| 1 |  | Capecchi, Mario R. | Choose your target. | The technology of modifying endogenous genes has recently been extended from mice to Drosophila and sheep. Concurrently, genomic sequencing is uncovering thousands of previously uncharacterized genes. Armed with today's technologies, what are our best options for delineating the functions of these n... | Animals; Mice; Sheep | 2000-09-13 |
| 2 |  | Moon, Ann M.; Capecchi, Mario R. | Fgf8 is required for outgrowth and patterning of the limbs. | The expression pattern and activity of fibroblast growth factor-8 (FGF8) in experimental assays indicate that it has important roles in limb development, but early embryonic lethality resulting from mutation of Fgf8 in the germ line of mice has prevented direct assessment of these roles. Here we rep... | Animals; Body Patterning; Bone Morphogenetic Proteins; Ectoderm | 2000-12-26 |
| 3 |  | Capecchi, Mario R. | How close are we to implementing gene targeting in animals other than the mouse? | Describes several significant contributions that bring us much closer to extending ‘‘gene targeting'' to mammalian species other than the mouse. Gene targeting now provides the means for creating new strains of mice with mutations in virtually any gene. First, the desired mutation is introduced ... | Cattle; Mutagenesis; Mice; Humans; Ethics, Medical | 2000-02-01 |
| 4 |  | Capecchi, Mario R. | Illegitimate cre-dependent chromosome rearrangements in transgenic mouse spermatids. | The bacteriophage P1 Cre/loxP system has become a powerful tool for in vivo manipulation of the genomes of transgenic mice. Although in vitro studies have shown that Cre can catalyze recombination between cryptic "pseudo-loxP" sites in mammalian genomes, to date there have been no reports of loxP-si... | Chromatin; Female; Mice, Inbred C57BL; Phenotype | 2000-12-05 |
| 5 |  | Capecchi, Mario R. | Lack of angiotensin II-facilitated erythropoiesis causes anemia in angiotensin-converting enzyme-deficient mice | While nephrologists often observe reduced hematocrit associated with inhibitors of angiotensin-converting enzyme (ACE), the basis for this effect is not well understood. We now report that two strains of ACE knockout mice have a normocytic anemia associated with elevated plasma erythropoietin levels... | ACE | 2000-10-31 |
| 6 |  | 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 |
