Plant-antivenom: Database of anti-venom medicinal plants
(UNIV CATOLICA DE VALPARAISO, 2011)
Plant-antivenom is a computational Websystem about medicinal plants with anti-venom properties. The system consists of a database of these plants, including scientific publications on this subject and amino acid sequences ...
Claudin expression is dysregulated in prostate adenocarcinomas but does not correlate with main clinicopathological parameters
(LIPPINCOTT WILLIAMS & WILKINS, 2011)
Aims: Claudins, a large family of essential tight junction (TJ) proteins, are abnormally regulated in human carcinomas. The aim of this study was to determine the expression of claudins 1, 2, 3, 4, 5, 7, and 11 in prostate ...
CztR, a LysR-Type Transcriptional Regulator Involved in Zinc Homeostasis and Oxidative Stress Defense in Caulobacter crescentus
(AMER SOC MICROBIOLOGY, 2010)
Caulobacter crescentus is a free-living alphaproteobacterium that has 11 predicted LysR-type transcriptional regulators (LTTRs). Previously, a C. crescentus mutant strain with a mini-Tn5lacZ transposon inserted into a gene ...
Oxidative stress protection of Trypanosomes requires selenophosphate synthase
(ELSEVIER SCIENCE BV, 2011)
Selenoproteins are characterized by the incorporation of at least one amino acid selenocysteine (Sec-U) encoded by in-frame UGA stop codons. These proteins, as well as the components of the Sec synthesis pathway, are present ...
The role of mitochondrial DNA damage in the citotoxicity of reactive oxygen species
(SPRINGER/PLENUM PUBLISHERS, 2011)
Mitochondria contain their own genome, a small circular molecule of around 16.5 kbases. The mitochondrial DNA (mtDNA) encodes for only 13 polypeptides, but its integrity is essential for mitochondrial function, as all 13 ...
A two-component system, an anti-sigma factor and two paralogous ECF sigma factors are involved in the control of general stress response in Caulobacter crescentus
(WILEY-BLACKWELL, 2011)
The extracytoplasmic function sigma factor sigma(T) is the master regulator of general stress response in Caulobacter crescentus and controls the expression of its paralogue sigma(U). In this work we showed that PhyR and ...
Aspergillus fumigatus calcineurin interacts with a nucleoside diphosphate kinase
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
The Ca2+-calcineurin pathway affects virulence and morphogenesis in filamentous fungi. Here, we identified 37 CalA-interacting proteins that interact with the catalytic subunit of calcineurin (CalA) in Aspergillus fumigatus, ...
The role of cytoskeleton, components of inositol phospholipid signaling pathway and iron in Ehrlichia canis in vitro proliferation
(SPRINGERDORDRECHT, 2012)
Ehrlichia canis, etiologic agent of Canine Monocytic Ehrlichiosis, is an obligatory intracellular bacterium that parasitizes monocytes and macrophages. In this study we analyzed the role of the cytoskeleton specifically ...
Exogenous Cx43 expression decrease cell proliferation rate in rat hepatocarcinoma cells independently of functional gap junction
(BMC, 2009-08-13)
Abstract
Background
Gap junction intercellular communication (GJIC) is considered to play a role in the regulation of homeostasis because it regulates important processes, ...
Estimating Amino Acid Requirement of Brazilian Freshwater Fish from Muscle Amino Acid Profile
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Information on nutritional requirement of some Brazilian farmed fish species, especially essential amino acids (EAA) requirements, is scarce. The estimation of amino acids requirements based on amino acid composition of ...
