Hughes, Kelly T.; Chevance, Fabienne | Mechanism of outer membrane penetration by the eubacterial flagellum and implications for spirochete evolution | The rod component of the bacterial flagellum polymerizes from the inner membrane across the periplasmic space and stops at a length of 25 nm at the outer membrane. Bushing structures, the P- and L-rings, polymerize around the distal rod and form a pore in the outer membrane. The flagellar hook stru... | Flagellar assembly; Spirochete evolution; Membrane penetration | 2007 |

Beckerle, Mary C. | Members of the zyxin family of LIM proteins interact with members of the p130cas family of signal transducers | Integrin binding to extracellular matrix proteins induces formation of signaling complexes at focal adhesions. Zyxin co-localizes with integrins at sites of cellsubstratum adhesion and is postulated to serve as a docking site for the assembly of multimeric protein complexes involved in regulating ce... | Zyxin; Actin; LIM domains; Trip6; Focal adhesions | 2002 |

Potts, Wayne K. | MHC signaling during social communication | The major histocompatibility complex (MHC) has been known to play a critical role in immune recognition since the 1950s. It was a surprise, then, in the 1970s when the first report appeared indicating MHC might also function in social signaling. Since this seminal discovery, MHC signaling has been f... | 2012-01-01 | |

Capecchi, Mario R. | Mice lacking endothelial ACE: normal blood pressure with elevated angiotensin II | Recently, the concept of local renin-angiotensin systems (RAS) capable of generating angiotensin II apart from the circulation has received considerable attention. To investigate this, we generated ACE 1/3 mice in which one allele of ACE is null and the second allele was engineered to express ACE o... | 2003 | |

Capecchi, Mario R. | Mice lacking endothelial angiotensin-converting enzyme have a normal blood pressure | To test the hypothesis that local vascular production of angiotensin II is necessary for the normal regulation of blood pressure, we engineered a new line of genetically altered mice that lack endothelial angiotensin-converting enzyme (ACE). This was accomplished using a novel strategy of targeted... | 2002 | |

Capecchi, Mario R. | Mice with cardiac-restricted angiotensin-converting enzyme (ACE) have atrial enlargement, cardiac arrhythmia, and sudden death | To investigate the local effects of angiotensin II on the heart, we created a mouse model with 100-fold normal cardiac angiotensin-converting enzyme (ACE), but no ACE expression in kidney or vascular endothelium. This was achieved by placing the endogenous ACE gene under the control of the α-myo... | Atrial enlargement; Cardiac arrhythmia; ACE | 2004 |

Capecchi, Mario R. | Mice with enhanced macrophage angiotensin-converting enzyme are resistant to melanoma | Angiotensin-converting enzyne (ACE) is a pepitdase responsible for the cleavage of angiotensin I and Several other peptides. Here, gene targeting was used to switch control of the ACE locus from the endogenous promoter to the macrophage-specific c-fms promoter. Challenge of these mice, called ACE 10... | Macrophage enzyme; Melanoma resistance; Enhanced macrophage angiotensin-converting enzyme | 2007 |

Capecchi, Mario R. | Mice with targeted disruptions in the paralogous genes hoxa-3 and hoxd-3 reveal synergistic interactions. | The Hox genes encode transcription factors which mediate the formation of the mammalian body plan along the anteroposterior and appendicular axes. Paralogous Hox genes within the separate linkage groups are closely related with respect to DNA sequence and expression, suggesting that they could have ... | Animals; Atlas; Homozygote; Mice; Models, Genetic | 1994-07-28 |

Davidson, Diane W. | Microtopography of microbiotic crusts on the Colorado Plateau, and distribution of component organisms | We analyzed the microtopography of microbiotic soil crusts at 3 sites on the Colorado Plateau of southern Utah and investigated distributions of cyanobacteria and several lichens in distinctive microhabitats created by this topography. At all 3 sites the long axes of linear soil mounds were oriented... | Microtopography; Microbiotic crusts; Colorado Plateau; Cryptobiotic soil; Colonization; Nonrandom orientation; Exposure; Collema; Disturbance history; Microhabitat | 2000 |

Adler, Frederick R. | Migration alone can produce persistence of host-parasitoid models | It has long been recognized that the unstable equilibrium of a single-patch predator-prey model cannot be stabilized by diffusive coupling with identical patches, since the coupled system acts exactly like the single-patch system if the patches are synchronized (Maynard Smith 1974; Allen 1975; Reeve... | Heterogeneity; Nicholson-Bailey; migration rates | 1993 |

Capecchi, Mario R. | Modeling alveolar soft part sarcomagenesis in the mouse: a role for lactate in the tumor microenvironment | Alveolar soft part sarcoma (ASPS), a deadly soft tissue malignancy with a predilection for adolescents and young adults, associates consistently with t(X;17) translocations that generate the fusion gene ASPSCR1-TFE3. We proved the oncogenic capacity of this fusion gene by driving sarcomagenesis in m... | 2014-01-01 | |

Seger, Jon | Models of sex ratio evolution | Our understanding of sex ratio evolution depends strongly on models that identify: (1) constraints on the production of male and female offspring, and (2) fitness consequences entailed by the production of different attainable brood sex ratios.

Olivera, Baldomero M. | Modulation of conotoxin structure and function is achieved through a multienzyme complex in the venom glands of cone snails | Background: Conotoxins can be utilized to investigate enzyme-assisted folding of disulfide-rich peptides. Results: Various ER-resident cone snail enzymes act in concert to accelerate the oxidative folding of conotoxins and modulate their conformation by reconfiguring disulfide connectivities. Conclu... | 2012-01-01 | |

Jorgensen, Erik | Molecular basis of synaptic vesicle cargo recognition by the endocytic sorting adaptor stonin 2 | Synaptic transmission depends on clathrin-mediated recycling of synaptic vesicles (SVs). How select SV proteins are targeted for internalization has remained elusive. Stonins are evolutionarily conserved adaptors dedicated to endocytic sorting of the SV protein synaptotagmin. Our data identify the m... | 2007 | |

Blair, David F. | MotA protein of E. coli is a proton-conducting component of the flagellar motor | A number of mutants of motA, a gene necessary for flagellar rotation in E. coli, were isolated and characterized. Many mutations were dominant, owing to competition between functional and nonfunctional MotA for a limited number of sites on the flagellar motor. A new class of mutant was discovered... | MotA protein; MotA gene; Flagellar motor; Proton-conducting | 1990 |

Goller, Franz | Motor control of crystallized song is modified by sensory feedback | Song production requires precisely coordinated activity in the respiratory and syringcal (vocal organ) muscles. Crystallized adult song is characterized by acoustic and motor stereotypy which does not require auditory feedback, suggesting it is represented by fixed central motor programs.
