Bohs, Lynn A. | Transfer of Cyphomandra (Solanaceae) and its species to Solanum | Data from recent molecular studies demonstrate that the genus Cyphomandra is nested within Solanum. Recognition of Cyphomandra as a separate genus therefore is not tenable unless Solanum is broken up into smaller monophyletic units. All Cyphomandra species are transferred to Solanum, necessitating t... | Cyphomandra; Solanum | 1995 |

Capecchi, Mario R. | Genetic interaction between hoxb-5 and hoxb-6 is revealed by nonallelic noncomplementation. | hoxb-5 and hoxb-6 are adjacent genes in the mouse HoxB locus and are members of the homeotic transcription factor complex that governs establishment of the mammalian body plan. To determine the roles of these genes during development, we generated mice with a targeted disruption in each gene.

Eichwald, Ernst; Capecchi, Mario R.; Thomas, Kirk R. | Mouse model for the delta F508 allele of cystic fibrosis | The most common cause of cystic fibrosis is a mutation that deletes phenylalanine 508 in cystic fibrosis transmembrane conductance regulator (CFTR). The delta F508 protein is misprocessed and degraded rather than traveling to the apical membrane. We used a novel strategy to introduce the delta F508 ... | Digestive System; Disease Models, Animal; Electrolytes; Mice, Inbred C57BL | 1995-10 |

Olivera, Baldomero M.; Gray, William Robert | Contryphan is a D-tryptophan-containing Conus peptide | In this report, we document for the first time the occurrence of D-tryptophan in a normally translated polypeptide, contryphan. The peptide, isolated from the venom of the fish-hunting marine snail Conus radiatus, produces the "stiff-tail" syndrome in mice. | Conotoxins; Contryphan; D-tryptophan; Conus peptides; Conus radiatus; Stiff-tail syndrome | 1996 |

Davidson, Diane W. | Tropical arboreal ants: why so abundant? | ANTS ARE AMONG the most numerous and readily observed arthropods of tropical forests. Indeed, based on their standing biomass and many effects on other species, ants (Formicidae) are arguably the dominant arthropod family in the canopies of lowland rain forest trees (Tobin 1995). Others have tried t... | Arboreal ants; Tropics | 1996 |

Bastiani, Michael | Role of the cell surface in neuronal pathfinding | Perhaps the organ of the human body that evokes the most astonishment, and yet is the least understood, is our brain. From the coordination of simple movements, to consciousness and thought, the function of the nervous system relies on the establishment of trillions of precise connections among the... | Axon; molecular guidance code; growth cone | 1996 |

Olivera, Baldomero M. | Identification and characterization of a Ca2+-sensitive nonspecific cation channel underlying prolonged repetitive firing in Aplysia neurons | The afterdischarge of Aplysia bag cell neurons has served as a model system for the study of phosphorylation-mediated changes in neuronal excitability. The nature of the depolarization generating the afterdischarge, however, has remained unclear. We now have found that venom from Conus textile trig... | Ca21-activated nonspecific cation channel; Slow inward current; Ion channel modulation; Afterdischarge; Bursting; Aplysia bag cell neurons; Conus textile; Neurotoxins | 1996 |

Capecchi, Mario R. | Lessons from angiotensin-converting enzyme-deficient mice | Since the first description of renin by Tigerstedt and Bergman [1] in 1898, many papers have described the biochemistry and physiological roles of the reninangiotensin system [2]. A critical component of this system is angiotensin-converting enzyme (ACE), a peptidase which cleaves the inactive pep... | | 1996 |

Olivera, Baldomero M.; Gray, William Robert; McIntosh, J. Michael | New α-conotoxin which targets α3ß2 nicotinic acetylcholine receptors | We have isolated a 16-amino acid peptide from the venom of the marine snail Conus magus which potently blocks nicotinic acetylcholine receptors (nAChRs) composed of α3ß2 subunits.

Jorgensen, Erik | Genetic screens for synaptic function mutants in the nematode C. elegans | The synapse is the site of a remarkable conversion of electrical signals into chemical signals. This conversion takes place when a depolarizing impulse enters the axon terminal and opens voltage-sensitive calcium channels; calcium then flows into the cell and initiates the fusion of synaptic vesicle... | Vesicle; Neurotransmission; Cell | 1996 |
