13. Influence of ovarian hormones deprivation on gene expression in the lower urinary tract of rats
OBJECTIVE: Identify the influence of ovarian hormone deprivation in expression genes on the lower urinary tract of rats. MATERIALS AND METHODS: This study deals with gene screening on lower urinary tract of rats. Fifty isogenic rats divided in two groups of twenty-five animals have their lower urinary tract surgically removed: group I, ovariectomized rats 30

14. Genes determinantes de patogenicidade e virulência e análise parcial do genoma mitocondrial de Colletotrichum lindemuthianum, agente causal da antracnose do feijoeiro comum / Pathogenicity and virulence determinant genes and partial analysis of the mitochondrial genome of Colletotrichum lindemuthianum, causal agent of anthracnose of common bean
Colletotrichum lindemuthianum é um dos principais patógenos do feijoeiro comum (Phaseolus vulgaris) em regiões tropicais. Nesse trabalho são descritos três mutantes de C. lindemuthianum obtidos por mutagênese insercional usando a técnica REMI (Integração Mediada por Enzima de Restrição), com a capacidade alterada de infectar o hospedeiro, e a cara

15. Potential effect of the antineoplasic Paclitaxel (Taxol) in the experimental inflammatory hyperalgisia induced by zymosan. / Efeito potencializador do antineoplásico paclitaxel (taxol) na hiperalgesia inflamatória experimental induzida por zymosan.
Paclitaxel (Taxol) was the first effective antineoplastic in the management of refractory neoplasias to the conventional chemotherapy. It induces clinically to myelosuppression and sensory peripheral neuropathy boundary and cumulative dose, well documented at literature already. Less often the patients exhibited myalgias and arthralgias. As to concern to the

16. Estudo da função de tiorredoxina peroxidase citoplasmatica I em Saccharomyces cerevisiae
Cytosolic thioredoxin peroxidase I (cTPxI) is a Saccharomyces cerevisiae antioxidant enzyme that belongs to peroxiredoxins family, conserved from bacteria to humans, able to reduce hydroperoxides in the presence of a thiol substrate. Our study concerning its role in yeast cells demonstrated that CTPXI is highly expressed in cells exposed to different H2O2 co

17. Insertion/deletion polymorphism of the angiotensin I-converting enzyme gene in patients with heart failure / Polimorfismo de inserção/deleção do gene da enzima de conversão da angiotensina I em portadores de insuficiência cardíaca
Insertion/deletion (I/D) polymorphism of the angiotensin I- converting enzyme gene was studied in a cohort of survivors of 333 patients with heart failure of different etiologies and in a control group of 807 volunteer blood donors. The age of the patients ranged from 13 to 68 (43,3 ± 10,5) years, 262 (78.7%) were men and 71 (21.3%) women. The age of the co

18. Disruption of the yeast nuclear PET54 gene blocks excision of mitochondrial intron aI5 beta from pre-mRNA for cytochrome c oxidase subunit I.
The nuclear PET54 gene of Saccharomyces cerevisiae was cloned and a pet54::LEU2 gene disruption strain was constructed. Analysis of the phenotype of this strain revealed a defect in expression of two mitochondrial genes: COX1, which encodes cytochrome c oxidase subunit I, and COX3, which encodes cytochrome c oxidase subunit III. The defect in COX1 gene expre

19. The cytochrome oxidase subunit I and subunit III genes in Oenothera mitochondria are transcribed from identical promoter sequences
Two loci encoding subunit III of the cytochrome oxidase (COX) in Oenothera mitochondria have been identified from a cDNA library of mitochondrial transcripts. A 657-bp sequence block upstream from the open reading frame is also present in the two copies of the COX subunit I gene and is presumably involved in homologous sequence rearrangement. The proximal po

20. Interleukin-4 inhibits prostaglandin E2 production by freshly prepared adherent rheumatoid synovial cells via inhibition of biosynthesis and gene expression of cyclo-oxygenase II but not of cyclo-oxygenase I.
OBJECTIVE: To characterise the effect of interleukin-4 (IL-4) on the biosynthesis of cyclo-oxygenases I (COX I) and II (COX II), the rate limiting enzymes of the synthesis of prostaglandin E2 (PGE2), in freshly prepared rheumatoid synovial cells. METHODS: Adherent synovial cells were obtained from rheumatoid synovium by collagenase digestion. The concentrati

21. Differential effectiveness of yeast cytochrome c oxidase subunit genes results from differences in expression not function.
In Saccharomyces cerevisiae, COX5a and COX5b encode two distinct forms of cytochrome c oxidase subunit V, Va and Vb, respectively. To determine the relative contribution of COX5a and COX5b to cytochrome c oxidase function, we have disrupted each gene. Cytochrome c oxidase activity levels and respiration rates of strains carrying null alleles of COX5a or COX5

22. Cytochrome c oxidase III as a mechanism for apoptosis in heart failure following myocardial infarction
Cytochrome c oxidase (COX) is composed of 13 subunits, of which COX I, II, and III are encoded by a mitochondrial gene. COX I and II function as the main catalytic components, but the function of COX III is unclear. Because myocardial ischemia affects mitochondrial oxidative metabolism, we hypothesized that COX activity and expression would be affected durin

23. Genetic evidence that different functional domains of the PET54 gene product facilitate expression of the mitochondrial genes COX1 and COX3 in Saccharomyces cerevisiae.
Expression of the yeast mitochondrial genes COX1 and COX3, which encode subunits I and III of cytochrome oxidase, respectively, is controlled by a common nuclear-encoded trans-acting factor. This protein, encoded by the PET54 gene, controls expression of COX1 at the level of RNA splicing and COX3 at the level of mRNA translation. While the steps of COX1 and
