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 |

Capecchi, Mario R. | Fundamental cellular processes do not require vertebrate-specific sequences within the TATA-binding protein. | The 180-amino acid core of the TATA-binding protein (TBPcore) is conserved from Archae bacteria to man. Vertebrate TBPs contain, in addition, a large and highly conserved N-terminal region that is not found in other phyla. We have generated a line of mice in which the tbp allele is replaced with a v... | Mice, Knockout; Cells, Cultured; Fibroblasts; Embryo | 2003-02-21 |

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. | Hoxb13 mutations cause overgrowth of caudal spinal cord and tail vertebrae | To address the expression and function of Hoxb13, the 5' most Hox gene in the HoxB cluster, we have generated mice with loss-of-function and beta-galactosidase reporter insertion alleles of this gene. Mice homozygous for Hoxb13 loss-of-function mutations show overgrowth in all major structures deriv... | Animals; Axons; Ganglia, Spinal; Mice; Spinal Cord | 2003-04-15 |

Capecchi, Mario R. | Xanthine oxidoreductase is central to the evolution and function of the innate immune system. | The housekeeping enzyme xanthine oxidoreductase (XOR) has been studied intensively over the past 100 years, yet the complexity of its in vivo function is still poorly understood. A large body of literature focuses on the different catalyltic forms of XOR and their importance in the synthesis of reac... | Animals; Gene Expression Regulation, Enzymologic; Humans; Immune System; Models, Biological | 2003-09-01 |
