Isolation and characterization of Schizosaccharomyces pombe mutants defective in cell wall (1-3)beta-D-glucan

Description: Schizosaccharomyces pombe thermosensitive mutants requiring the presence of an osmotic stabilizer to survive and grow at a nonpermissive temperature were isolated. The mutants were genetically and biochemically characterized. In all of them, the phenotype segregated in Mendelian fashion as a single ...

Launching of the yeast 20 s RNA narnavirus by expressing the genomic or antigenomic viral RNA in vivo

Description: 20 S RNA virus is a persistent positive strand RNA virus found in Saccharomyces cerevisiae. The viral genome encodes only its RNA polymerase, p91, and resides in the cytoplasm in the form of a ribonucleoprotein complex with p91. We succeeded in generating 20 S RNA virus in vivo by expressing, from a...

Transepithelial transport and metabolism of new lipophilic ether derivatives of hydroxytyrosol by enterocyte-like Caco-2/TC7 cells

Description: Intestinal transport and metabolism of a series of ether derivatives of the natural antioxidant hydroxytyrosol with differing alkyl chain lengths (methyl, ethyl, propyl, and butyl) were evaluated at 1, 2, and 4 h using a two-compartment transwell system containing human enterocyte (differentiated Ca...

T Cell activation in vivo targets diacylglycerolk kinase  to the membrane: A novel mechanism for ras attenuation

Description: 7 páginas, 6 figuras -- PAGS nros. 2877-2883 , Diacylglycerol kinase (DGK) phosphorylates diacylglycerol to produce phosphatidic acid, leading to decreased and increased levels, respectively, of these two lipid messengers that play a central role in T cell activation. Nine DGK isoforms, grouped into fi...

Uptake and metabolism of new synthetic lipophilic derivatives, hydroxytyrosyl ethers, by human hepatoma hepg2 cells

Description: As a response to the increasing demand by the food industry for new synthetic lipophilic antioxidants, hydroxytyrosyl methyl, ethyl, propyl and butyl ethers have been synthesized from hydroxytyrosol, with similar or even higher antioxidant activity than free hydroxytyrosol. The uptake and metabolism...

Launching the yeast 23S RNA Narnavirus shows 5′ and 3′ cis-acting signals for replication

Description: Narnavirus 23S RNA is a persistent positive-stranded RNA virus found in yeast Saccharomyces cerevisiae. The viral genome (2.9 kb) only encodes its RNA-dependent RNA polymerase, p104. Here we report the generation of 23S RNA virus, with high frequency, from a vector containing the entire viral cDNA s...

Localisation of the Schizosaccharomyces pombe rho1p GTPase and its involvement in the organisation of the actin cytoskeleton

Description: The Schizosaccharomyces pombe rho1p GTPase directly activates the (1-3) beta-D-glucan synthase and participates in the regulation of cell wall growth and morphogenesis in this fission yeast. Indirect immunofluorescence experiments using rho1p tagged with hemagglutinin have revealed that rho1p was lo...

Isolation of a heat-resistant allegen from the fish parasite Anisakis simplex

Description: 5 páginas, 5 figuras -- PAGS nros. 285-289 , The thermal stability of allergenic peptides from the fish parasite Anisakis simplex has not been fully elucidated. This is of special relevance for physicians who should clearly indicate if sensitized patients should avoid ingestion of raw fish only or whet...
