Changes in free polyamine levels, expression of polyamine biosynthesis genes, and performance of rice cultivars under salt stress: a comparison with responses to drought.
Potsdam, Germany. In Front Plant Sci, 2013
Based on expression profiles, investigated genes were divided into generally stress-induced genes (ADC2, SPD/SPM2, SPD/SPM3), one generally stress-repressed gene (ADC1), constitutively expressed genes (CPA1, CPA2, CPA4, SAMDC1, SPD/SPM1), specifically drought-induced genes (SAMDC2, AIH), one specifically drought-repressed gene (CPA3) and one specifically salt-stress repressed gene (SAMDC4), revealing both overlapping and specific stress responses under these conditions.
Transgene induced co-suppression during vegetative growth in Cryptococcus neoformans.
Durham, United States. In Plos Genet, 2011
Multiple copies of the cpa1::ADE2 transgene were ectopically integrated into the genome, leading to silencing of the endogenous CPA1 and CPA2 genes encoding the cyclosporine A target protein cyclophilin A. Given that CPA1-derived antisense siRNAs were detected in the silenced isolates, and that RNAi components (Rdp1, Ago1, and Dcr2) are required for silencing, we hypothesize that an RNAi pathway is involved, in which siRNAs function as trans factors to silence both the CPA1 and the CPA2 genes.
Reverse transcription polymerase chain reaction (RT-PCR) analysis of proteolytic enzymes in cultures of human respiratory epithelial cells.
Dublin, Ireland. In J Aerosol Med Pulm Drug Deliv, 2011
METHODS: The mRNA expression of proteolytic enzymes (i.e., carboxypeptidases: CPA1, CPA2, CPB, CPM; gamma-glutamyltransferases: GGT1, GGT2; angiotensin-converting enzymes: ACE, ACE2; aminopeptidases: APA, APB, APN, APP1, APP2, APP3; endopeptidases: 24.11 (neprilysin), 24.15 (thimet oligopeptidase), 24.18 (meprin A); enteropeptidase; trypsin 1, trypsin 2; neutrophilic elastase; dipeptidyl peptidase 4; gamma-glutamylhydrolase) was investigated by semiquantitative RT-PCR in human bronchial (hBEpC, Calu-3, 16HBE14o-) and alveolar (A549) epithelial cells, respectively.
Detection of differential proteomes associated with the development of type 2 diabetes in the Zucker rat model using the iTRAQ technique.
Seoul, South Korea. In J Proteome Res, 2011
Notably, the novel proteins involved in impaired insulin secretion (Scg2, Anxa2, and Rab10), mitochondrial dysfunction (Atp5b and Atp5l), extracellular matrix proteins (Lgal-1, Vim, and Fbn1), and microvascular ischemia (CPA1, CPA2, CPB, Cela2a, and Cela3b) were observed for the first time.
Evolutionary origins of eukaryotic sodium/proton exchangers.
Baltimore, United States. In Am J Physiol Cell Physiol, 2005
This analysis initially required examining the entire monovalent cation proton antiporter (CPA) superfamily that includes the CPA1, CPA2, and NaT-DC families of transporters, each of which has a unique set of bacterial ancestors.
Genetic mapping of arg, cpa, car and tsm genes in Saccharomyces cerevisiae by trisomic analysis.
Gembloux, Belgium. In Curr Genet, 1982
By use of a set of 8 aneuploid strains of the yeast Saccharomyces cerevisiae, carrying from 1 to 5 identified disomic chromosomes, in crosses to a set of haploid strains collectively bearing 11 unmapped genes, the following chromosome assignments were obtained for these unmapped genes: arg80 on XIII;arg3 on X;car2 on XII; cpa1 and tsm8740 on XV; tsm7269 (=rna6) on II; cpa2 on X or XV; arg82 and tsm4572 on III, IV or XVI; car1 and arg81 on II, IV, VI, VII or XVI.
