| 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 ... | 1970 | 5465290 |
| 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. ... | 1970 | 5460461 |

| 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 ... | 1970 | 5452354 |

| 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. | 1970 | 5461576 |

| 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. | 1970 | 5409485 |

| induction of nuclear envelopes around metaphase chromosomes after fusion with interphase cells. | the process of cellular fusion induced by sendai virus in chinese hamster cells (don line) afforded us the opportunity to study nuclear envelope formation around metaphase sets in the presence of interphase nuclei, when chromosome pulverization failed to occur in such multinucleate cells. morphologically, the enveloped metaphase chromosomes resembled a normal telophase nucleus, though minor differences prompted us to call it telophase-like. electron microscopic observations demonstrated that the ... | 1971 | 4329517 |

| genetics of somatic mammalian cells: lethal antigens as genetic markers for study of human linkage groups. | the antigen that causes killing of at least 98% of a human cell population treated with a 1% solution of a specific rabbit antiserum in the presence of complement is a sensitive genetic marker. the rapid loss of human chromosomes in human-chinese hamster cell hybrids makes possible a convenient test of linkage relationships with this marker. hybrid clones with and without the lethal antigen were isolated and analyzed. in 76 clones and subclones studied, 41 carried both the lethal antigen and the ... | 1971 | 4332008 |
| integration of simian virus 40 deoxyribonucleic acid into the deoxyribonucleic acid of primary infected chinese hamster cells. | simian virus 40 deoxyribonucleic acid (dna) became associated in an alkaline-stable form with the dna of chinese hamster embryo cells at 15 to 20 hr post-infection, at the time when cell dna synthesis and t antigen were induced. the integration process was not inhibited by d-arabinosyl cytosine and was only partially inhibited by cycloheximide. | 1971 | 4332141 |

| reinitiation within one cell cycle of the deoxyribonucleic acid synthesis induced by simian virus 40. | the infection of secondary cultures of chinese hamster cells with simian virus 40 (sv40) induces the appearance of cells with polyploid deoxyribonucleic acid (dna) content or chromosomal component within one cell generation. the mechanism of this phenomenon was studied by the use of 5-bromodeoxyuridine (budr) incorporation as a dna density marker. when cultures were treated with (14)c-budr and colcemide and harvested at 48 hr postinfection, only hybrid and light dna molecules were found in contr ... | 1971 | 4366428 |

| mammalian peptide chain termination. ii. codon specificity and gtpase activity of release factor. | in vitro peptide chain termination with release factor preparations from rabbit reticulocytes, guinea pig liver, or chinese hamster liver is directed with uaaa, uaga, or ugaa, suggesting that uaa, uag, and uga are terminator condons for mammalian cells. purified release factor from rabbit reticulocytes has ribosomaldependent gtpase activity, which is stimulated by uaaa. gtp hydrolysis appears requisite for in vitro peptide chain termination in mammals. | 1971 | 5276771 |

| nucleoli of diploid cell strains. thei normal ultrastructure and the effects of toyocamycin and actinomycin d. | nucleoli of cultured chinese hamster or mouse cells in early passages had a loosely reticular substructure. within the reticulum small, irregularly shaped, light fibrillar zones occurred which were contiguous with denser fibrillar zones. these denser zones appeared to be connected in some places to the particulate material which composed the mass of the nucleolus. generally, electron-transparent spaces separated the particulate zones from the fibrillar areas. treatment with toyocamycin, an agent ... | 1971 | 5104724 |
| distinctive characteristics of nucleoli of two established cell lines. | nucleoli of cultured cells of the established lines kb and l were found to possess a distinctive fine structural organization. the major portion of the nucleolar volume was composed of compact, particulate material. spheroidal fibrillar zones about 0.4 micro in diameter occurred within the particulate mass. these fibrillar zones had a central light area and a denser rim. toyocamycin treatment, which sharply inhibited the appearance of newly synthesized rna in the cytoplasm, caused the gradual di ... | 1971 | 5104725 |

| sedimentation of dna released from chinese hamster cells. | under high ph and high salt conditions, chinese hamster cells lyse and release a dna-containing material of large molecular weight. with increasing lysis time, a smaller material is resolved from the large one. relative to t4 dna, the smaller is estimated to be approximately 2 x 10(8) daltons (number average). from a comparison of radiation data, the target size of the larger is about 15 times that of the smaller (probably a lower limit estimate). in addition to concentration of alkali, temperat ... | 1971 | 4997648 |
| ultrastructural analysis of mitotic spindle elongation in mammalian cells in vitro. direct microtubule counts. | the mitotic spindle of many mammalian cells undergoes an abrupt elongation at anaphase. in both cultured rat kangaroo (strain ptk(1)) and chinese hamster (strain don-c) fibroblasts, the distance from pole to pole at metaphase doubles during anaphase and telophase. in order to determine the organization and distribution of spindle microtubules during the elongation process, cells were fixed and flat embedded in epon 812. selected cells were photographed with the phase-contrast microscope and then ... | 1971 | 4939523 |

| spatial distribution of biological effect n a 3.9-gev nitrogen ion beam. | a beam of nitrogen ions obtained with the princeton particle accelerator was used for the irradiation of chinese hamster (m3-1) cells in monolayer culture. the 3.9-billion-electron-volt (gev) beam passed along the monolayer, so that ions were stopped in the culture. a sharply defined zone of extensive cell destruction occurred in the last centimeter of the beam path. | 1971 | 5133729 |
| mutagenicity to mammalian cells of epoxides and other derivatives of polycyclic hydrocarbons. | the cytotoxicity and mutagenicity of several polycyclic hydrocarbons and their k-region derivatives were tested in a clone of chinese hamster cells; the production of clones resistant to 8-azaguanine was used as the marker for mutagenesis. in the series related to benz(a)anthracene, the k-region epoxide was highly mutagenic, and the phenol was less mutagenic; the hydrocarbon and cis and trans-dihydrodiols were not mutagenic. seven resistant clones were isolated and retained their drug-resistance ... | 1971 | 5289256 |
