Persistence of avian oncoviruses in chicken macrophages.
Inoculation of avian oncoviruses into 1- to 2-month old chickens led to a rapid production of antiviral humoral antibodies. Under these conditions it was found that avian leukosis viruses are sequestered in macrophages of peripheral blood, in which they can persist for a long period of time (up to about 3 years). In contrast, avian sarcoma viruses were never found in macrophages from chickens d...
متن کاملIntracellular precursors to the major glycoprotein of avian oncoviruses in chicken embryo fibroblasts.
A 96,000-dalton glycoprotein, p(96), was present in cell extracts obtained from gs-chf- chicken embryo fibroblasts infected with the avian RNA tumor viruses Rous-associated virus-2 subgroup B (RAV-2) and the Schmidt-Ruppin strain of Rous sarcoma virus subgroup A (SR-RSV-A), as well as from uninfected gsLchf+ (HE) cell extracts. It was not found in cell extracts from uninfected gs-chf- or gs+chf...
متن کاملOncoviruses and Pathogenic MicroRNAs in Humans
For disease prognosis, the functional significance of the oncoviral integration locus in oncogenesis has remained enigmatic. The locus encodes several transcripts without protein products, but microRNAs (miRNAs) have recently been identified from a common oncoviral integration locus. miRNA is an endogenous, non-coding small RNA by which gene expression is suppressed. Although miRNA genes, such ...
متن کاملMarek's disease virus Meq transforms chicken cells via the v-Jun transcriptional cascade: a converging transforming pathway for avian oncoviruses.
Marek's disease virus (MDV) is a highly pathogenic and oncogenic herpesvirus of chickens. MDV encodes a basic leucine zipper (bZIP) protein, Meq (MDV EcoQ). The bZIP domain of Meq shares homology with Jun/Fos, whereas the transactivation/repressor domain is entirely different. Increasing evidence suggests that Meq is the oncoprotein of MDV. Direct evidence that Meq transforms chicken cells and ...
