Nucleotide levels

WhenSaccharomyces cerevisiaecells, grown in galactose, glucose or mannose, were treated with 1.5 mMhydrogen peroxide (H2O2) for 30 min, an important decrease in the ATP, and a less extensive decrease in the GTP, CTP, UTP and ADP-ribose levels was estimated. Concomitantly a net increase in the inosine levels was observed. Treatment with 83mMmenadionepromoted theappearanceof acompound similar to adenosine but no appreciable changes in the nucleotide content of yeast cells, grown either in glucose or galactose....

Volkensin, a type 2 ribosome-inactivating protein from the roots of Adenia volkensiiHarms (kilyambiti plant) was characterized both at the protein and nucleotide level by direct amino acid sequencing and cloning of the gene enco-ding the protein. Gene sequence analysis revealed that vol-kensin is encoded by a 1569-bp ORF (523 amino acid residues) without introns, withan internal linker sequence of 45 bp.

The activity of NTPDase (EC 3.6.1.5, apyrase, CD39) was verified in plate-lets from patients with increasing cholesterol levels. A possible association between cholesterol levels and inflammatory markers, such as oxidized low-density lipoprotein, highly sensitive C-reactive protein and oxidized low-density lipoprotein autoantibodies, was also investigated.

This study characterized the human apolipoprotein H [APOH; b2-glycopro-tein I (b2GPI)] promoter and its variants byin vitro functional experiments and investigated their relationship with human plasmab2GPI levels. We examined the individual effects of 12 APOHpromoter single nucleotide polymorphisms in the 5¢ flanking region ofAPOH(1.4 kb) on luciferase activity in COS-1 cells and HepG2 cells and their impact on plasma...

Cyclophilin D was recently shown to bind to and decrease the activity of F0F1 -ATP synthase in submitochondrial particles and permeabilized mito-chondria [Giorgio Vet al. (2009) J Biol Chem, 284, 33982–33988]. Cyclo-philin D binding decreased both ATP synthesis and hydrolysis rates.
