| 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 |

| 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 |

| 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 |

| 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 |

| comparative analysis of mammalian sperm motility. | spermatozoa of several mammalian species were studied by means of high-speed cinematography and electron microscopy. three types of motile patterns were observed in mouse spermatozoa. the first type involved an asymmetrical beat which seemed to propel the sperm in circular paths. the second type involved rotation of the sperm and appeared to allow them to maintain straight paths. in the third type of pattern, the sperm appeared to move by crawling on surfaces in a snakelike manner. spermatozoa o ... | 1972 | 5025110 |

| repopulation of the postmitotic nucleolus by preformed rna. | this study is concerned with the fate of the nucleolar contents, particularly nucleolar rna, during mitosis mitotic cells harvested from monolayer cultures of chinese hamster embryonal cells, kb6 (human) cells, or l929 (mouse) cells were allowed to proceed into interphase in the presence or absence (control) of 0.04-0 08 microg/ml of actinomycin d, a concentration which preferentially inhibits nucleolar (ribosomal) rna synthesis 3 hr after mitosis, control cells had large, irregularly shaped nuc ... | 1972 | 4112854 |
| loss of simian virus 40 dna-rna hybrids from nitrocellulose membranes; implications for the study of virus--host dna interactions. | complete hybrids of simian virus 40 (sv40)dna and its complementary rna (crna) are not retained on nitrocellulose membranes. at saturating crna concentrations, retention of the hybrids indicates incomplete homology between dna and rna, probably due to incorporation of host dna in the viral dna; this effect is most pronounced when dna is produced in cells infected at high multiplicity. hybrids between dna of chinese hamster cells transformed by sv40 and crna are retained if the dna fragments are ... | 1972 | 4340749 |
| translation of reovirus messenger rnas synthetesized in vitro into reovirus polypeptides by several mammalian cell-free extracts. | single-stranded reovirus rna, synthesized in vitro by reovirus cores, functioned as messenger rna in cell-free extracts prepared from several mammalian cells: krebs ii mouse ascites cells, mouse l cells, chinese hamster ovary cells, hela cells, and rabbit reticulocytes. as shown by acrylamide gel electrophoresis, all eight polypeptides known to be specified by reovirus were synthesized in the reticulocyte system. in the other extracts, from 5 to 7 complete virus proteins were made. | 1972 | 4506788 |
| genetics of somatic mammalian cells: demonstration of a human esterase activator gene linked to the adeb gene. | prototrophic hybrids formed from an adenine-requiring chinese hamster cell and human fibroblasts uniformly display new esterase activity that differs from that of either parental cell in electrophoretic mobility and substrate specificity. the hybrids that grew in the selective medium and possessed the new esterase activity had a single extra chromosome that resembled a b-group human chromosome. when clones of such hybrid cells were cultured in nonselective medium, they rapidly reverted to inabil ... | 1972 | 4508320 |

| tumor etiology and chromosome pattern. | fibrosarcomas induced in chinese hamsters and rats by rous sarcomla virus and 7,12-dimethylbenz(a)anthracene are associated with nonrandom chromosome variation. although histologically indistinguishable, the tumors induced by the virus or chemical in each host species are characterized by completely different karyotypic patterns. | 1972 | 4338345 |
| ribonucleic acid synthesis of vesicular stomatitis virus. iv. transcription by standard virus in the presence of defective interfering particles. | exposure of vesicular stomatitis virus-infected chinese hamster ovary cells to cycloheximide results in the complete transcription of virion ribonucleic acid (rna) into only 28s and 13 to 15s viral-specific rna species. these rna are identical to viral messenger rna by the following criteria: size, single-strandedness, complementarity to virion rna, and formation of messenger ribonucleoproteins. this transcription represents the intracellular enzymatic activity of the virion-associated polymeras ... | 1972 | 4338638 |

| induction of auxotrophic mutations by treatment of chinese hamster cells with 5-bromodeoxyuridine and black light. | treatment of an aneuploid chinese hamster cell line (v79) in tissue culture with 5-bromodeoxyuridine and black light, with or without prior exposure of cells to another mutagen, led to the isolation of auxotrophic mutants, each of which exhibits a specific nutritional requirement for glycine, uridine, purine, or for a combination of glycine, hypoxanthine, and thymidine. 61 mutants that could not use exogenous galactose were also isolated. thus, this treatment functions as an inductive, but not a ... | 1972 | 4508333 |

| 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 |
