1. Population analysis of the GLB1 gene in South Brazil
Infantile GM1 gangliosidosis is caused by the absence or reduction of lysosomal beta-galactosidase activity. Studies conducted in Brazil have indicated that it is one of the most frequent lysosomal storage disorders in the southern part of the country. To assess the incidence of this disorder, 390 blood donors were tested for the presence of two common mutat

3. Transient high-level expression of B-galactosidase after transfection of fibroplasts from GM1 gangliosidosis patients with plasmid DNA
GM1 gangliosidosis is an autosomal recessive disorder caused by the deficiency of lysosomal acid hydrolase ß-galactosidase (ß-Gal). It is one of the most frequent lysosomal storage disorders in Brazil, with an estimated frequency of 1:17,000. The enzyme is secreted and can be captured by deficient cells and targeted to the lysosomes. There is no effective

5. Detecção de cinco novas mutações em pacientes brasileiros com gangliosidose GM1
A Gangliosidose GM1 é um Erro Inato do Metabolismo (EIM) causado pela deficiência da enzima B-galactosidase ácida. Essa doença é caracterizada pelo acúmulo de metabólitos não degradados, principalmente gangliosídeo GM1, nos lisossomos de vários tipos celulares. Baseado na idade de início e na atividade residual da enzima, a Gangliosidose GM1 é cl

6. Perfil de expressão genica de leucemias agudas por tecnica de microarranjo (microarrays) / Study of gene expression profile in acute leukemias by microarray assay
The development of gene expression assays, such as cDNA microarrays, has permitted the simultaneous study of several genes; one of this methods is the cDNA microarrays. These investigations contribute to the classification of diseases, comprehension of tumoral biology and, finally, the determination of genetically related prognostic factors. In this present

7. Molecular Basis for Allelic Polymorphism of the Maize Globulin-1 Gene
An abundant protein in maize (Zea mays L.) embryos is a storage globulin encoded by the polymorphic Glb1 gene. Several Glb1 protein size alleles and a null allele have been described. Here we report the isolation and nucleotide sequence analysis of genomic clones corresponding to two Glb1 size alleles (Glb1-L and Glb1-S) and to the Glb1-0 null allele. The Gl

8. Expression of the REB transcriptional activator in rice grains improves the yield of recombinant proteins whose genes are controlled by a Reb-responsive promoter
The gene encoding the rice transcription factor, REB (rice endosperm bZIP) was cloned from a bacterial artificial chromosome library of rice. The cloned 6,227-bp-long Reb gene is composed of six exons and five introns and is flanked by a 1.2-kb 5′ promoter and a 1.2-kb 3′ terminator region. The function of the Reb gene was explored by a transient a

9. Increased level of hemoglobin 1 enhances survival of hypoxic stress and promotes early growth in Arabidopsis thaliana
Overexpression of a class 1 Hb (GLB1) protects Arabidopsis thaliana plants from the effects of severe hypoxia. Overexpression of the bifunctional symbiotic Hb (GLB1S) from Parasponia andersonii in A. thaliana also increases survival after hypoxia. Plants overexpressing the Hb 1 protein, mutated to have a low oxygen affinity, are as susceptible to hypoxia as

10. GlbN (cyanoglobin) is a peripheral membrane protein that is restricted to certain Nostoc spp.
The glbN gene of Nostoc commune UTEX 584 is juxtaposed to nifU and nifH, and it encodes a 12-kDa monomeric hemoglobin that binds oxygen with high affinity. In N. commune UTEX 584, maximum accumulation of GlbN occurred in both the heterocysts and vegetative cells of nitrogen-fixing cultures when the rate of oxygen evolution was repressed to less than 25 micro

11. Genetically Controlled Variation of "Acid" β-Galactosidase Detected in Rattus norvegicus by Isoelectric Focusing
Two genetically variant forms of rat "acid" β-galactosidase were found to differ in isoelectric point and pH dependence, but not in thermostability or sensitivity to inhibition by p-mercuribenzoate (PMB). The results of two backcrosses and an intercross indicated that the isoelectric focusing phenotypes are controlled by two codominant alleles at a single a

12. An active role for endogenous β-1,3-glucanase genes in transgene-mediated co-suppression in tobacco
Post-transcriptional gene silencing (PTGS) is characterized by the accumulation of short interfering RNAs that are proposed to mediate sequence-specific degradation of cognate and secondary target mRNAs. In plants, it is unclear to what extent endogenous genes contribute to this process. Here, we address the role of the endogenous target genes in transgene-m
