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 |

Levy, James A. | Context-specific memory and apolipoprotein E (ApoE) epsilon 4: cognitive evidence from the NIMH prospective study of risk for Alzheimer's disease. | The aim of the study was to determine whether the epsilon 4 allele of the apolipoprotein E (ApoE) gene was associated primarily with context-specific memory among individuals at genetic risk for developing Alzheimer's disease. The effect of ApoE status on comprehensive neuropsychological results was... | Alleles; Apolipoprotein E4; Mental Status Schedule | 2004-05-10 |

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.

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 |

Capecchi, Mario R. | Hoxb8 is required for normal grooming behavior in mice. | Repertoires of grooming behaviors critical to survival are exhibited by most animal species, including humans. Genes that influence this complex behavior are unknown. We report that mice with disruptions of Hoxb8 show, with 100% penetrance, excessive grooming leading to hair removal and lesions.

Thomas, Kirk R.; Capecchi, Mario R. | Maintenance of functional equivalence during paralogous Hox gene evolution. | Biological diversity is driven mainly by gene duplication followed by mutation and selection. This divergence in either regulatory or protein-coding sequences can result in quite different biological functions for even closely related genes. This concept is exemplified by the mammalian Hox gene comp... | Alleles; Animals; Cervical Vertebrae; Embryo; Genetic Complementation Test; Homeodomain Proteins; Homozygote; Mice | 2000-02-10 |

Capecchi, Mario R. | Removing the vertebrate-specific TBP N terminus disrupts placental beta2m-dependent interactions with the maternal immune system | Mammalian TBP consists of a 180 amino acid core that is common to all eukaryotes, fused to a vertebrate-specific N-terminal domain. We generated mice having a modified tbp allele, tbp(DeltaN), that produces a version of TBP lacking 111 of the 135 vertebrate-specific amino acids. Most tbp(DeltaN/Delt... | Alleles; Animals, Genetically Modified; Binding Sites; Embryonic and Fetal Development; Evolution, Molecular; Female; Fetus; Immune Tolerance; Male; Mice; Mutation; ATA-Box Binding Protein | 2002-07-12 |
