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

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

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

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

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.19715133729
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 ...19715289256

further changes in differentiation state accompanying the conversion of chinese hamster cells of fibroblastic form by dibutyryl adenosine cyclic 3':5'-monophosphate and hormones.the morphological conversion in vitro of chinese hamster ovary cells to a fibroblast form by a relatively large amount of dibutyryl adenosine cyclic 3':5'-monophosphate, or by a combination of small amounts of this compound and testosterone, is attended by appearance of the following additional properties: acquisition of strict contact inhibition of growth; reorientation of the random growth pattern into one in which cells grow parallel to their long dimension; disappearance of the randomly dist ...19714327009

ultraviolet light-induced division delayed in synchronized chinese hamster cells.the age-dependent, ultraviolet light (uvl) (254 nm)-induced division delay of surviving and nonsurviving chinese hamster cells was studied. the response was examined after uvl exposures adjusted to yield approximately the same survival levels at different stages of the cell cycle, 60% or 30% survival. cells irradiated in the middle of s suffered the longest division delay, and cells exposed in mitosis or in g(1) had about the same smaller delay in division. cells irradiated in g(2), however, wer ...19715106108

ultrastructure of the nucleolus during the chinese hamster cell cycle.changes in the structure of the nucleolus during the cell cycle of the chinese hamster cell in vitro were studied. quantitative electron microscopic techniques were used to establish the size and volume changes in nucleolar structures. in mitosis, nucleolar remnants, "persistent nucleoli," consisting predominantly of ribosome-like granular material, and a granular coating on the chromosomes were observed. persistent nucleoli were also observed in some daughter nuclei as they were leaving telopha ...19714933472

new class of purine mutants of chinese hamster ovary cells.mutants of chinese hamster ovary cells (cho/pro(-)) were isolated after mutagenesis with n-methylnitrosoguanidine and selection by the bromodeoxyuridine technique. six of these were mutants classified as purine-requiring. the metabolic block appears to be early in the purine biosynthetic pathway. the mutants do not appear to be genetically identical.19715547727

chromosomal aberrations and mortality of x-irradiated mammalian cells: emphasis on repair.chromosomal aberrations induced by x-rays in synchronized chinese hamster cells correlated well with mortality as the radiosensitivity was made to vary by a factor of 4 by treating the cells with colcemid or 5-bromodeoxyuridine and by irradiating the cells in different parts of the cell cycle. 37% survival was observed when the cells sustained about one aberration per cell. furthermore, the positive correlation was observed during repair of damage. repair was measured by the reduction in damage ...19715276778

deoxyribonucleic acid synthesis in ultraviolet-light-irradiated chinese hamster cells.two mammalian cell lines, chinese hamster ovary (cho) which can recover colony-forming ability between fractionated doses of ultraviolet light (uv), and chinese hamster b-14faf28 which cannot recover, were tested for the ability to bypass uv-induced photoproducts in dna during postirradiation dna synthesis. the molecular weight distributions of newly synthesized dna in uv-irradiated populations of both cell lines showed evidence for photoproduct bypass. hence, the bypass mechanism does not corre ...19715103274
