoforms of hepatocyte growth factor (pCK-HGF-X7) in critical limb ischemia (CLI) patients. MATERIALS AND METHODS Twenty-one patients with CLI were consecutively assigned to receive increasing(More)
Rheumatoid arthritis (RA) is a chronic inflammatory joint disease, leading to cartilage and bone destruction. We investigated whether the electrotransfer of IL-4 DNA could regulate the disease progress of murine collagen-induced arthritis (CIA). The maximum serum level of mIL-4 was measured by 340 pg/ml on day 1 following DNA transfer. The onset of severe(More)
The aim of this study is to evaluate the efficacy and safety of genetically modified recombinant human IL-11 (mIL-11), using original IL-11 as an active control, in a multicenter randomized trial involving 88 cancer patients undergoing chemotherapy Eighty-eight subjects who had platelets ≦75 × 109/L during the prior chemotherapy were randomized to the MR or(More)
Most of the previous studies in which cytokine DNA plasmids were delivered by systemic administration exhibited only marginal therapeutic effects, if any, in the EAE model. One strategy to overcome this limitation would be to determine the optimal delivery route leading to significant beneficial effects both in early (prophylactic) and late (therapeutic)(More)
BACKGROUND It has previously been demonstrated that high levels of gene expression in skeletal muscles can be achieved after direct in vivo electrotransfer of naked plasmid DNA. The purpose of this study is to examine the potential of in vivo electroporation of plasmid DNA encoding human IL-1Ra for the prevention of murine collagen-induced arthritis (CIA).(More)
BACKGROUND In the present study, we determined the effects of HX108-CS (mixed extract of Schisandra chinensis and Chaenomeles sinensis) supplementation on lactate accumulation and endurance capacity. Furthermore, we examined CK (creatine kinase), LDH (lactate dehydrogenase) activity to determine whether the HX108-CS affected markers of skeletal muscle(More)
