Breaking barriers to transcription elongation

A Saunders, LJ Core, JT Lis - Nature reviews Molecular cell biology, 2006 - nature.com
Hundreds of protein factors participate in transcription and its regulation in eukaryotes. Many
of these proteins regulate specific genes by targeting upstream promoter regions, whereas …

Divergent transcription: a new feature of active promoters

AC Seila, LJ Core, JT Lis, PA Sharp - Cell cycle, 2009 - Taylor & Francis
Divergent transcription is common of many promoters in organisms as diverse as mammals
and yeast. Many independent experiments indicate that RNA polymerase II is frequently …

Nascent RNA sequencing reveals widespread pausing and divergent initiation at human promoters

LJ Core, JJ Waterfall, JT Lis - Science, 2008 - science.org
RNA polymerases are highly regulated molecular machines. We present a method (global
run-on sequencing, GRO-seq) that maps the position, amount, and orientation of …

Precise maps of RNA polymerase reveal how promoters direct initiation and pausing

H Kwak, NJ Fuda, LJ Core, JT Lis - Science, 2013 - science.org
Transcription regulation occurs frequently through promoter-associated pausing of RNA
polymerase II (Pol II). We developed a precision nuclear run-on and sequencing (PRO-seq) …

Analysis of nascent RNA identifies a unified architecture of initiation regions at mammalian promoters and enhancers

LJ Core, AL Martins, CG Danko, CT Waters, A Siepel… - Nature …, 2014 - nature.com
Despite the conventional distinction between them, promoters and enhancers share many
features in mammals, including divergent transcription and similar modes of transcription …

From telomere to telomere: The transcriptional and epigenetic state of human repeat elements

…, LJ Core, JL Gerton, W Makalowski, D Olson, J Rosen… - Science, 2022 - science.org
Mobile elements and repetitive genomic regions are sources of lineage-specific genomic
innovation and uniquely fingerprint individual genomes. Comprehensive analyses of such …

Transcription regulation through promoter-proximal pausing of RNA polymerase II

LJ Core, JT Lis - Science, 2008 - science.org
Recent work has shown that the RNA polymerase II enzyme pauses at a promoter-proximal
site of many genes in Drosophila and mammals. This rate-limiting step occurs after …

Base-pair-resolution genome-wide mapping of active RNA polymerases using precision nuclear run-on (PRO-seq)

…, CG Danko, RK Patel, CT Waters, K Munson, LJ Core… - Nature protocols, 2016 - nature.com
We provide a protocol for precision nuclear run-on sequencing (PRO-seq) and its variant,
PRO-cap, which map the location of active RNA polymerases (PRO-seq) or transcription start …

Coordinated effects of sequence variation on DNA binding, chromatin structure, and transcription

…, I Padioleau, G Udin, S Thurnheer, D Hacker, LJ Core… - Science, 2013 - science.org
DNA sequence variation has been associated with quantitative changes in molecular
phenotypes such as gene expression, but its impact on chromatin states is poorly characterized. …

Regulating RNA polymerase pausing and transcription elongation in embryonic stem cells

…, LJ Core, RJ Munroe, J Schimenti… - Genes & …, 2011 - genesdev.cshlp.org
Transitions between pluripotent stem cells and differentiated cells are executed by key
transcription regulators. Comparative measurements of RNA polymerase distribution over the …
