virus-specific proteins synthesized in cells infected with rna+ temperature-sensitive mutants of sindbis virus.all sindbis virus temperature-sensitive mutants defective in "late" functions were systematically surveyed by acrylamide-gel electrophoresis for similarities and differences in the intracellular pattern of virus-specific proteins synthesized at the permissive and nonpermissive temperatures. only cells infected with mutants of complementation group c showed an altered pattern. at the nonpermissive temperature, these mutants failed to induce the synthesis of a polypeptide corresponding to the nucl ...19705461887
immunological activity associated with the nucleocapsid and envelope components of an arbovirus.complement-fixing antigens were detected in the nucleocapsid and envelope of sindbis virus. neutralizing antibodies are directed against antigens in the viral envelope.19705461889
allantoic fluid as a source of arbovirus hemagglutinin.noninfectious hemagglutinins were prepared from the allantoic fluids of embryonated chicken eggs infected with sindbis virus or with murray valley encephalitis virus.19705466134
molecular weight of sindbis virus ribonucleic acid as measured by polyacrylamide gel electrophoresis.the molecular weight (mw) of sindbis virion ribonucleic acid (rna) determined by gel electrophoresis was in a range of 3.89 x 10(6) to 4.45 x 10(6) daltons. upon denaturation with urea, it separated into fragments having an mw of 1.76 x 10(6) daltons. viral-specific sindbis 26s rna contained a major species having an mw of 1.76 x 10(6) daltons.19705471476

basis for variable response of arboviruses to guanidine treatment.the effect of guanidine on the replication of the group a arboviruses, sindbis virus, and semliki forest virus (sfv) was studied. guanidine rapidly, but reversibly, inhibited sfv ribonucleic acid (rna) synthesis. the synthesis of all species of viral rna was inhibited, but that of ribonuclease-resistant forms was least affected. this inhibition occurred when the drug was added at any point during the log phase of virus growth. the growth of sfv was also markedly inhibited, but sindbis virus grow ...19705530010
phospholipid synthesis in sindbis virus-infected cells.we investigated the metabolic requirements for the decrease in phospholipid synthesis previously observed by pfefferkorn and hunter in primary cultures of chick embryo fibroblasts infected with sindbis virus. the incorporation of (32)po(4) into all classes of phospholipids was found to decline at the same rate and to the same extent; thus, incorporation of (14)c-choline into acid-precipitable form provided a convenient measure of phospholipid synthesis that was used in subsequent experiments. ex ...19705530011

homologous interference by incomplete sendai virus particles: changes in virus-specific ribonucleic acid synthesis.incomplete sendai virus particles (i particles) interfered with the replication of several strains of infectious sendai virions (standard virus) but not with the replication of newcastle disease virus, mumps virus, or sindbis virus. i particles did not induce interferon, and ultraviolet irradiation of i particles abolished their ability to interfere. protein synthesis was not necessary to establish interference. the degree of interference depended on the interval between exposure of cells to the ...19714331647
electrophoretic analysis of ribosomal and viral ribonucleic acids with a simple technique for slicing low-concentration polyacrylamide gels.the electrophoretic mobilities of ribosomal ribonucleic acids (rna) from cultured mammalian (hela, vero, mdbk), avian (chick embryo), and bacterial (escherichia coli) cells, and rna species extracted from selected viruses (sindbis, polio, tobacco mosaic, sendai) were compared, employing a simple, inexpensive technique for slicing low-concentration polyacrylamide gels. the procedure provides for rapid fractionation of gels used for characterization of rna, incorporating extrusion and serial secti ...19714331767

age-dependent resistance of mice to sindbis virus infection: viral replication as a function of host age.the development of resistance of outbred white mice to two plaque size variants of sindbis virus was studied as a function of host age. a sudden drop in mortality occurred over a 3-day period. as little as 1 plaque-forming unit (pfu) per mouse was lethal in 1-day-old animals, whereas inocula of 10(9) pfu per mouse failed to produce high mortality in weanlings. a comparison of viral growth kinetics shows that early replication was similar in newborns and weanlings but that after 6 to 8 hr the pro ...197116557964

selective association of sindbis virion proteins with different membrane fractions of infected cells.plasma and smooth membranes obtained from chicken embryo cells infected with sindbis virus were solubilized and subjected to electrophoresis on acrylamide gels. the electrophoretic patterns showed that (i) the major proteins synthesized and associated with plasma membranes from infected cells are virion proteins and (ii) at 4 hr after infection virion proteins are not present at detectable levels in the smooth membranes of the cell.19724337164
correlation of messenger rna function with adenylate-rich segments in the genomes of single-stranded rna viruses.oligonucleotides enriched in adenylate residues have been demonstrated in the genomes of two positive-strand rna viruses, sindbis and columbia sk. such oligonucleotides were not found in the genome of vesicular stomatitis virus, a negative-strand virus. the adenylate-rich oligonucleotides from sindbis and columbia sk viruses appeared similar when analyzed by zonal sedimentation in sucrose-sodium dodecyl sulfate.19724338595
