Thomas, Kirk R.; Capecchi, Mario R. | Introduction of homologous DNA sequences into mammalian cells induces mutations in the cognate gene. | Injection of homologous DNA sequences into nuclei of cultured mammalian cells induces mutations in the cognate chromosomal gene. It appears that these mutations result from incorrect repair of a heteroduplex formed between the introduced and the chromosomal sequence. This phenomenon is termed 'heter... | Animals; Cell Line; Drug Resistance, Microbial; Fibroblasts; Mice; Models, Genetic; Neomycin; Plasmids | 1986-11-06 |

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. | Purification and characterization of mouse hypoxanthine-guanine phosphoribosyltransferase. | Hypoxanthine-guanine phosphoribosyltransferase (HGPR transferase) (EC 2.4.2.8) has been purified approximately 4500-fold to apparent homogeneity from mouse liver. The procedure involves the use of affinity chromatography and was designed to be readily adaptable to small scale isolations. The enzyme ... | Buffers; Centrifugation, Density Gradient; Chromatography, Affinity; Chromatography, Gel; Chromatography, Ion Exchange; Electrophoresis, Polyacrylamide Gel | 1975-01-31 |

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.

Capecchi, Mario R. | Patterns of integration of DNA microinjected into cultured mammalian cells: evidence for homologous recombination between injected plasmid DNA molecules. | We examined the fate of DNA microinjected into nuclei of cultured mammalian cells. The sequence composition and the physical form of the vector carrying the selectable gene affected the efficiency of DNA-mediated transformation. Introduction of sequences near the simian virus 40 origin of DNA replic... | Base Sequence; Cell Line; Genes, Viral; Genetic Vectors; Mice; Microinjections | 1982-11 |
