Engineering polymeric gene-delivery vectors to release an intact DNA payload at the optimal time and subcellular compartment remains a formidable challenge. An ideal vector would provide total protection of complexed DNA from degradation prior to releasing it efficiently near or within the nucleus of a target cell. While optimization of polymer properties, such as molecular weight and charge de...
Spontaneous rubella carrier cultures derived from tissues of infants with congenital rubella were studied in an attempt to elucidate a possible mechanism for viral persistence observed in these infants. Chronically infected cells were found to have a reduced growth rate and the cultures appeared to have a shortened life span. The rubella carrier state was not dependent on serum inhibitors or ru...
The growth of crystalline copper sulfide using a viral template was investigated using sequential incubation in CuCl2 and Na2S precursors. Non-specific electrostatic attraction between a genetically-modified M13 bacteriophage and copper cations in the CuCl2 precursor caused phage agglomeration and bundle formation. Following the addition of Na2S, polydisperse nanocrystals 2-7 nm in size were fo...
siRNA (small interfering RNA) interference represents an exciting new technology that could have therapeutic applications for the treatment of viral infections. However, a major challenge in the use of siRNA as a therapeutic agent is the development of a suitable delivery system. We demonstrated that a new non-viral transgene carrier, recombinant archaeal histone from the hyperthermophile Pyroc...
PREFACE 3 Preface It is indeed a pleasure to present our report of research activities 2003-2004. We thank you for your interest and your support during the last two years. We hope that this information is of use to you and look forward to continuing what has become excellent cooperation. Non viral delivery of BMP-2 plasmids with a new copolymer protected gene vector (Coprog) incorporated in a ...
Novel aerosol therapeutic modalities have been investigated for lung cancer. Inhaled gene therapy has presented safety and effectiveness previously in cystic fibrosis. However, safety concerns have been raised regarding the safety of non-viral vectors for inhaled gene therapy in lung cancer, and therefore small steps have been made towards this multifunctional treatment modality. During the las...
