Bioactive macromolecular peptides and oligonucleotides have significant therapeutic potential. However, due to their size, they have no ability to enter the cytoplasm of cells. Peptide/Protein transduction domains (PTDs), also called cell-penetrating peptides (CPPs), can promote uptake of macromolecules via endocytosis. However, overcoming the rate-limiting(More)
With the emergence of new viruses, such as the SARS virus and the avian influenza virus, the importance of investigations on the genetic basis of viral infections becomes clear. Sendai virus causes a localized respiratory tract infection in rodents, while a mutant, F1-R, causes a systemic infection. It has been suggested that two determinants are(More)
INTRODUCTION Cancer cells arise from normal cells that have incurred mutations in oncogenes and tumor suppressor genes. The mutations are often unique and not readily found in normal cells, giving rise to the opportunity of exploiting these mutations to induce synthetic lethality. Synthetic lethality occurs when inhibition or mutation in two or more(More)
RNA interference (RNAi) has great potential to treat human disease. However, in vivo delivery of short interfering RNAs (siRNAs), which are negatively charged double-stranded RNA macromolecules, remains a major hurdle. Current siRNA delivery has begun to move away from large lipid and synthetic nanoparticles to more defined molecular conjugates. Here we(More)
Allograft inflammatory factor-1 (AIF1) is a cytoplasmic scaffold protein shown to influence immune responses in macrophages and microglial cells. The protein contains Ca2+ binding EF-hand and PDZ interaction domains important for mediating intracellular signaling complexes. This study now reports that AIF1 is expressed in CD11c+ dendritic cells (DC) and(More)
