Nondefective spleen necrosis virus-derived vectors define the upper size limit for packaging reticuloendotheliosis viruses.
We constructed a nondefective retrovirus vector based on spleen necrosis virus (SNV), a replication-competent reticuloendotheliosis virus. We introduced different DNA sequences into this vector and studied the ability of the resulting viruses to replicate in chicken embryo fibroblasts. The replication efficiency of SNV-derived viruses decreased with increasing virus size. Viruses larger than 9....
متن کاملReticuloendotheliosis Viruses, and Chicken Cells
Antibodies against a large and a small DNA polymerase isolated from chicken embryos and against avian myeloblastosis virus DNA polymerase were used to study the serological relationships of the DNA polymerase activities of three avian systems with RNA and a DNA polymerase-avian leukosis-sarcoma viruses, reticuloendotheliosis viruses, and a fraction from uninfected chicken cells. The DNA polymer...

متن کاملReticuloendotheliosis viruses and derived vectors for human gene therapy.
The reticuloendotheliosis viruses (REV) spleen necrosis virus (SNV) and reticuloendotheliosis virus strain-A (REV-A) are amphotropic retroviruses which infect a large variety of cells of avian and some mammalian species. They normally do not infect primate or rodent cells. However, they efficiently infect and integrate their genome into that of human cells when they are pseudotyped with the env...
متن کاملInhibition of hepatic phosphoenolpyruvate carboxykinase by avian reticuloendotheliosis viruses.
Severe weight loss is associated with many malignant diseases of humans and animals. Avian reticuloendotheliosis viruses (RE viruses) induce runting in experimentally infected chickens. Chickens infected with a replication-competent RE virus, reticuloendotheliosis-associated virus, weighed 30-50% less than control birds at the time of death. Chickens infected with reticuloendotheliosis virus, a...
