Capecchi, Mario R. | Location and function of retroviral and SV40 sequences that enhance biochemical transformation after microinjection of DNA. | Biochemical transformation of thymidine-kinase-deficient (TK-) mouse L cells is enhanced 20 to 40 fold when microinjected plasmid DNA contains regions of the genomes of Rous sarcoma virus or simian virus 40 in addition to the complete herpes simplex virus tk gene, irrespective of the orientation and... | Animals; Base Sequence; Genes, Viral; Plasmids; Thymidine Kinase | 1983-07-01 |

Capecchi, Mario R. | Hoxc13 mutant mice lack external hair | Hox genes are usually expressed temporally and spatially in a colinear manner with respect to their positions in the Hox complex. Consistent with the expected pattern for a paralogous group 13 member, early embryonic Hoxc13 expression is found in the nails and tail. Hoxc13 is also expressed in vibri... | Filiform papillae; Homozygotes; Paralogous | 1998-01-01 |

Coffin, Cheryl M.; Capecchi, Mario R. | Alveolar rhabdomyosarcomas in conditional Pax3:Fkhr mice: cooperativity of Ink4a/ARF and Trp53 loss of function. | Alveolar rhabdomyosarcoma is an aggressive childhood muscle cancer for which outcomes are poor when the disease is advanced. Although well-developed mouse models exist for embryonal and pleomorphic rhabdomyosarcomas, neither a spontaneous nor a transgenic mouse model of alveolar rhabdomyosarcoma has... | Cell Differentiation; Forkhead Transcription Factors; Myogenic Regulatory Factors | 2004-11-01 |

Jorgensen, Erik | Mutations in β-spectrin disrupt axon outgrowth and sarcomere structure | B-Spectrin is a major component of the membrane skeleton, a structure found at the plasma membrane of most animal cells. B-Spectrin and the membrane skeleton have been proposed to stabilize cell membranes, generate cell polarity, or localize specific membrane proteins. We demonstrate that the Caen... | | 2000 |

Davidson, Diane W. | Granivory in the Chihuahuan Desert: interactions within and between trophic levels | We investigated the effects of Chihuahuan Desert granivores on three seasonal classes of plant resource species, the effects of these resource classes on one another, and the ways in which interactions through plant resources affect the abundances of seed consumers. At our study site, three seasona... | Annual plant; Ant; Competition; Community; Desert; Ecosystem structure; Experiment; Granivore; Indirect interaction; Rodent; Population cycles; Seed predation | 1985 |

Beckerle, Mary C. | Targeting of zyxin to sites of actin membrane interaction and to the nucleus | The localization of proteins to particular intracellular compartments often regulates their functions. Zyxin is a LIM protein found prominently at sites of cell adhesion, faintly in leading lamellipodia, and transiently in cell nuclei. Here we have performed a domain analysis to identify regions in ... | Zyxin; Actin; LIM domains; Focal adhesions; Lamellipodia; Cytoskeletal architecture | 2001 |

Beckerle, Mary C. | CRP1, a LIM domain protein implicated in muscle differentiation, interacts with α-actinin | Members of the cysteine-rich protein (CRP) family are LIM domain proteins that have been implicated in muscle differentiation. One strategy for defining the mechanism by which CRPs potentiate myogenesis is to characterize the repertoire of CRP binding partners. | CRP1; Cysteine-rich proteins; Actinin; Protein-protein interactions; LIM domains | 1997 |

Beckerle, Mary C. | Muscle LIM proteins are associated with muscle sarcomeres and require dMEF2 for their expression during Drosophila myogenesis | A genetic hierarchy of interactions, involving myogenic regulatory factors of the MyoD and myocyte enhancer-binding 2 (MEF2) families, serves to elaborate and maintain the differentiated muscle phenotype through transcriptional regulation of muscle-specific target genes. | LIM domains; Cysteine-rich proteins | 1999 |

Olivera, Baldomero M.; McIntosh, J. Michael; Hillyard, David R. | A-superfamily of conotoxins: structural and functional divergence | The generation of functional novelty in proteins encoded by a gene superfamily is seldom well documented. In this report, we define the A-conotoxin superfamily, which is widely expressed in venoms of the predatory cone snails (Conus), and show how gene products that diverge considerably in stru... | Conotoxins; A-superfamily conotoxin | 2004-02-03 |

Olivera, Baldomero M. | T-superfamily of conotoxins | We report the discovery and initial characterization of the T-superfamily of conotoxins. Eight different T-superfamily peptides from five Conus species were identified; they share a consensus signal sequence, and a conserved arrangement of cysteine residues (- -CC- -CC-). T-superfamily peptides... | Conotoxins; T-superfamily | 1999 |

Bastiani, Michael | Developmental expression of REGA-1, a regionally expressed glial antigen in the central nervous system of grasshopper embryos | Glial cells are a large component of the developing nervous system, appearing before the onset of axon outgrowth in a variety of developing systems. Their time of appearance and their location in conjunction with developing axon pathways may allow them to define the position of axon pathways. | Antibody; Axons; Pathways | 1991 |

Coley, Phyllis D. | Between-species differences in leaf defenses of tropical trees | Rates of herbivory and patterns of leaf defense are presented for light-demanding and shade-tolerant tree species growing in a lowland rainforest in Panama. More than 85 percent of the annual leaf damage is due to grazing by insects. There are over three orders of magnitude difference between specie... | Herbivory; Interspecific variation; Panama; Growth rate; Shade tolerance; Treefall gaps; Tropical forest; Understory; Tannins; Alkaloids | 1987 |

Sperry, John S. | Evaluation of Murray's law in Psilotum nudum (Psilotaceae), an analogue of ancestral vascular plants | Previous work has shown that the xylem of seed plants follows Murray's law when conduits do not provide structural support to the plant. Here, compliance with Murray's law was tested in the stem photosynthesizer Psilotum nudum, a seedless vascular plant. Psilotum nudum was chosen because the central... | Conduit furcation number; hydraulic architecture; Murray's law | 2005 |

Adler, Frederick R. | Sputum biomarkers and the prediction of clinical outcomes in patients with cystic fibrosis | Lung function, acute pulmonary exacerbations (APE), and weight are the best clinical predictors of survival in cystic fibrosis (CF); however, underlying mechanisms are incompletely understood. Biomarkers of current disease state predictive of future outcomes might identify mechanisms and provide tre... | | 2012-01-01 |

Gesteland, Raymond F.; Atkins, John F.; Felden, Brice; McCutcheon, John P. | Probing the structure of the Escherichia coli 10Sa RNA (tmRNA) | The conformation of the Escherichia coli 10Sa RNA (tmRNA) in solution was investigated using chemical and enzymatic probes. Single- and double-stranded domains were identified by hydrolysis of tmRNA in imidazole buffer and by lead(II)-induced cleavages. Ribonucleases T1 and S1 were used to map unpai... | Covariation; Pseudoknot; Structural Probing; 10Sa RNA; tmRNA | 1997 |

Thomas, Kirk R.; Capecchi, Mario R. | Efficient correction of mismatched bases in plasmid heteroduplexes injected into cultured mammalian cell nuclei. | Heteroduplexes were prepared from two plasmids, pRH4-14/TK and pRH5-8/TK, containing different amber mutations in the neomycin resistance gene (Neor). The Neor gene was engineered to be expressed in both bacterial and mammalian cells. A functional Neor gene conferred kanamycin resistance to bacteria... | Cell Nucleus; Cells, Cultured; Microinjections | 1985-01 |

Sperry, John S. | Embolized conduits of rice (Oryza sativa, poaceae) refill despite negative xylem pressure | Embolism reversal in rice plants was studied by testing the plant's ability to refill embolized conduits while xylem pressures were substantially negative. Intact, potted plants were water-stressed to a xylem pressure of -1.88 + 0.1 MPa and a 66.3 + 3.8% loss of xylem conductivity (PLC) by cavitatio... | Embolism; novel revilling; Oryza | 2005 |

Davidson, Diane W. | Granivory in a desert ecosystem: experimental evidence for indirect facilitation of ants by rodents | Two major groups of desert granivores, ants and rodents, coexist as permanent residents of local desert habitats in southwestern North America. At our Sonoran Desert study site, both of the major taxa exhibited short-term increase in density when the other taxon was experimentally removed.

Davidson, Diane W. | Dispersal adaptations of some acacia species in the Australian arid zone | Most Australian representatives of the genus Acacia have diaspores with arillate appendages indicative of adaptation for active dispersal by animals.
