Personalized medicine is expected to benefit from combining genomic information with regular monitoring of physiological states by multiple high-throughput methods. Here, we present an integrative personal omics profile (iPOP), an analysis that combines genomic, transcriptomic, proteomic, metabolomic, and autoantibody profiles from a single individual over(More)
We have previously shown that specific nuclear pre-mRNA transcripts and their splicing products, as well as the general population of nuclear poly(A)+ RNA, are packaged in large nuclear ribonucleoprotein (InRNP) particles that sediment at the 200S region in sucrose gradients. The InRNP particles contain all uridine-rich small nuclear ribonucleoprotein(More)
Pre-mRNA splicing involves recognition of a consensus sequence at the 5' splice site (SS). However, only some of the many potential sites that conform to the consensus are true ones, whereas the majority remain silent and are not normally used for splicing. We noticed that in most cases the utilization of such a latent intronic 5' SS for splicing would(More)
In previous studies we have shown that specific nuclear pre-mRNAs and their splicing products, as well as the general population of nuclear poly(A)+ RNA, are found packaged in 200 S large nuclear ribonucleoprotein (lnRNP) particles that represent the splicing machinery in vivo. The lnRNP particles contain all U small nuclear ribonucleoproteins (snRNPs)(More)
One of the major forms of alternative splicing, which generates multiple mRNA isoforms differing in the precise combinations of their exon sequences, is exon skipping. While in constitutive splicing all exons are included, in the skipped pattern(s) one or more exons are skipped. The regulation of this process is still not well understood; so far, cis-(More)
The effect of heat shock on the packaging and splicing of nuclear CAD pre-mRNA, a transcript expressed constitutively from a non heat-inducible promoter, was studied in vivo in Syrian hamster cells. While mild heat shock did not affect significantly the packaging of CAD RNA in 200S InRNP particles, it caused perturbation to splicing. First, the heat shock(More)
RNA sequences that conform to the consensus sequence of 5' splice sites but are not used for splicing occur frequently in protein coding genes. Mutational analyses have shown that suppression of splicing at such latent sites may be dictated by the necessity to maintain an open reading frame in the mRNA. Here we show that stop codon frequency in introns(More)
Splice site selection is a key element of pre-mRNA splicing and involves specific recognition of consensus sequences at the 5(') and 3(') splice sites. Evidently, the compliance of a given sequence with the consensus 5(') splice site sequence is not sufficient to define it as a functional 5(') splice site, because not all sequences that conform with the(More)
Cytochrome b5/cytochrome b5 reductase (cb5/cb5r) is a cytosolic fusion protein between the hemoprotein cytochrome b5 and the flavoprotein cytochrome b5 reductase. We describe the identification and characterization of a novel splice variant of cb5/cb5r in the mouse and rat and show that expression of the variant is conserved in both species but is not(More)
