changes in deoxyribonucleic acid synthesis regulation in chinese hamster cells infected with simian virus 40.infection of primary or secondary cultures of chinese hamster embryo cells with simian virus 40 at a multiplicity of 20 to 50 induced synthesis of the virus-specific intranuclear t antigen in 80 to 90% of the cells within 48 to 72 hr. in the infected cultures, 30 to 50% more cells were recruited into deoxyribonucleic acid (dna) synthesis than in the controls, whether or not the cultures were confluent. the newly synthesized dna was mostly cellular, since little virus was produced (as shown by va ...19704322080

studies of dna-induced heritable alteration of mammalian intercellular interaction between mouse ehrlich ascites tumor and non-malignant chinese hamster cells occurred when these were co-cultured. that the intercellular processes which formed had emanated from the ea cells was revealed by immunofluoroscopy using anti-ea antiserum, and by direct microscopic examination. a passage of dna from the ea to the ch cells was also observed. on long-term co-culture, new cell forms arose which were isolated, cloned, and propagated. they showed a ch karyotype ...19704995321

replication of repetitious dna and the s period.the renaturation kinetics of labeled dna derived from synchronized chinese hamster cells indicate that the three classes of repetitious dna replicate uniformly throughout the s period, and that a piece of repetitious dna may occur at or near the beginning of each replicon. studies with mouse-cell dna suggest that mouse satellite dna replicates when euchromatin replicates.19705272325

chromosome pulverization in virus-induced heterokaryons of mammalian cells from different species.the phenomena of cell fusion and chromosome pulverization after inoculation with uv-inactivated sendai virus were studied in mixed suspensions of cell lines from different mammalian species. two cell combinations were used: the chinese hamster cell line (don) and rpmi 8226 (simpson) cell line of human hematopoietic origin,and the don and llc-mk2 (mk) cell lines, the latter derived from monkey kidney cells. each of the 3 cell lines had a high cell-fusion capacity when infected with the virus in h ...197018605421

regulation of initiation of dna synthesis in chinese hamster cells : ii. induction of dna synthesis and cell division by isoleucine and glutamine in g(1)-arrested cells in suspension culture.suspension cultures of chinese hamster cells (line cho), which had stopped dividing and were arrested in g(1) following growth to high cell concentrations in f-10 medium, could be induced to reinitiate dna synthesis and to divide in synchrony upon addition of the appropriate amounts of isoleucine and glutamine. both amino acids were required to initiate resumption of cell-cycle traverse. deficiencies in other amino acids contained in f-10 medium did not result in accumulation of cells in g(1), i ...197019866743

separation of nuclei representing different phases of the growth cycle from unsynchronized mammalian cell cultures.nuclei have been isolated from unsynchronized cultures of chinese hamster fibroblasts after varying intervals of growth following the incorporation of thymidine (-3)h for 20 min. these nuclei were fractionated by unit gravity sedimentation in a stabilizing density gradient of sucrose, and fractions were analyzed for the concentration of nuclei, dna, and radioactivity. a more rapidly sedimenting population of nuclei in the g(2) phase of the cell cycle was separated from a group of nuclei in the g ...19705513550

density invariance of cultured chinese hamster cells with stage of the mitotic cycle.isopycnic banding of chinese hamster line cho cells in ficoll gradients shows that a population in balanced, exponential growth is very homogeneous with respect to density, the coefficient of variation of the density distribution spectrum being less than 5% of the mean reduced density (i.e. density minus one). similar measurements on synchronized cultures indicate that reduced density varies by less than 2% around the life cycle. the mean density of cho cells in f-10 growth medium is calculated ...19705465290
regulation of initiation of dna synthesis in chinese hamster cells. i. production of stable, reversible g1-arrested populations in suspension culture.suspension cultures of chinese hamster cells (line cho) were grown to stationary phase (approximately 8-9 x 10(5) cells/ml) in f-10 medium. cells remained viable (95%) for at least 80 hr in stationary phase, and essentially all of the cells were in g(1) upon resuspension or dilution with fresh medium, the cells were induced to resume traverse of the life cycle in in synchrony, and the patterns of dna synthesis and division were similar to those observed in cultures prepared by mitotic selection. ...19705460461

radiosensitivity of mammalian cells. iv. effects of x-irradiation on the dna synthetic period in synchronized cells.the effect of x-irradiation on the timing of dna synthesis in the chinese hamster ovary cells has been investigated. mitotically synchronized cells irradiated in mitosis or early g(1) exhibited a fixed, dose-independent (150-2000 rad) delay of 1.6 hr in entry into s, while the duration of s was unaffected. cells irradiated during late g(1) or the first 0.8 hr of s were not affected either in time of initiation or duration of s. however, when cells 0.8 hr or more into s were irradiated, completio ...19705452354

two forms of repair of dna in mammalian cells following irradiation.when chinese hamster cells are lysed on top of an alkaline sucrose gradient, in time a fairly discrete dna-containing molecular species is released from an apparently more complex material. small doses of x-radiation speed the resolution of this complex while large doses degrade the material released from it. incubation after irradiation reverses both effects.19705461576

animal cells: noncorrelation of length of g1 phase with size after mitosis.the interval between mitosis and initiation of dna synthesis (g(1)) varied over a fourfold range for chinese hamster ovary cells, an established line. this was not because of size differences. synchlronous cells of different sizes began dna synthesis at similar times after mitosis. a novel technique of centrifugation for separating cells according to size is described.19705409485

cell sorting: automated separation of mammalian cells as a function of intracellular fluorescence.a system for high-speed sorting of fluorescent cells was able to sort mouse spleen cells from chinese hamster ovarian cells after development of fluorochromasia. highly fluorescent fractions separated after similar treatment from mouse spleen cells immunized to sheep erythrocytes were enriched in antibody-producing cells by factors of 4 to 10.19694898615
ribonucleic acid synthesis of vesicular stomatitis virus. i. species of ribonucleic acid found in chinese hamster ovary cells infected with plaque-forming and defective particles.plaque-forming b particles of vesicular stomatitis virus (vsv) induce the synthesis of virus-specific ribonucleic acid (rna) in chinese hamster ovary cells, whereas defective t particles do not. infection with low input multiplicities of b results in the formation of four species of rna. during infection with high multiplicities, rna synthesis begins with mainly these four species of rna but gradually shifts to a new pattern of rna synthesis involving five other species of rna. the change can al ...19694308915

temporal coordination of dna replication with enzyme synthesis in diploid and heteroploid cells.the rate of dna synthesis in the s phase of growth of synchronized diploid chinese hamster cells shows two maximums, while in heteroploid hamster cells the dna replication rate is constant. in diploid cells a reciprocal relationship exists between maximum dna synthetic rates and maximum lactate dyhydrogenase and thymidine kinase enzyme levels. enzyme activity in heteroploid cells increases continuously through the cell cycle with no evidence of oscillations. it seems possible that these differen ...196917655055
