Mathematical Modeling of Polyamine Metabolism in Mammals.
(Elsevier, 2006)Polyamines are considered as essential compounds in living cells, since they are involved in cell proliferation, transcription, and translation processes. Furthermore, polyamine homeostasis is necessary to cell survival, ... -
Causes of B chromosome variant substitution in the grasshopper Eyprepocnemis plorans
(Springer, 2006)We have analysed B chromosome frequency for three consecutive years, B transmission rate at population and individual levels, clutch size, egg fertility and embryoYadult viability in a natural population of the ... -
Detection of B chromosomes in interphase hemolymph nuclei from living specimens of the grasshopper Eyprepocnemis plorans
(Karger, 2006)The two most important evolutionary properties of B chromosomes are their transmission rate (which suggests their selfishness when significantly higher than 0.5) and their net effects on carrier fitness (usually negative ... -
Isolation, characterization, and localization of AgaSGNH cDNA: a new SGNH-motif plant hydrolase specific to Agave americana L. leaf epidermis.
(Oxford University Press, 2007-07-03)GDSL and SGNH hydrolases are lipases involved in a wide range of functions, behaving in many cases as bifunctional enzymes. In this work, the isolation and characterization of AgaSGNH, a cDNA encoding a member of the ... -
Effect of salt on ROS homeostasis, lipid peroxidation and antioxidant mechanisms in Pinus pinaster suspension cells.
(INRA EDP Sciences, 2009-01)In the Pinus genus, information on the effectiveness of oxidative defence mechanisms during exposure to salt is lacking. The effect of salt stress imposition on ROS homeostasis was investigated using maritime pine (Pinus ... -
Modification of plant hormone levels and signaling as a tool in plant biotechnology.
(Wiley, 2009-09-23)Plant hormones are signal molecules, present in trace quantities, that act as major regulators of plant growth and development. They are involved in a wide range of processes such as elongation, flowering, root formation ... -
When metabolism meets topology: Reconciling metabolite and reaction networks.
(Wiley, 2010)The search for a systems-level picture of metabolism as a web of molecular interactions provides a paradigmatic example of how the methods used to characterize a system can bias the interpretation of its functional meaning. ... -
Effects of B Chromosomes on Egg Fertility and Clutch Size in the Grasshopper Eyprepocnemis plorans
(Pensoft, 2010)We analyse here three components of reproductive success (egg fertility, egg clutch size and embryo clutch size) in several temporal samples from different Spanish and Moroccan populations of the grasshopper Eyprepocnemis ... -
Generation and analysis of ESTs from strawberry (Fragaria xananassa) fruits and evaluation of their utility in genetic and molecular studies
(BMC, 2010-09-17)Cultivated strawberry is a octoploid species whose fruit is highly appreciated due to its organoleptic properties and health benefits. However, information about the role played by different hormones on these processes ... -
Transient protein-protein interactions: structural, functional, and network properties
(Elsevier, 2010-10-13)Transient interactions, which involve protein interactions that are formed and broken easily, are important in many aspects of cellular function. Here we describe structural and functional properties of transient interactions ... -
CXCL5 mediates UVB irradiation-induced pain.
(AAAS, 2011-07-06)Many persistent pain states (pain lasting for hours, days, or longer) are poorly treated because of the limitations of existing therapies. Analgesics such as nonsteroidal anti-inflammatory drugs and opioids often provide ... -
Cocaine modulates both glutaminase gene expression and glutaminase activity in the brain of cocaine-sensitized mice
(Springer, 2012)Glutaminase is considered the main Glutamate (Glu) producing enzyme. Two isoforms, liver (LGA) and kidney (KGA) type glutaminases have been identified in neurons. The role of both enzymes in psychopharmacological responses ... -
Attenuation of cocaine-induced conditioned locomotion is associated with altered expression of hippocampal glutamate receptors in mice lacking LPA1 receptors.
(Springer, 2012)Lysophosphatidic acid is a phospholipid mediator that modulates neurodevelopment and neurogenesis in the hippocampus through its actions on LPA1 receptors. Emerging evidences support LPA1 as a mediator of learning and ... -
Nucleolus size varies with sex, ploidy and gene dosage in insects
(Wiley, 2012)The nucleolus constitutes a cytologically visible phenotype for ribosomal DNA (rDNA). Nucleolar size, as determined by silver staining, is a good indicator of cell proliferation rate and biosynthetic activity. Nevertheless, ... -
Gene3D: a domain-based resource for comparative genomics, functional annotation and protein network analysis
(Oxford University Press, 2012-01)Gene3D http://gene3d.biochem.ucl.ac.uk is a comprehensive database of protein domain assignments for sequences from the major sequence databases. Domains are directly mapped from structures in the CATH database or predicted ... -
Genetic and genome-wide transcriptomic analyses identify co- regulation of oxidative response and hormone transcript abundance with vitamin C content in tomato fruit.
(BioMed Central, 2012-05-14)L-ascorbic acid (AsA; vitamin C) is essential for all living plants where it functions as the main hydrosoluble antioxidant. It has diverse roles in the regulation of plant cell growth and expansion, photosynthesis, and ... -
Mammalian Glutaminase Gls2 Gene Encodes Two Functional Alternative Transcripts by a Surrogate Promoter Usage Mechanism.
(PLOS, 2012-06-05)Glutaminase is expressed in most mammalian tissues and cancer cells, but the regulation of its expression is poorly understood. An essential step to accomplish this goal is the characterization of its species- and cell-specific ... -
ReadqPCR and NormqPCR: R packages for the reading, quality checking and normalisation of RT-qPCR quantification cycle (Cq) data
(BMC, 2012-07)Background: Measuring gene transcription using real-time reverse transcription polymerase chain reaction (RT-qPCR) technology is a mainstay of molecular biology. Technologies now exist to measure the abundance of many ... -
Alteration of the Interconversion of Pyruvate and Malate in the Plastid or Cytosol of Ripening Tomato Fruit Invokes Diverse Consequences on Sugar But Similar Effects on Cellular Organic Acid, Metabolism, and Transitory Starch Accumulation.
(Oxford Academic, 2012-12-18)The aim of this work was to investigate the effect of decreased cytosolic phosphoenolpyruvate carboxykinase (PEPCK) and plastidic NADP-dependent malic enzyme (NADP-ME) on tomato (Solanum lycopersicum) ripening. Transgenic ... -
