TranscriptomicsDevelopment of GRO-cap (GRO-seq followed by 5'-cap enrichment) to map transcription start sites in C. elegans
Dosage Compensation is required to correct for uneven gene dose between the sexes. We utilized global run-on sequencing (GRO-seq) to examine how Caenorhabditis elegans dosage compensation reduces transcription of X-linked genes. To facilitate these experiments, we required accurate 5M-bM-^@M-^Y-ends...

TranscriptomicsNascent RNA sequencing reveals widespread pausing and divergent initiation at human promoters
RNA polymerases are highly regulated molecular machines. We present a method (GRO-seq) that maps the position, amount, and orientation of transcriptionally-engaged RNA polymerases genome-wide. In this method, nuclear run-on RNAs are subjected to large-scale parallel sequencing and mapped to the gen...

GenomicsGAGA Factor maintains promoters in nucleosome-free conformation and allows promoter-proximal pausing [MNase]
Promoter-proximal pausing of RNA polymerase II (Pol II) is a widespread in higher eukaryotes. Previous studies have shown that GAF is enriched at paused genes, but the role of GAF in pausing has not been well characterized on a genome-wide level. To investigate the role of GAF in pausing, we RNAi-de...

TranscriptomicsGlobal Analysis of the Immediate Transcriptional Effects of Estrogen Signaling Reveals a Rapid, Extensive, and Transient Response
We report the immediate effects of estrogen signaling on the transcriptome of breast cancer cells using Global Run-On and sequencing (GRO-seq). We found that estrogen signaling directly regulates a strikingly large fraction of the transcriptome in a rapid, robust, and unexpectedly transient manner. ...

TranscriptomicsGenome-wide control of RNA polymerase II activity by cohesin (sequencing)
Cohesin is a well-known mediator of sister chromatid cohesion, but it also influences gene expression and development. These non-canonical roles of cohesin are not well understood, but are vital: gene expression and development are altered by modest changes in cohesin function that do not disrupt ch...

TranscriptomicsSignaling Pathways Deferentially Affect RNA Polymerase II Initiation, Pausing, and Elongation in Human Cells: TNF-alpha dependent signaling in AC16 cells
We used Global Run-on and Sequencing (GRO-seq) to measure the rate of transcription elongation by RNA polymerase II (Pol II) following gene activation. We observed that Pol II elongation rates can vary as much as 4-fold at different genomic loci and in response to two distinct cellular signaling pa...

TranscriptomicsX chromosome dosage compensation via enhanced transcriptional elongation in Drosophila males (Untreated)
MSL (Male-specific lethal) complex increases transcription on the single X chromosome of Drosophila males in order to equalize expression of X-linked genes between males (XY) and females (XX). The increase in transcript levels correlates with MSL- dependent acetylation of histone H4 at K16 within th...
