Functional and Mechanistic Studies of XPC DNA-Repair Complex as Transcriptional Coactivator in Embryonic Stem Cells

ABSTRACT: We recently identified the DNA repair complex XPC-RAD23B-CETN2 as a stem cell coactivator (SCC) required for OCT4 and SOX2 transcriptional activation. Here we investigate genome-wide the role of SCC in murine ESCs by mapping regions bound by its RAD23B subunit in wild type and Xpc-/- ESCs, and analyzing transcriptional profiles of SCC-depleted ESCs. RAD23B ChIP-seq in wild type murine ESCs was performed in two replicates; normal IgG were used as controls. RAD23B ChIP-seq in Xpc-/- mESCs was compared to normal IgG. Antibodies to immunoprecipitate RAD23B were raised in guinea pigs against the 108-177 peptide of murine RAD23B protein (NP_033037). Anti-sera were affinity-purified. For RNA-seq, we compared wild type JM8.N4 cells with either Rad23b-/- cells, Rad23b-/-Xpc KD1 or Rad23b-/-Xpc KD2 cells. Xpc was knocked down with two independent shRNAs (KD1 and KD2).

Combining transcriptome and proteome analysis to identify and characterize the RpoS regulon in Pseudomonas fluorescens

Project description:Background: Microorganisms are the major cause of food spoilage during storage, processing and distribution. Pseudomonas fluorescens is a typical spoilage bacterium that contributes to a large extent to the spoilage process of proteinaceous food. RpoS is considered an important global regulator involved in stress survival and virulence in many pathogens. Our previous work revealed that RpoS contributed to the spoilage activities of P. fluorescens by regulating resistance to different stress conditions, extracellular acylated homoserine lactone (AHL) levels, extracellular protease and total volatile basic nitrogen (TVB-N) production. However, RpoS-dependent genes in P. fluorescens remained undefined. Results: RNA-seq transcriptomics analysis combined with quantitative proteomics analysis basing on multiplexed isobaric tandem mass tag (TMT) labeling was performed for the P. fluorescens wild-type strain UK4 and its derivative carrying a rpoS mutation. A total of 375 differentially expressed genes (DEGs) and 212 differentially expressed proteins (DEPs) were identified in these two backgrounds. The DGEs were further verified by qRT-PCR tests, and the genes directly regulated by RpoS were confirmed by 5’-RACE-PCR sequencing. The combining transcriptome and proteome analysis revealed a role of this regulator in several cellular processes, including polysaccharide metabolism, intracellular secretion and extracellular structures, cell well biogenesis, stress responses, ammonia and biogenic amine production, which may contribute to biofilm formation, stress resistance and spoilage activities of P. fluorescens. Moreover, in this work we indeed observed that RpoS contributed to the production of the macrocolony biofilm’s matrix.

Nucleoporin Nup153 Regulates Stem Cell Pluripotency through Gene Silencing

Project description:Nucleoporins (Nups) are a family of proteins best known as the constituent building blocks of nuclear pore complexes (NPCs), the transport channels that mediate nuclear transport. Recent evidence suggest that several Nups have additional roles in controlling the activation and silencing of developmental genes, however, the mechanistic details of these functions remain poorly understood. Here, we show that depletion of Nup153 in mouse embryonic stem cells (mESCs) causes the de-repression of developmental genes and induction of early differentiation. This loss of pluripotency is not associated with defects in global nucleo-cytoplasmic transport activity. Instead, Nup153 binds to the transcriptional start site (TSS) of developmental genes and mediates the recruitment of the polycomb repressive complex 1 (PRC1) to its target loci. Our results reveal a nuclear transport-independent role of Nup153 in maintaining stem cell pluripotency and introduce a role of NPC proteins in mammalian epigenetic gene silencing.

Regulation of Promoter and Enhancer Histone Landscape by DNA Methylation in Embryonic Stem Cells (ChIP-seq)

Project description:In this study, we mapped modification of lysine 4 and lysine 27 of histone H3 genome-wide in a series of mouse embryonic stem cells (mESCs) varying in DNA methylation levels based on knock-out and reconstitution of DNA methyltransferases (DNMTs). We extend previous studies showing cross-talk between DNA methylation and histone modifications by examining a breadth of histone modifications, causal relationships, and direct effects. Our data shows a causal regulation of H3K27me3 at gene promoters as well as H3K27ac and H3K27me3 at tissue-specific enhancers. We also identify isoform differences between DNMT family members. This study provides a comprehensive resource for the study of the complex interplay between DNA methylation and histone modification landscape. Histone ChIP-seq of H3K4me3, H3K27me3, H3K4me1, and H3K27ac were performed on wild-type, Dnmt triple knock-out (Dnmt1/3a/3b; TKO), Dnmt double knock-out (Dnmt3a/3b; DKO), and respective reconstitution mouse embryonic stem cell lines

The heme-responsive PrrH sRNA regulates Pseudomonas aeruginosa pyochelin gene expression

Project description:Pseudomonas aeruginosa is an opportunistic pathogen that requires iron for growth and virulence, yet this nutrient is sequestered by the innate immune system during infection. When iron is limiting, P. aeruginosa expresses the PrrF1 and PrrF2 small regulatory RNAs (sRNAs), which post-transcriptionally repress expression of non-essential iron-containing proteins thus sparing this nutrient for more critical processes.The genes for the PrrF1 and PrrF2 sRNAs are arranged in tandem on the chromosome, allowing for the transcription of a longer heme-responsive sRNA, termed PrrH. While the functions of PrrF1 and PrrF2 have been studied extensively, the role of PrrH in P. aeruginosa physiology and virulence is not well understood. In this study, we performed transcriptomic and proteomic studies to identify the PrrH regulon.

Tex10 Coordinates Epigenetic Control of Super-Enhancer Activity for Pluripotency and Reprogramming [ChIP-Seq]

Project description:Super-enhancers (SEs) are large clusters of transcriptional enhancers that are co-occupied by multiple lineage specific transcription factors driving expression of genes that define cell identity. In embryonic stem cells (ESCs), SEs are highly enriched for Oct4, Sox2, and Nanog in the enhanceosome assembly and express enhancer RNAs (eRNAs). We sought to dissect the molecular control mechanism of SE activity and eRNA transcription for pluripotency and reprogramming. Starting from a protein interaction network surrounding Sox2, a key pluripotency and reprogramming factor that guides the ESC-specific enhanceosome assembly and orchestrates the hierarchical transcriptional activation during the final stage of reprogramming, we discovered Tex10 as a novel pluripotency factor that is evolutionally conserved and functionally significant in ESC self-renewal, early embryo development, and reprogramming. Tex10 is enriched at SEs in a Sox2-dependent manner and coordinates histone acetylation and DNA demethylation of SEs. Our study sheds new light on epigenetic control of SE activity for cell fate determination. Genome binding/occupancy profiling of Tex10 was performed in mouse embryonic stem cells by ChIP sequencing.

The C-terminal region of Xpc is dispensable for the transcriptional activity of Oct3/4 in mouse embryonic stem cells

Project description:The transcription factor Oct3/4 is essential to maintain pluripotency in mouse embryonic stem (ES) cells. It was reported that the Xpc DNA repair complex is involved in this process. Here we examined the role of Xpc on the transcriptional activation of the target genes by Oct3/4 using the inducible knockout strategy. We found that the removal of the C-terminal region of Xpc, including the interaction sites with Rad23 and Cetn2, showed faint impact on the gene expression profile of ES cells and the functional Xpc-ΔC ES cell lines retained proper gene expression profile as well as pluripotency to contribute chimeric embryos. These data indicated that the C-terminal region of Xpc is dispensable for the transcriptional activity of Oct3/4 in mouse ES cells. An inducible knockout ES cell line of Xpc with the Cre-loxP system was generated and gene expression was measured without Xpc deletion, after 4 days of Xpc deletion or constitutive knocked out cells. Each sample was prepared in triplicate.

Global analysis of Upf1 in mESCs reveals expanded scope of nonsense-mediated mRNA decay

Project description:Nonsense-mediated mRNA decay (NMD) is a conserved RNA surveillance pathway that is an important modulator of disease pathology and is required for embryonic development. Despite significant research effort, the rules that govern NMD remain incompletely understood. Here we used a combined¬ approach, integrating RNA-Seq, ribosome footprinting, and CLIP-Seq analysis of the essential NMD factor Upf1, to provide a more complete picture of the role of NMD in modulating gene expression in murine embryonic stem cells (mESCs). We show that presence of an exon-exon junction ?50 nucleotides (nt) downstream of a termination codon (dEJ) contributes to NMD independently of 3' UTR length, but has stronger effects in genes with shorter 3' UTRs. We also map translated upstream open reading frames (uORFs) in mESCs and show that they are associated with NMD regulation, especially of genes encoding transcription factors, and we find that lowly translated mRNAs can escape NMD. Finally, we identify over 200 direct binding targets of Upf1 and describe a pathway of Upf1-dependent gene regulation reliant on Upf1 binding to the 3' UTR and independent of presence of a dEJ. Together, these analyses characterize known and discover novel determinants of NMD and establish a broader role in mESC gene regulation for Upf1. mRNA-Seq analysis of wildtype (2 samples), translationally inhibited (by cycloheximide treatment, 2 samples), control-depleted (2 samples), and Upf1-depleted (4 samples) mouse embryonic stem cells (mESCs); CLIP-Seq analysis of Upf1 (5 samples, and 5 samples of IgG control CLIP-Seq); Ribosome footprint profiling of wildtype (1 sample), control-depleted (1 sample), and Upf1-depleted (1 sample) mESCs
