damage and repair of dna in 5-bromodeoxyuridine-labeled chinese hamster cells exposed to fluorescent light.illumination of chinese hamster cells with fluorescent light after 5-bromodeoxyuridine incorporation leads to extensive single-strand breakage in the dna of the exposed cells. the rate of production of single-strand breaks is dependent on the extent to which thymine is replaced by 5-bromouracil. at least some of the breaks observed with alkaline gradients are probably produced in vivo and are probably not contingent upon alkaline hydrolysis since breakage can be demonstrated with neutral gradien ...19725063839

induced changes in the rates of uridine- 3 h uptake and incorporation during the g 1 and s periods of synchronized chinese hamster cells.the rates of uridine-5-(3)h incorporation into rna and the rates of uridine uptake into the acid-soluble pool during the cell cycle of v79 chinese hamster cells were examined. cells cultured on eagle's minimal essential medium supplemented with fetal calf serum, lactalbumin hydrolysate, glutamine, and trypsin displayed rates of incorporation and uptake which increased only slightly during g(1) and accelerated sharply as dna synthesis commenced. in contrast, cells cultured on minimal essential me ...19725009516

chromosome pulverization in micronuclei induced by tritiated thymidine.cultures of a pseudodiploid cell line (don) of chinese hamster origin were exposed to varying doses of tritiated thymidine (tdr-(3)h) for relatively long periods of time. in addition to previously observed chromosomal aberrations) such as breaks and reunions, a substantial number of interphasic cells with micronuclei and of metaphases associated with pulverized chromosomes was found; both phenomena were dependent on exposure time to and concentration of tdr-(3)h. the former phenomenon appeared t ...19725061680

mutagenicity and carcinogenicity of n-methyl-n'-nitro-n-nitrosoguanidine i. induction of chromosome aberrations and mitotic anomalies in chinese hamster ovary cells.cultured chinese hamster ovary (cho) cells were exposed to different concentrations of n-methyl-n'-nitro-n-nitrosoguanidine (mnng) for either 24 hr or 6 days. for cytological consequences of mnng exposure, cho cells were treated for 24 hr and allowed a 24 hr recovery period prior to analysis; for the estimation of cytotoxicity of mnng, cells were treated for 6 days followed by a 6 day recovery period. the cytotoxic effect of mnng based on the colony-forming ability of treated cells showed a semi ...1973422929

derivation of tk- clones from revertant tk+ mammalian cells.in order to obtain a large collection of chinese hamster cell clones defective in thymidine kinase (tk(-)), brdu(r) selection experiments have been performed on wild-type and revertant tk(+) cell lines. no clones (< 10(-9)) were obtained from the wild-type tk(+) cell line by single-step selection. in contrast, revertant tk(+) clones readily gave rise to stable tk(-) derivatives (1 - 2 x 10(-4)). both wild-type and revertant tk(+) clones spontaneously yielded 8-ag(r) colonies with the same freque ...19734359755

contrast between the environmental ph dependencies of prophasing and nuclear membrane formation in interphase-metaphase cells.in chinese hamster don cells, fusion of an interphase cell with a metaphase cell resulted either in prophasing of the interphase nucleus, including loss of the nuclear envelope (ne), or in the formation of a double membrane around the metaphase chromosomes. only one of these phenomena occurred in a given interphase-metaphase (i-m) binucleate cell. at ph 7.4, there was about an equal probability that either event could occur amongst the population of i-m cells. the effect of ph changes in the med ...19734795862

synchronization of mitochondrial dna synthesis in chinese hamster cells (line cho) deprived of isoleucine.mitochondrial dna (mit-dna) synthesis was compared in suspension cultures of chinese hamster cells (line cho) whose cell cycle events had been synchronized by isoleucine deprivation or mitotic selection. at hourly intervals during cell cycle progression, synchronized cells were exposed to tritiated thymidine ([(3)h]tdr), homogenized, and nuclei and mitochondria isolated by differential centrifugation. mit-dna and nuclear dna were isolated and incorporation of radioisotope measured as counts per ...19734738104
further characterization of the f1-histone phosphokinase of metaphase-arrested animal cells.exponentially growing chinese hamster cells are found to contain two major phosphokinase activities with specificity for the phosphorylation of f1 (lysine-rich) histone. these two activities, designated ki and kii, were extracted with 0.35 m nacl and fractionated in 0.2 m nacl by sephadex g-200 gel filtration. ki, which is similar to the ubiquitous cyclic 3',5'-adenosine monophosphate (camp)-dependent phosphokinase, differs from kii by several criteria. kii is mol wt 90,000, camp independent, ra ...19734738102

changes in surface morphology of chinese hamster ovary cells during the cell cycle.synchronized populations of chinese hamster ovary (cho) cells in confluent culture have been examined by scanning electron microscopy and their surface changes noted as the cells progress through the cycle. during g(1) it is characteristic for cells to show large numbers of microvilli, blebs, and ruffles. except for the ruffles, these tend to diminish in prominence during s and the cells become relatively smooth as they spread thinly over the substrate. during g(2) microvilli increase in number ...19734735453
