1. Genomic analysis of Brazilian patients with Fabry disease
Fabry disease is an X-linked lysosomal disorder due to a-galactosidase A deficiency that causes storage of globotriaosylceramide. The gene coding for this lysosomal enzyme is located on the long arm of the X chromosome, in region Xq21.33-Xq22. Disease progression leads to vascular disease secondary to involvement of kidney, heart and the central nervous syst

2. A case of heterozygous Fabry's disease with a short PR interval and giant negative T waves.
A 55 year old woman with heterozygous Fabry's disease presented with cardiac symptoms. The electrocardiogram showed a PR interval of 0.12 s and giant negative T waves, suggesting apical hypertrophic cardiomyopathy. Endomyocardial biopsy, however, revealed myelin like substances characteristic of Fabry's disease. Increasing thickness of the left ventricular w

3. Analysis of Catabolite Control Protein A-Dependent Repression in Staphylococcus xylosus by a Genomic Reporter Gene System
A single-copy reporter system for Staphylococcus xylosus has been developed, that uses a promoterless version of the endogenous β-galactosidase gene lacH as a reporter gene and that allows integration of promoters cloned in front of lacH into the lactose utilization gene cluster by homologous recombination. The system was applied to analyze carbon catabolit

4. Isolation and characterization of a recombinant lambda gt11 bacteriophage which expresses an immunoreactive Mycobacterium intracellulare protein in Escherichia coli.
Disseminated Mycobacterium avium-Mycobacterium intracellulare (M. avium complex) disease is a prevalent opportunistic infection in patients with acquired immune deficiency syndrome. Because of the increasing importance of this disease, an M. avium complex lambda gt11 expression library was prepared. We screened the library with an absorbed anti-M. intracellu

5. Anaerobiosis induces expression of ant, a new Escherichia coli locus with a role in anaerobic electron transport.
Escherichia coli has a formate hydrogenlyase system which allows it to maintain an electron balance during anaerobic growth by passing electrons from formate to H+ ions, thus generating H2. The Mu d1(Ap lac) bacteriophage was used to generate mutants that were defective in passing electrons from formate to benzyl viologen, an artificial electron acceptor. A

6. Structure and regulation of KGD1, the structural gene for yeast alpha-ketoglutarate dehydrogenase.
Nuclear respiratory-defective mutants of Saccharomyces cerevisiae have been screened for lesions in the mitochondrial alpha-ketoglutarate dehydrogenase complex. Strains assigned to complementation group G70 were ascertained to be deficient in enzyme activity due to mutations in the KGD1 gene coding for the alpha-ketoglutarate dehydrogenase component of the c

7. Transcription and translation in a pleiotropic streptomycin-resistant mutant of Escherichia coli.
The role of the ribosomal protein S12 (streptomycin protein) in ribosome function and in other metabolic processes in the cell has been investigated. A spontaneous streptomycin-resistant strain of Escherichia coli (SM3) carrying a mutation in the rpsL gene is deficient in its ability to induce the synthesis of the enzyme bets-galactosidase. It was demonstrat

8. The map of chromosome 20.
The number of gene assignments to human chromosome 20 has increased slowly until recently. Only seven genes and one fragile site were confirmed assignments to chromosome 20 at the Ninth Human Gene Mapping Workshop in September 1987 (HGM9). One fragile site, 13 additional genes, and 10 DNA sequences that identify restriction fragment length polymorphisms (RFL

9. Fusogenic mechanisms of enveloped-virus glycoproteins analyzed by a novel recombinant vaccinia virus-based assay quantitating cell fusion-dependent reporter gene activation.
The fusogenic activities of enveloped-virus glycoproteins were analyzed by using a quantitative, sensitive, rapid, and highly versatile recombinant vaccinia virus-based assay measuring activation of a reporter gene upon fusion of two distinct cell populations. One population uniformly expressed vaccinia virus-encoded viral glycoproteins mediating specific bi

10. Short-term correction of factor VIII deficiency in a murine model of hemophilia A after delivery of adenovirus murine factor VIII in utero
Development of in utero gene transfer approaches may provide therapies for genetic disorders with perinatal morbidity. In hemophilia A, prenatal and postnatal bleeding may be catastrophic, and modest increments in factor VIII (FVIII) activity are therapeutic. We performed transuterine i.p. gene transfer at day 15 of gestation in a murine model of hemophilia

11. Consequences of DNA-Dependent Protein Kinase Catalytic Subunit Deficiency on Recombinant Adeno-Associated Virus Genome Circularization and Heterodimerization in Muscle Tissue
Circular concatemerization of the recombinant adeno-associated virus (rAAV) genome has been suggested as the predominant process facilitating long-term rAAV transduction in muscle. A recent study (S. Song, P. J. Laipis, K. I. Berns, and T. R. Flotte, Proc. Natl. Acad. Sci. USA 98:4084-4088, 2001) with SCID mice, which are defective in the DNA-dependent prote
