Gene expression data of human primary keratinocytes with control or DDX6 knockdown

ABSTRACT: Stem and progenitor cells maintain the tissue they reside in for life by regulating the balance between proliferation and differentiation. How this is done is not well understood. Here, we report that DDX6 is necessary for maintaining human epidermal progenitor cell self-renewal. Global gene expression profiling using U133 plus 2.0 arrays were used to deteremine the genes perturbed by knockdown of DDX6.

Gene expression data of human keratinocytes knocked down for SMC1A, SMC3, or control shRNA.

Project description:The purpose of the study is to understand the impacts of cohesin knockdown on epidermal gene expression. Primary human keratinocytes were knocked down for SMC1A, SMC3, or control to determine its genome-wide gene expression profile. Global gene expression profiling using U133 plus 2.0 arrays were used to deteremine the genes perturbed by knockdown of SMC1A or SMC3.

Gene expression data of human primary keratinocytes with control, EXOSC9 or EXOSC9+GRHL3 knockdown

Project description:Stem and progenitor cells maintain the tissue they reside in for life by regulating the balance between proliferation and differentiation. How this is done is not well understood. Here, we report that the human exosome maintains progenitor cell function. The expression of several subunits of the exosome were found to be enriched in epidermal progenitor cells, which were required to retain proliferative capacity and to prevent premature differentiation. Loss of PM/Scl-75 also known as EXOSC9, a key subunit of the exosome complex, resulted in loss of cells from the progenitor cell compartment, premature differentiation, and loss of epidermal tissue. EXOSC9 promotes self-renewal and prevents premature differentiation by maintaining transcript levels of a transcription factor necessary for epidermal differentiation, GRHL3, at low levels through mRNA degradation. These data demonstrate that control of differentiation specific transcription factors through mRNA degradation is required for progenitor cell maintenance in mammalian tissue. Refer to publication (Mistry et. Cell Stem Cell 2012) for more detail For gene expression profiling, cultured primary human keratinocytes were knocked down for EXOSC9, EXOSC9 and GRHL3, or control. RNA was harvested from the cells 5 days after knockdown. Microarray analysis using Affymetrix HG-U133 2.0 plus arrays was performed on duplicate samples. Significantly changed genes were identified as previously described(Sen et al., 2010).

RNA-seq of coding RNA from DDX6 knockout human haploid (HAP1) cells

Project description:We performed a genome-scale screen for suppressors of interferon stimulated gene (ISG) expression in human haploid cells (HAP1). DEAD-box helicase 6 (DDX6) was a significant hit. In order to validate DDX6 as a regulator of ISG expression, we created knockouts of DDX6 in HAP1 cells using CRISPR-Cas9 and performed RNA-seq on coding RNA from DDX6 KO and WT cells. This data was used to determine if ISGs were upregulated in DDX6 KO HAP1 cells.

Gene expression data of regenerated human epidermis overexpressing control LACZ or SOX2

Project description:SOX2 is not expressed in normal human epidermis but its expression is elevated in pre-neoplastic epidermis suggesting that it may have a role in the tumorigenesis process. The goal of this study is to determine the impacts of SOX2 overexpression in regenerated human epidermis. Global gene expression profiling using U133 plus 2.0 arrays were used to deteremine the genes perturbed by overexpression of SOX2.

Large-scale study of total and polysomial mRNA after DDX6 depletion in HEK293 cells

Project description:DDX6 is an abundant cytoplasmic DEAD-box RNA helicase which is involved in disparate aspects of mRNA stability and translation, leading to a confused understanding of its global function. We carried out a large-scale study of total and polysomial mRNA after DDX6 depletion to get an accurate picture of its roles in human cells.

mRNA transcriptome analysis of Ddx6 knockout embryos

Project description:DDX6 is an RNA helicase and involved in various post-transcriptional regulatory processes. Although DDX6 is an evolutionarily well conserved central player in post-transcriptional gene regulation, its function in embryonic development remains obscure. To study this, we examined Ddx6 knockout mouse embryos and pluripotent cell lines. E8.5 Ddx6 mutants exhibited gastrulation defects. To transcriptomically identify the existing cell population in E8.5 mutant embryos and further find the possible causes of this defect, we performed RNA-seq analysis with E8.5 embryo cDNA libraries.

The RNA helicase DDX6 regulates self-renewal and differentiation of human and mouse stem cells [RNA-seq2]

Project description:Post-transcriptional mechanisms have the potential to influence complex changes in gene expression, yet their role in cell fate transitions remain largely unexplored. Here, we show that the RNA helicase DDX6 is crucial for the dissolution of the pluripotency-specific transcriptional network in mouse and human embryonic stem cells (ESCs). We further demonstrate that epigenetic silencing of DDX6 endows primed ESCs with a differentiation-resistant, “hyper-pluripotent” state, which readily reprograms to a naïve state resembling the preimplantation embryo. In addition to directing cell fate in ESCs, we find that DDX6 plays a key role in adult progenitors where it controls the balance between self-renewal and differentiation in a context-dependent manner. Specifically, DDX6 loss blocks the differentiation of mouse intestinal stem cells and human neural stem cells, while it favors exit from the progenitor state in human muscle and mesenchymal progenitors. Mechanistically, we show that DDX6 coordinates the storage and translational suppression of target mRNAs in P-bodies. Upon loss of DDX6 or mutation of its helicase domain, P-bodies dissolve and release mRNAs encoding fate-instructive transcription and chromatin factors that subsequently re-enter the ribosome pool. Increased translation of these targets impacts cell fate by rewiring the enhancer, heterochromatin and DNA methylation landscapes of human undifferentiated cell types. Collectively, our data establish a novel link between P-body homeostasis, chromatin organization and cellular potency across diverse stem and progenitor cell populations.
