'Tolerance to bacterial cell wall components including lipopolysaccharide (LPS) may represent an essential regulatory mechanism during bacterial infection. Two members of the Toll-like receptor (TLR) family, TLR2 and TLR4, recognize the specific pattern of bacterial cell wall components. TLR4 has been found to be responsible for LPS tolerance. However, the ... More
Safety and short-term toxicity of a novel cationic lipid formulation for human gene therapy.
Authors:San H, Yang ZY, Pompili VJ, Jaffe ML, Plautz GE, Xu L, Felgner JH, Wheeler CJ, Felgner PL, Gao X
Journal:Hum Gene Ther
PubMed ID:8186291
'Among the potential nonviral vectors for human gene therapy are DNA-liposome complexes. In a recent clinical study, this delivery system has been utilized. In this report, a novel cationic lipid, dimyristyloxypropyl-3-dimethyl-hydroxyethyl ammonium (DMRIE), has been substituted into the DNA-liposome complex with dioleoyl phosphatidylethanolamine (DOPE), which both improves transfection efficiencies and ...

Nitrosative Stress-induced Apoptosis through Inhibition of NF-kappa B.
Authors: Marshall Harvey E; Stamler Jonathan S;
Journal:J Biol Chem
PubMed ID:12091382
'Nitrosative stress produced by cytokines predisposes to apoptotic cell death. However, the molecular mechanism by which this occurs is not well understood. We have shown previously that nitric oxide (NO) regulates the activity of the anti-apoptotic transcription factor NF-kappaB. Here we demonstrate that the inhibition of NF-kappaB by NO sensitizes ...

Evaluation of cationic liposome suitable for gene transfer into pregnant animals.
Authors:Ochiya T, Takahama Y, Baba-Toriyama H, Tsukamoto M, Yasuda Y, Kikuchi H, Terada M
Journal:Biochem Biophys Res Commun
PubMed ID:10329392
'Cationic liposome-mediated in vivo gene transfer represents a promising approach for somatic gene therapy. To assess the most suitable liposome for gene delivery into a wide range of organs and fetuses in mice, we have explored several types of cationic liposomes conjugated with plasmid DNA carrying the beta-galactosidase gene through ...

BiZyme: a novel fusion protein-mediating selection of vaccinia virus recombinants by fluorescence and antibiotic resistance.
Authors: Hansen Scott G; Cope Torrey A; Hruby Dennis E;
Journal:Biotechniques
PubMed ID:12019792
'Recombinant vaccinia virus is a useful and powerful tool for the expression and study of foreign genes. Methods that are currently available for the selection of vaccinia virus recombinants include the restoration of viral plaque-forming phenotype, the replication of viral DNA in the presence of BUdR or mycophenolic acid, and ...
