Intron-mediated enhancement of gene expression independent of unique intron sequences and splicing.
Either of the first two introns of the Arabidopsis tryptophan pathway gene PAT1 elevates mRNA accumulation from a PAT1:beta-glucuronidase (GUS) fusion roughly 5-fold without affecting the rate of PAT1:GUS transcription. To further explore the mechanism of this intron-mediated enhancement of gene expression, we wanted to determine whether splicing or specific intron sequences were necessary. In-...
متن کاملSplicing enhancement in the yeast rp51b intron.
Splicing enhancement in higher eukaryotes has been linked to SR proteins, to U1 snRNP, and to communication between splice sites across introns or exons mediated by protein-protein interactions. It has been previously shown that, in yeast, communication mediated by RNA-RNA interactions between the two ends of introns is a basis for splicing enhancement. We designed experiments of randomization-...
متن کاملCloning, expression, and functional characterization of human cyclooxygenase-1 splicing variants: evidence for intron 1 retention.
Recently, a splicing variant of cyclooxygenase (COX)-1, arising via the retention of its intron 1, was identified in canine. It was called COX-3 and was reported to be differentially sensitive to inhibition by various nonsteroidal anti-inflammatory drugs (NSAIDs) as well as acetaminophen (Chandrasekharan et al., 2002). However, the existence of an orthologous splicing variant in human tissues h...
متن کاملBronze-2 Gene Expression and Intron Splicing Patterns in Cells and Tissues of Zea mays L.
A large fraction of the transcripts of the Bronze-2 (Bz2) gene of maize (Zea mays L.) are unspliced in purple husk tissues. The accumulation of unspliced messages could have destructive potential if the intron-bearing mRNAs are translated into aberrant proteins. Our initial studies suggested that both genetic and physiological factors may influence the degree of splicing failure. Nuclear backgr...
متن کاملIntron-3 retention/splicing controls neuronal expression of apolipoprotein E in the CNS.
Neuronal expression of apolipoprotein (apo) E4 may contribute to the pathogenesis of Alzheimer's disease (AD). In studying how apoE expression is regulated in neurons, we identified a splicing variant of apoE mRNA with intron-3 retention (apoE-I3). ApoE-I3 mRNA was detected in neuronal cell lines and primary neurons, but not in astrocytic cell lines or primary astrocytes, from humans and mice b...
