MetabolomicsDissection of two routes to naïve pluripotency using different kinase inhibitors
Embryonic stem cells (ESCs) can be maintained in the naïve state through inhibition of Mek1/2 and Gsk3 (2i). A relevant effect of 2i is the inhibition of Cdk8/19, which are negative regulators of the Mediator complex, responsible for the activity of enhancers. Inhibition of Cdk8/19 (Cdk8/19i) stimul...

TranscriptomicsGlobal Run-On sequencing (GRO-seq) of HeLa cells under CDK9 inhibitor tratment to study elongation checkpoints at both ends of RNA polymerase II-transcribed genes.
Global Run-On sequencing (GRO-seq) was carried out on nuclei isolated from HeLa cells after 30 minutes of treatment with CDK9 inhibitors KM05382 and DRB and from two untreated controls. Libraries of nascent RNAs were generated and sequenced using Illumina Hi-seq technology. GRO-seq reads were proces...

TranscriptomicsDSIF and RNA polymerase II CTD Phosphorylation Coordinate the Recruitment of Rpd3S to Actively Transcribed Genes
Histone deacetylase Rpd3 is part of two distinct complexes: the large (Rpd3L) and small (Rpd3S) complexes. While Rpd3L targets specific promoters for gene repression, Rpd3S is recruited to ORFs to deacetylate histones in the wake of RNA polymerase II, to prevent cryptic initiation within genes. Meth...

GenomicsIdentification of the primary target of the chemotherapeutic agent CX-5461 as a late step in transcription initiation by RNA Polymerase I
In recent years, several small molecule cytotoxic drugs have been identified as potential inhibitors of ribosome biogenesis (Drygin et al., 2011; Peltonen et al., 2014a; Peltonen et al., 2014b). CX-5461 is one such drug that has also demonstrated anticancer potential for a wide range of malignancies...

TranscriptomicsRegulating RNA Polymerase Pausing and Elongation in Embryonic Stem Cell Transcription
Transitions between pluripotent stem cells and differentiated cells are executed by key transcription regulators. Comparative measurements of RNA polymerase distribution over the genomeM-bM-^@M-^Ys primary transcription units in different cell states can identify the genes and steps in the transcrip...

GenomicsChIP-Seq of ERalpha and RNA polymerase II defines genes differentially responding to ligands
We used ChIP-Seq to map ERalpha binding sites and to profile changes in RNA polymerase II (RNAPII) occupancy in MCF-7 cells in response to estradiol (E2), tamoxifen or fulvestrant. We identified 10,205 high confidence ERalpha binding sites in response to E2 of which 68% contained an estrogen respons...

TranscriptomicsUsing GRO-seq experiments to determine the mechanism of C. elegans dosage compensation's control of transcription
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...

TranscriptomicsIntroducing synthetic thermostable RNase inhibitors in single-cell RNA-seq
Single-cell RNA-sequencing (scRNAseq) is revolutionizing biomedicine, propelled by advances in methodology, ease of use, and cost reduction of library preparation. Over the past decade, there have been remarkable technical improvements in most aspects of single-cell transcriptomics. Yet, there has b...
