| alteration of nucleoside transport of chinese hamster cells by dibutyryl adenosine 3':5'-cyclic monophosphate. | cultured chinese hamster ovary cells showed no significant change in generation time or fraction in the s-phase in the presence of 1 mm n(6),o(2')-dibutyryl adenosine 3':5'-cyclic monophosphate. growth continued for at least two generations after expression of the morphological transformation induced by this cyclic amp analog. despite identical growth rates, apparent rates of dna and rna synthesis (incorporation of [(3)h]-thymidine or [(3)h]uridine) were reduced up to 15-fold in log phase by 1 m ... | 1972 | 4345504 |

| mammalian cells with altered forms of rna polymerase ii. | mutants of chinese hamster ovary cells that are resistant to alpha-amanitin can be isolated. at least some of these mutants contain an altered form of dna-dependent rna polymerase ii, as indicated by its resistance to alpha-amanitin. these results indicate that mutation to alpha-amanitin resistance involves a change of a structural gene. | 1972 | 4508306 |

| 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 ... | 1972 | 5063839 |

| biological damage from intranuclear tritium: dna strand breaks and their repair. | isotopic decay in tritiated thymidine in the dna of frozen (-196 degrees c) chinese hamster cells causes breaks in dna strands to accumulate at a rate of 2.1 breaks per decay. after dna is thawed the tritium-induced breaks repair rapidly with a half-time of 15 minutes at 37 degrees c. in comparison to breakage by x-rays, the efficiency of dna strand breakage by tritium is equivalent to 0.48 rad per decay. this dose per decay is close to that predicted by simple dosimetric considerations (0.38 ra ... | 1972 | 5055946 |

| asparagine-requiring tumor cell lines and their non-requiring variants: cytogenetics, biochemistry and population dynamics. | asparagine-requiring jensen and walker rat tumor cells and their asparagine-independent variants have been analyzed. the following results were obtained: (1) both cell lines have very low levels of asparagine synthetase, and non-requiring revertants isolated from these lines have elevated levels of the enzyme. (2) no differences in chromosome number were detected between the parent jensen line and five jensen non-requiring revertants isolated from it. (3) both jensen and walker cells undergo asp ... | 1973 | 4798091 |

| regional localization of loci for human pgm and 6pgd on human chromosome one by use of hybrids of chinese hamster-human somatic cells. | the human gene loci phosphoglucomutase(1) (pgm(1), ec 2.7.5.1) and 6-phosphogluconate dehydrogenase (6pgd, ec 1.1.1.43), which are located on human chromosome one, have been assigned to a specific region of the short arm of that chromosome, by use of a hybrid cell line derived from a chinese hamster cell line deficient in hypoxanthine phosphoribosyl transferase and a strain of human diploid fibroblasts. cytogenetic analysis of a hybrid clone maintained for about 50 generations in vitro revealed ... | 1973 | 4517931 |

| mutations affecting the structure of hypoxanthine: guanine phosphoribosyltransferase in cultured chinese hamster cells. | 14 clones resistant to 8-azaguanine, isolated from mutagenically treated cultured cells from chinese hamsters, were tested for loss of enzymic and immunological activities of hypoxanthine: guanine phosphoribosyltransferase. three of the clones had no enzymic activity but reacted strongly with antiserum prepared against the enzyme (crm(+)), indicating the presence of a defective enzyme protein, probably caused by a mutation in its structural gene. the other 11 mutants had little or no enzymic or ... | 1973 | 4119786 |

| identification of chick chromosomes in cell hybrids formed between chick erythrocytes and adenine-requiring mutants of chinese hamster cells. | when chick erythrocytes were fused with adenine-requiring mutants of chinese hamster cells of two different complementation classes and grown in adenine-free medium for 1 week or longer, mitotic cells were observed containing both chick and chinese hamster metaphase chromosomes within a single cell. stable hybrid clones were subsequently isolated that possessed, in addition to a complete chinese hamster genome, a single specific chick chromosome. hybrids resulting from fusions involving differen ... | 1973 | 4517942 |

| isolation and characterization of revertants of the mammalian temperature sensitive leucyl-trna synthetase mutant tshl. | nine spontaneous and seven ethyl methanesulfonate induced revertants of the chinese hamster ovary cell line mutant (tshl), which possesses a temperature sensitive leucyl-trna synthetase, were isolated and characterized with respect to growth rate, leucyl-trna synthetase activity and thermolability, intracellular leucine pool size, and rrna content. although most revertants had increased leucyl-trna synthetase activity, and of those tested, all but one had increased thermostability, each appears ... | 1973 | 422661 |

| 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 ... | 1973 | 4795862 |

| 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 ... | 1973 | 4738102 |
