Nascent transript profiling upon in mouse embryonic stem cells under control conditions or Phf5a knockdown

ABSTRACT: Phf5a regulates transcription elongation in mouse embryonic stem cells (ESCs), through regulation of the Paf1 complex. In this study we assayed nascent RNA profiling using global run-on sequncing in mouse ESCs under conditions of self-renewal, differentiation and Phf5a knockdown. These results revealed that genes positively regulated by Paf1 in ESCs exibit RNA elongation pausing on their promoters. We used conditions of self-renewal, differentiation, Phf5a knockdown and Paf1 knockdown to monitor nascent transcript expression changes during Phf5a depletion using global run-on RNA sequencing (GRO-seq). These results revealed that Phf5a through the control of Paf1 complex regulates pause release and elongation of pluripoency-associated genes in embryonic stem cells.

Characterization of RNA Polymerase II occupancy in mouse embryonic stem cells under control conditions or Phf5a knockdown

Project description:Phf5a regulates transcription elongation in mouse embryonic stem cells (ESCs), through regulation of the Paf1 complex. In this study we assayed for genome-wide localization of Ser-5-phosphorylated RNA polymerase II and Ser-2-phosphorylated RNA polymerase II in mouse ESCs under conditions of shControl and shPhf5a knockdown. These results revealed that downregualtion of Phf5a results in the increase of the initiating form of RNA polymerase II (Ser5-phosphorylated) and in the aberrant loss of the elongating form of RNA polymerase II (Ser2-phosphorylated) of pluripotency genes in ESCs.

PAF1, a molecular regulator of promoter-proximal pausing by RNA Polymerase II

Project description:The control of promoter-proximal pausing and the release of RNA polymerase II (RNA Pol II) is a widely used mechanism for regulating gene expression in metazoans, especially for genes that respond to environmental and developmental cues. Here, we identify Pol II associated Factor 1 (PAF1) as a major regulator of promoter-proximal pausing. Knockdown of PAF1 leads to increased release of paused Pol II into gene bodies at thousands of genes. Genes with the highest levels of paused Pol II exhibit the largest redistribution of Pol II from the promoter-proximal region into the gene body in the absence of PAF1. PAF1 depletion results in increased nascent transcription and increased levels of phosphorylation of Pol II’s c-terminal domain on serine 2 (Ser2P). These changes can be explained by the recruitment of the Ser2P kinase Super Elongation Complex (SEC) effecting increased release of paused Pol II into productive elongation, thus establishing a novel function for PAF1 as a major regulator of pausing in metazoans. ChIP-seq of Pol II of different forms, SEC subunits, PAFc subunits and H2Bub in human cell lines targeted by PAF1 or scramble shRNA. ChIP-seq of total Pol II in HCT116 cells targeted by BRE1A or scramble shRNA. ChIP-seq of total Pol II in S2 cells targeted by Paf1 or LacZ RNAi. Total RNA-seq, nascent RNA-seq and GRO-seq in HCT116 cells targeted by PAF1 or scramble shRNA.

A balanced Oct4 protein interaction network is crucial for maintaining pluripotency

Project description:Oct4 is considered a master transcription factor for pluripotent cell self-renewal and embryo development. It primarily collaborates with other transcriptional factors or coregulators to maintain pluripotency. However, it is still unclear how Oct4 interacts with its partners. Here, we show that the Oct4 linker interface mediates competing and balanced Oct4 protein interactions which are crucial for maintaining pluripotency. Linker mutant ESCs maintain the key pluripotency genes expression, but show decreased expression of self-renewal genes and increased expression of differentiation genes which result in impaired ESCs self-renewal and early embryonic lethality. Linker mutation dose not affect Oct4 genomic binding and transactivation potential, but breaks the balanced Oct4 interactome. In mutant ESCs, the interaction between Oct4 and Klf5 was decreased, but interactions between Oct4 and Cbx1, Ctr9, Cdc73 were increased which disrupt the epigenetic state of ESCs. Overexpression of Klf5 or knockdown Cbx1, Cdc73 rescue the cellular phenotype of linker mutant ESCs by rebalancing Oct4 interactome indicating that different partners interact with Oct4 competitively. Thus, by showing how Oct4 interacts with different partners, we provide novel molecular insights to explain how Oct4 contributes to the maintenance of pluripotency.
