51 Capecchi, Mario R.Hoxc13 mutant mice lack external hairHox genes are usually expressed temporally and spatially in a colinear manner with respect to their positions in the Hox complex. Consistent with the expected pattern for a paralogous group 13 member, early embryonic Hoxc13 expression is found in the nails and tail. Hoxc13 is also expressed in vibri...Filiform papillae; Homozygotes; Paralogous1998-01-01
52 Coffin, Cheryl M.; Capecchi, Mario R.Alveolar rhabdomyosarcomas in conditional Pax3:Fkhr mice: cooperativity of Ink4a/ARF and Trp53 loss of function.Alveolar rhabdomyosarcoma is an aggressive childhood muscle cancer for which outcomes are poor when the disease is advanced. Although well-developed mouse models exist for embryonal and pleomorphic rhabdomyosarcomas, neither a spontaneous nor a transgenic mouse model of alveolar rhabdomyosarcoma has...Cell Differentiation; Forkhead Transcription Factors; Myogenic Regulatory Factors2004-11-01

55 Digre, Kathleen B.; Gouw, Launce G.; Harris, Catherine P.; Haines, John H.; Ptacek, L.J.Autosomal dominant cerebellar ataxia with retinal degeneration: clinical, neuropathologic, and genetic analysis of a large kindred.The autosomal dominant cerebellar ataxias (ADCA) comprise a heterogeneous group of neurologic disorders characterized by degeneration of the cerebellum, spinal cord, and brainstem. Genetic analysis has revealed two loci, SCA1 on chromosome 6p, and SCA2 on chromosome 12q, responsible for some ADCA. W...Retinal Degeneration; Cerebellar Ataxia; Genetic Analysis1994-08
56 Gesteland, Raymond F.; Atkins, John F.; Felden, Brice; McCutcheon, John P.Probing the structure of the Escherichia coli 10Sa RNA (tmRNA)The conformation of the Escherichia coli 10Sa RNA (tmRNA) in solution was investigated using chemical and enzymatic probes. Single- and double-stranded domains were identified by hydrolysis of tmRNA in imidazole buffer and by lead(II)-induced cleavages.

57 Kerber, Richard A.Mitochondrial genomic analysis of late onset alzheimers disease reveals protective haplogroups H6A1A/H6A1B: the Cache County study on memory in agingBackground: Alzheimer's disease (AD) is the most common cause of dementia and AD risk clusters within families. Part of the familial aggregation of AD is accounted for by excess maternal vs. paternal inheritance, a pattern consistent with mitochondrial inheritance. The role of specific mitochondrial...2012-01-01
58 Thomas, Kirk R.; Capecchi, Mario R.Efficient correction of mismatched bases in plasmid heteroduplexes injected into cultured mammalian cell nuclei.Heteroduplexes were prepared from two plasmids, pRH4-14/TK and pRH5-8/TK, containing different amber mutations in the neomycin resistance gene (Neor).

A functional Neor gene conferred kanamycin resistance to bacteria...Cell Nucleus; Cells, Cultured; Microinjections1985-01
59 Capecchi, Mario R.; Tvrdik, PetrHoxb1 functions in both motoneurons and in tissues of the periphery to establish and maintain the proper neuronal circuitry.Formation of neuronal circuits in the head requires the coordinated development of neurons within the central nervous system (CNS) and neural crest-derived peripheral target tissues. Hoxb1, which is expressed throughout rhombomere 4 (r4), has been shown to be required for the specification of facial...Rhombomere 4; Branchiomotor; Cranial Nerve2004-07-04

METHODS: 7G6 immunocytochemistry was performed on sections of human, primate, and bovine retina. The antigen was immunoprecipitated from human retinal lysates and purified with protein ...Cones (Retina); Molecular Sequence Data; Phototransduction2003
62 Light, Alan R.Activation of Src family kinases in spinal microglia contributes to formalin-induced persistent pain state through p38 pathwayProtein tyrosine phosphorylation has been implicated in normal and pathological functions, such as cell proliferation, migration and differentiation. Recently, some studies have shown that Src family kinases (SFKs) were involved in neurological disorders and neuropathic pain states in which microgli...2012-01-01
63 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; Hindlimb2003-07-18

66 Couldwell, William T.; Gillespie, David L.; Jensen, Randy L.Comparison of the cell lines used in meningoma researchBackground: Immortal cell lines and cell lines derived from operative specimens transplanted into animal models are used in meningioma research.

67 Capecchi, Mario R.Removing the vertebrate-specific TBP N terminus disrupts placental beta2m-dependent interactions with the maternal immune systemMammalian 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 Protein2002-07-12

69 Couldwell, William T.; Jensen, Randy L.; Gillespie, David L.Celecoxib inhibits meningioma tumor growth in a mouse xenograft modelBackground: Treatments for recurrent meningiomas are limited. We previously demonstrated universal expression of COX-2 in meningiomas and dose-dependent growth inhibition in vitro with celecoxib, a COX-2 inhibitor. We therefore tested the effects of celecoxib on meningioma growth in a mouse xenograf...Meningioma; Cyclooxygenase-2; COX-2; Celecoxib2007
70 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; Plasmids1986-11-06
71 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; Mice2000-02-10
