Blair, David F. | Chemical and spectroscopic evidence for the formation of a ferryl Fea3 intermediate during turnover of cytochrome c oxidase | When partially reduced cytochrome c oxidase samples are reoxidized with dioxygen, an EPR-silent dioxygen intermediate, which is at the three-electron level of dioxygen reduction, is trapped at the dioxygen reduction site. The intermediate has novel spectral features at 580 and 537 nm. Combined op... | Cytochrome c oxidase; EPR; Fea3 intermediate; Reduction | 1986 |

Hultine, Kevin | Carbon and nitrogen allocation to male and female reproduction in Rocky Mountain Douglas-fir (Pseudotsuga menziesii var. glauca, Pinaceae) | We measured carbon (respiration, photosynthesis, and production) and nitrogen allocation to male and female cones of Rocky Mountain Douglas-fir (Pseudotsuga menziesii var. glauca) to quantify gender-specific: (1) resource allocation to reproduction, and (2) contribution to carbon costs of reproducti... | Gender; photosynthesis; resource allocation | 2000 |

Capecchi, Mario R. | Hox genes and mammalian development | We have examined the interactions of Hox genes in forming a cervical vertebrae, hindbrain, and limbs. In each case, it is apparent that individual Hox genes are performing individual functions but that more profound roles are apparent when they act in combination with others Hox genes. The observed ... | Drosophila; Gene Expression Regulation, Developmental; Homozygote | 1997 |

Gussin, Gary N.; Capecchi, Mario R. | Protein synthesis directed by DNA phage messengers. | Even through the amino acids corresponding to most of the 64 nucleotide triplets are now known, several important aspects of the genetic code are not yet fully understood. In particular we need more knowledge about the "punctuation marks" of the code-for example, the signals necessary for the initia... | Carbon Isotopes; Escherichia coli; Genetic Code; Methionine | 1967-09-01 |

Jorgensen, Erik; Schuske, Kimberly R. | CAPS and syntaxin dock dense core vesicles to the plasma membrane in neurons | Docking to the plasma membrane prepares vesicles for rapid release. Here, we describe a mechanism for dense core vesicle docking in neurons. In Caenorhabditis elegons motor neurons, dense core vesicles dock at the plasma membrane but are excluded from active zones at synapses. | | 2008 |

Olivera, Baldomero M. | Poly(ADP-ribosylation) of DNA topoisomerase I from calf thymus | We demonstrate that the activity of the major DNA topoisomerase I from calf thymus is severely inhibited after modification by purified poly(ADP-ribose) synthetase. Polymeric chains of poly(ADP-ribose) are covalently attached to DNA topoisomerase I. These observations with highly purified enzymes ... | ADP-ribosylation; Poly(ADP-ribose) synthetase | 1984 |

Adler, Frederick R. | Mathematical modeling the age dependence of Epstein-Barr virus associated infectious mononucleosis | Most people get Epstein-Barr virus (EBV) infection at young age and are asymptomatic. Primary EBV infection in adolescents and young adults however, often leads to infectious mononucleosis (IM) with symptoms including fever, fatigue, and sore throat that can persist for months. Expansion in the numb... | | 2011 |

Capecchi, Mario R. | Absence of radius and ulna in mice lacking hoxa-11 and hoxd-11. | Mice with targeted disruptions in Hox genes have been generated to evaluate the role of the Hox complex in determining the mammalian body plan. This complex of 38 genes encodes transcription factors that specify regional information along the embryonic axes. Early in vertebrate evolution an ancestra... | Alleles; Animals; Bone and Bones; Carpal Bones | 2003-09-02 |

Moon, Ann M.; Capecchi, Mario R. | Fgf8 is required for outgrowth and patterning of the limbs. | The expression pattern and activity of fibroblast growth factor-8 (FGF8) in experimental assays indicate that it has important roles in limb development, but early embryonic lethality resulting from mutation of Fgf8 in the germ line of mice has prevented direct assessment of these roles. Here we rep... | Animals; Body Patterning; Bone Morphogenetic Proteins; Ectoderm | 2000-12-26 |

Bohs, Lynn A. | Solanum phylogeny inferred from chloroplast DNA sequence data | A data set derived from gene sequences of ndhF is used to deduce phylogenetic relationships among the subgenera of Solanum, among related genera of the tribe Solaneae, and within selected Solanum clades. Complete ndhF sequences were obtained for 12 species o f Solanum, representing five of the seve... | Solanum; Capsicum; Cyphomandra; Lycopersicon; Datura; Jaltomata; Nicotiana; Physalis; ndhF; Chloroplast DNA | 1999 |

Capecchi, Mario R. | Hox10 and Hox11 genes are required to globally pattern the mammalian skeleton. | Mice in which all members of the Hox10 or Hox11 paralogous group are disrupted provide evidence that these Hox genes are involved in global patterning of the axial and appendicular skeleton. In the absence of Hox10 function, no lumbar vertebrae are formed. Instead, ribs project from all posterior ve... | Alleles; Animals; Forelimb; Gene Expression Regulation, Developmental; Hindlimb | 2003-07-18 |

Sperry, John S. | Evolution of water transport and xylem structure | Land plants need water to replace the evaporation that occurs while atmospheric CO2 is diffusing into photosynthetic tissue. The water-for-carbon exchange rate is poor, and evolutionary history indicates a progression of innovations for cheap water transport--beginning in order with capillary sucti... | Cavitation; Vessels; Plants | 2003 |

Crespo, Jose Guillermo | Dislodgement effect of natural semiochemicals released by disturbed triatomines: a possible alternative monitoring tool | The quick detection of domestic and peridomestic triatomines in their environments becomes difficult without the use of dislodgement substances that flush them out from their shelters. At present, tetramethrin 0.2% is being widely used in control programs. Although it is an efficient dislodging agen... | | 2013-01-01 |

Hansen, Mark S.; Healy, Lindsey J.; Johnson, Christopher R.; Capecchi, Mario R.; Keller, Charles; Jones, Greg M. | Virtual histology of transgenic mouse embryos for high-throughput phenotyping. | A bold new effort to disrupt every gene in the mouse genome necessitates systematic, interdisciplinary approaches to analyzing patterning defects in the mouse embryo. We present a novel, rapid, and inexpensive method for obtaining high-resolution virtual histology for phenotypic assessment of mouse ... | Forkhead Transcription Factors; Paired Box Transcription Factors | 2006 |

Clayton, Dale H. | Reciprocal natural selection on host-parasite phenotypes | Coevolution is evolution in one species in response to selection imposed by a second species, followed by evolution in the second species in response to reciprocal selection imposed by the first species. Although reciprocal selection is a prerequisite of coevolution, it has seldom been documented in... | Host-parasite phenotypes; Ectoparasites; Virulence; Fitness | 1999 |

Capecchi, Mario R. | Targeted mutations in hoxa-9 and hoxb-9 reveal synergistic interactions. | Mice were generated with a targeted disruption of the homeobox-containing gene hoxb-9. Mice homozygous for this mutation show defects in the development of the first and second ribs. In most cases the first and second ribs are fused near the point at which the first and second pairs of ribs normally... | Embryonic and Fetal Development; In Situ Hybridization; Mice, Knockout | 1997-01-15 |

Adler, Frederick R. | Alternating host cell tropism shapes the persistence, evolution and coexistence of Epstein-Barr virus infections in human | Epstein-Barr virus (EBV) infects and can persist in a majority of people worldwide. Within an infected host, EBV targets two major cell types, B cells and epithelial cells, and viruses emerging from one cell type preferentially infect the other. We use mathematical models to understand why EBV infec... | | 2011 |

Moon, Ann M.; Capecchi, Mario R. | Roles of Fgf4 and Fgf8 in limb bud initiation and outgrowth. | Although numerous molecules required for limb bud formation have recently been identified, the molecular pathways that initiate this process and ensure that limb formation occurs at specific axial positions have yet to be fully elucidated.

Jorgensen, Erik | μ2 adaptin facilitates but is not essential for synaptic vesicle recycling in Caenorhabditis elegans | Synaptic vesicles must be recycled to sustain neurotransmission, in large part via clathrin-mediated endocytosis.
