Relationship of the feline oncornavirus associated cell membrane antigen to a feline sarcoma virus encoded polyprotein.
The feline oncornavirus associated cell membrane antigen (FOCMA) is expressed on the membranes of cells transformed by infection with the feline leukemia virus (FOCMA-L) or feline sarcoma virus (FOCMA-S) (Hardy et al. 1977; Essex et al. 1977). Expression of FOCMA is transformation-specific and not dependent upon concomitant expression of antigens associated with feline leukemia virus (FeLV) or ...
متن کاملCells nonproductively transformed by Abelson murine leukemia virus express a high molecular weight polyprotein containing structural and nonstructural components.
Cell clones nonproductively transformed by the replication-defective Abelson strain of murine leukemia virus (AbLV) were analyzed for type C viral antigen expression by competition immunoassay. AbLV-transformed mink non-producer lines were found to express a 110,000- to 130,000-molecular weight polyprotein containing murine leukemia virus gag proteins p15 and p12 covalently linked to nonstructu...
متن کاملMurine leukemia virus (T-8)-transformed cells: identification of a precursor polyprotein containing gag gene-coded proteins (p15 and p12) and a nonstructural component.
Mink cells nonproductively transformed by the T-8 strain of mink cell focus-inducing virus express two type C viral amino terminal gag gene-coded structural proteins, p15 and p12, in the form of a 90,000 to 110,000 molecular weight polyprotein that lacks detectable immunological reactivity with other known type C virus-coded translational products. The observation concurs with the previous demo...
متن کاملIsolation, Characterization and Standardization of New Infectious Bursal Disease Virus for Development of a Live Vaccine
Background and Aims: Infectious bursal disease (IBD) is an acute contagious viral disease of birds worldwide. The causative virus induces a persistent immune suppression following destroy B lymphocytes precursors in bursal lymphoid follicles. Vaccination is the main strategy for prevention of the disease in commercial poultry industry. Materials and Methods: To produce a live vaccine against th...
متن کاملMcDonough feline sarcoma virus: characterization of the molecularly cloned provirus and its feline oncogene (v-fms).
The genetic structure of the McDonough strain of feline sarcoma virus (SM-FeSV) was deduced by analysis of molecularly cloned, transforming proviral DNA. The 8.2-kilobase pair SM-FeSV provirus is longer than those of other feline sarcoma viruses and contains a transforming gene (v-fms) flanked by sequences derived from feline leukemia virus. The order of genes with respect to viral RNA is 5'-ga...
