TranscriptomicsEvolutionary dynamics of gene and isoform regulation in mammalian tissues
Most mammalian genes produce multiple distinct mRNAs through alternative splicing, but the extent of splicing conservation is not clear.  To assess tissue-specific transcriptome variation across mammals, we sequenced cDNA from 9 tissues from 4 mammals and one bird in biological triplicate, at unprec...

TranscriptomicsAn EMT-driven alternative splicing program occurs in human breast cancer and modulates cellular phenotype.
Regulation of cell-cell junction formation and regulation of cell migration were enriched among EMT (Epithelial-Mesenchymal Transition)-associated alternatively splicing events. Our analysis suggested that most EMT-associated alternative splicing events are regulated by one or more members of the RB...

TranscriptomicsPromoter directionality is controlled by U1 snRNP and polyadenylation signals
Transcription of the mammalian genome is pervasive, but productive transcription outside of protein-coding genes is limited by unknown mechanisms. In particular, although RNA polymerase II (RNAPII) initiates divergently from most active gene promoters, productive elongation occurs primarily in the s...

TranscriptomicsExon array analysis of resting and activated primary murine CD4+ T-cells
The stability, localization and translation of mammalian mRNAs are largely determined by sequences in the 3' untranslated region (UTR). Here, we describe a conserved program of increased upstream polyadenylation site usage following activation of primary murine CD4+ T lymphocytes. This program, re...

TranscriptomicsPromoter proximal pausing and its regulation by c-Myc in embryonic stem cells: ChIP-chip
Recruitment of the RNA Polymerase II (Pol II) transcription initiation apparatus to promoters by specific DNA binding transcription factors is well recognized as a key regulatory step in gene expression. We describe here evidence that promoter-proximal pausing is a general feature of transcription ...

TranscriptomicsSR Proteins Collaborate with 7SK and Promoter-Associated Nascent RNA to Release Paused Polymerase
RNAP II is frequently paused near gene promoters in mammals and its transition to productive elongation requires active recruitment of P-TEFb, a cyclin-dependent kinase for RNAP II and other key transcription elongation factors. A fraction of P-TEFb is sequestered in an inhibitory complex containing...
