Enhancers regulate dynamic gene expression in a spatiotemporal specific manner. A number of positive as well as negative regulators of enhancers have been reported so far. However, whether and how these regulators sense enhancer activity dynamics remains unclear. In this study, we show that a specific enhancer regulator, RACK7, swiftly re-distributes from repressed enhancers to activated enhancers in response to a plethora of acute stimulations. We further show that this process depends on trans ...[more]

Project description:Enhancers regulate dynamic gene expression in a spatiotemporal specific manner. A number of positive as well as negative regulators of enhancers have been reported so far. However, whether and how these regulators sense enhancer activity dynamics remains unclear. In this study, we show that a specific enhancer regulator, RACK7, swiftly re-distributes from repressed enhancers to activated enhancers in response to a plethora of acute stimulations. We further show that this process depends on transcription and RACK7 positively regulates enhancer activation by promoting the recruitment of RNA polymerase II. Taken together, our findings suggest that RACK7 senses enhancer activity changes and facilitates their activation during acute stimulations.

FOXO3 selectively amplifies enhancer activity to establish target gene regulation.

Project description:Forkhead Box O (FOXO) transcription factors are versatile players in diverse cellular processes, affecting tumorigenesis, metabolism, stem cell maintenance and lifespan. To understand the transcriptional output of FOXO3 activation, we investigate features that define the subset of enhancer binding events that actually contribute to gene regulation. We show FOXO3 transcriptional output is determined by the amount of bound FOXO3, which in turn is determined by motif presence, pre-existing enhancer activity and accessibility. In this manner, FOXO3 amplifies pre-existing levels of activity marks and potentiates enhancer RNA transcription. We conclude that not only enhancer presence and sequence content, but also the pre-existing activity dictates FOXO3 binding and transcriptional output. Considering the flexible and cell type specific nature of regulatory regions and their activity, our observations provide a novel explanation for the diversity in FOXO transcriptional programs and introduce chromatin context as a new player in the regulation of FOXO activity in ageing and disease.

Genome-wide control of RNA polymerase II activity by cohesin (sequencing)

Project description: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 chromatid cohesion. To clarify cohesin’s roles in transcription, we measured how cohesin controls RNA polymerase II (Pol II) activity by genome-wide chromatin immunoprecipitation and precision global run-on sequencing. On average, cohesin-binding genes have more transcriptionally active Pol II and promoter-proximal Pol II pausing than non-binding genes, and are more efficient, producing higher steady state levels of mRNA per transcribing Pol II complex. Cohesin depletion frequently increases pausing at cohesin-binding genes, indicating that cohesin often facilitates transition of paused Pol II to elongation. In many cases this likely reflects a role for cohesin in transcriptional enhancer function. Strikingly, more than 95% of predicted extragenic enhancers bind cohesin, and cohesin depletion can reduce their association with Pol II, indicating that cohesin facilitates enhancer-promoter contact. Cohesin directly promotes transcription of the myc gene, and cohesin depletion reduces Pol II activity at most Myc target genes. The multiple transcriptional roles of cohesin revealed by these studies likely underlie the growth and developmental deficits caused by minor changes in cohesin activity. The PRO-seq method was used to measure transcriptionally engaged Pol II genome-wide in two replicates each of mock RNAi-treated, Nipped-B RNAi-treated, and Rad21 RNAi-treated ML-DmBG3-c2 cells.

Genome-wide control of RNA polymerase II activity by cohesin (tiling)

The multiple transcriptional roles of cohesin revealed by these studies likely underlie the growth and developmental deficits caused by minor changes in cohesin activity. We performed ChIP-chip of Rpb3 (representing total Pol II), Ser2P-Pol II (representing elongating Pol II), and Cdk12 and CycT Pol II kinase components in Mock RNAi-treated and cohesin subunit Rad21 RNAi-treated ML-DmBG3-c2 cells, which revealed that cohesin depletion has a variety of effects on Pol II occupancy and modification, as well as on occupancy of Pol II kinases.
