Background: Gene expression microarrays have provided many insights into changes in gene expression patterns between different tissue types, developmental stages, and disease states. Analyses of these data focused primarily measuring the relative abundance of transcripts of a gene, while treating most or all transcript isoforms as equivalent. Differences in the selection between transcript isoforms can, however, represent critical changes to either the protein product or the posttranscriptional regulation of the transcript.

SL1 leaders are spliced mostly to pre-mRNAs from genes with outrons, intron-like sequences at the 5'-ends of the pre-mRNAs. In contrast, SL2 leaders are nearly exclusively trans-spliced to genes that occur downstream in polycistronic pre-mRNAs produced from operons.

- * A significant genetic inversion on chromosome 6 was found in C3H/HeJ that also affects the 6T strain, leading to notable decreases in gene expression related to bone density and fat accumulation.
- * The creation of a new congenic strain (B.H-6) showed that the inherited genetic inversion in 6T does not solely account for its low bone volume phenotype, suggesting that genomic
Background: The Cleavage Stimulation Factor (CstF) is a required protein complex for eukaryotic mRNA 3'-processing. CstF interacts with 3'-processing downstream elements (DSEs) through its 64-kDa subunit, CstF-64; however, the exact nature of this interaction has remained unclear. We used EST-to-genome alignments to identify and extract large sets of putative 3'-processing sites for mRNA from ten metazoan species, including Homo sapiens, Canis familiaris, Rattus norvegicus, Mus musculus, Gallus gallus, Danio rerio, Takifugu rubripes, Drosophila melanogaster, Anopheles gambiae, and Caenorhabditis elegans.

Sites have been identified primarily via expressed sequence tag-genome alignments, enabling delineation of both the specificities and heterogeneity of 3'-processing events.
