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.

Adler, Frederick R. | Role of heterogeneity in the persistence and prevalence of sin nombre virus in deer mice | Many diseases persist at a relatively low prevalence, seemingly close to extinction. For a chronic disease in a homogeneous population, reducing the transmission rate by a fraction proportional to the prevalence would be sufficient to eradicate the disease. This study examines how higher prevalence ... | Transmission; Survivorship; Seropositivity | 2008 |

Ehleringer, James R. | Carbon isotope discrimination and water relations of oak hybrid populations in southwestern Utah | The evergreen oak Quercus turbinella and the deciduous Q. gambelii form natural hybrids in southwestern Utah and northern Arizona. Hybrid individuals also are found in northern Utah in a region where only Q. gambelii currently exists, indicating that Q. turbinella has recently retreated southward. ... | Quercus turbinella; Oak hybrids; Leaf structure; Leaf nitrogen; Carbon isotope discrimination; Water potential; Oak ecology | 2000 |

Beckerle, Mary C. | Comparison of three members of the cysteine-rich protein family reveals functional conservation and divergent patterns of gene expression | Members of the cysteine-rich protein (CRP) family are evolutionarily conserved proteins that have been implicated in the processes of cell proliferation and differentiation.

Ehleringer, James R. | Intra- and interspecific variation for summer precipitation use in pinyon-juniper woodlands | In the arid southwest of North America, winter precipitation penetrates to deep soil layers, whereas summer"monsoon" precipitation generally wets only surface layers. Use of these spatially separated water sources was determined for three dominant tree species of the pinyon-juniper ecosystem at six ... | D/H ratios; Juniperus osteosperma; Pinus edulis; pinyon-juniper ecosystem; plant water sources; precipitation use; Quercus gambelii; roots; Photosynthetic gas exchange; Monsoon | 2000 |

Voth, Gregory Alan; Ayton, Gary S. | Role of protein interactions in defining HIV-1 viral capsid shape and stability: a coarse-grained analysis | Coarse-grained models of the HIV-1 CA dimer are constructed based on all-atom molecular dynamics simulations. Coarse-grained representations of the capsid shell, which is composed of approximately 1,500 copies of CA proteins, are constructed and their stability is examined.

Beckerle, Mary C. | Nuclear-cytoplasmic shuttling of the focal contact protein, zyxin: a potential mechanism for communication between sites of cell adhesion and the nucleus | Integrin-dependent cell adhesion to specific extracellular matrix molecules has been demonstrated to trigger dramatic changes in gene expression that can affect cell fate. However, little is understood about the molecular mechanism by which events at sites of cell-substratum adhesion are communicate... | Zyxin; Cytosol; Nuclear export signal | 1997 |

Sperry, John S. | Cavitation fatigue - the weakening of cavitation resistance of xylem and its reversibility | Xylem function is essential for the growth and survival of higher land plants.

Capecchi, Mario R. | Gene targeting: an historical perspective | Our entry into what was going to become the field of gene targeting began in 1977. I was experimenting with the use of extremely small glass needles to inject DNA directly into the nuclei of living cells.

Adler, Frederick R.; Carrier, David R. | Interaction between the X chromosome and an autosome regulates size sexual dimorphism in Portuguese Water Dogs | Size sexual dimorphism occurs in almost all mammals.
