poly(a) polymerase from vaccinia virus-infected cells. i. partial purification and characterization.poly(a) polymerase activity is induced during vaccinia virus infection of hela cells. the enzyme is maximally induced at 3.5 h postinfection. partial purification frees the preparation of rnase activity and rna polymerase activity. atp is the substrate for poly(a) synthesis. a small amount of poly(a) is produced from added adenosine diphosphate due to the production of atp by an adenylate kinase present in the preparation. the incorporation of atp into poly(a) is dependent on divalent cations (m ...19744417406
poly(a) polymerase from vaccinia virus-infected cells. ii. product and primer characterization.the product of the in vitro reaction of a vaccinia virus-induced poly(a) polymerase (see preceding paper) with atp is shown to be poly(a) by nuclease resistance and by annealing with poly(u). polyacrylamide gel electrophoresis indicates that the in vitro synthesized poly(a) is associated with large rna which is sensitive to rnase. rna which co-purifies with the virus-induced enzyme is similar to vaccinia virus-specific rna with respect to size and poly(a) content. double labeling studies indicat ...19744417407

detection of polyadenylic acid sequences in viral and eukaryotic rna(polu(u)-cellulose columns-poly(u) filters-fiberglass-hela cells-bacteriophage t4).a rapid and specific technique to detect polyriboadenylic acid sequences in rna is described. the method depends upon the ability of rnas that contain poly(a) sequences to associate specifically with poly(u) that has been immobilized on fiberglass filters by ultraviolet irradiation. a high proportion of the transcripts synthesized in vivo and in vitro from the vaccinia virus genome contain poly(a) sequences and bind to the poly(u) filters. similarly, dna-like rna from the nucleus and from the cy ...19724501121
selective increase in lymphocyte interferon response to vaccinia antigen after revaccination.viral antigen prepared by heat inactivation of vaccinia virus stimulated production of interferon in association with transformation of sensitized human lymphocytes in vitro. involvement of a macrophage-lymphocyte interaction in production of interferon stimulated by viral antigen was found in which macrophage greatly augmented the amount of interferon produced by lymphocytes. reimmunization with live vaccinia virus resulted in a selective increase in the ability of lymphocytes to produce interf ...19724506785

biogenesis of poxviruses: inactivation of host dna polymerase by a component of the invading inoculum particle.inhibition of nuclear dna polymerase activity in cells infected with vaccinia virus parallels the development of a nuclease activity similar to one associated with the virus particles. both phenomena occur in the absence of protein synthesis, implying that incoming particles are responsible for the effects observed. experimental evidence is presented indicating that the nuclear dna polymerase activity is inhibited coincidentally with, and perhaps as a consequence of, the hydrolysis of nascent, s ...19734515931

breakdown of hela cell dna mediated by vaccinia virus.breakdown of hela cell dna begins within 90 min after infection with vaccinia virus at a multiplicity of infection of 2-plaque-forming units per cell, and ends about 7.5 hr after infection. hela cell dna is degraded to a uniform size of 1 to 2 x 10(7) daltons, as judged by alkaline sucrose sedimentation analysis. the rate of host-cell dna degradation by vaccinia virus increased directly with the multiplicity of infection. sedimentation patterns in neutral and alkaline sucrose gradients of viral ...19734522298

some factors determining differences in the antigenicity of vaccinia virus strains.the causes determining differences in the antigenicity of different strains of vaccinia virus were investigated in rabbits. a relationship between the antigenicity of a strain and its capacity to multiply in immunized animals was established. inactivated preparations of the viruses under investigation were capable of stimulating the production of virus neutralizing antibody in vaccinated rabbits. the virus showed the greatest accumulation and the longest persistence in animals vaccinated with th ...19724537479

specific macrophage immunity to vaccinia virus: macrophage-virus interaction.macrophage immunity to vaccinia virus was examined by measuring replication of vaccinia virus in immune and nonimmune rabbit peritoneal macrophages. vaccinia virus multiplied in macrophages from normal rabbits but failed to replicate in macrophages from immune rabbits. the specificity of vaccinia restriction was demonstrated by the ability of myxoma virus to replicate in nonimmune and vaccinia-immune macrophages. vaccinia virus absorbed equally well to immune and nonimmune macrophages, but only ...19724564156
cytotoxic antibody response to tumors induced in adult and newborn rabbits by fibroma virus.cells cultured from tumors induced in rabbits by inoculation of fibroma virus possessed virus-specific cell surface and cytoplasmic antigens. tumor cell cultures were capable of a limited number of cell divisions before degenerating. employing the (51)cr-release test and the microcytotoxicity test, it was demonstrated that sera from rabbits with regressed fibroma tumors contained antibodies cytotoxic for cells infected in culture with fibroma virus. these sera were only weakly cytotoxic for cult ...19724564289

iron-binding catechols and virulence in escherichia coli.a comparison of viral-induced unresponsiveness of phytohemagglutinin (pha)-induced deoxyribonucleic acid (dna) synthesis of mouse lymphocytes was made by culturing the cells under identical conditions in the presence of hepes buffer in a humid-air atmosphere. the degree of pha-induced dna synthesis was found to vary, depending upon the type of ribonucleic acid or dna virus treatment. myxovirus, paramyxoviruses, mengo virus, leukemic viruses, herpesvirus, and vaccinia virus caused a depression in ...19734576680
