Global analysis of expression upon RNA Pol I inhibition (iPol I) in ESCs

Project description:Immediately following fertilisation, the genomes of mammalian embryos undergo extensive reprogramming to generate a totipotent zygote with the capacity to form the entire developing organism and associated extraembryonic tissues. The embryo must also switch from dependence on maternal transcripts to transcribing from its own genome, and is accompanied in mice by rapid and transient upregulation of MERVL transposons and MERVL-driven genes at the 2-cell stage. The mechanisms and requirement for MERVL and 2-cell (2C) gene upregulation are poorly understood. Moreover, this program must be rapidly shut off upon 2C exit and developmental progression. Here, we report that robust ribosomal RNA synthesis and nucleolar integrity are essential for exit from the 2C state. 2-cell embryos and 2C-like cells show immature nucleoli with altered structure and reduced function, and we reveal that nucleolar disruption induces conversion to the 2C-like state in ESCs. Mechanistically, the 2C/MERVL activator Dux is held in perinucleolar chromatin in ESCs and released into the nucleoplasm upon nucleolar disruption or direct inhibition of nucleolar phase separation, leading to its rapid upregulation. In embryos, nucleolar disruption prevents proper Dux silencing and leads to 2-4 cell arrest. Our findings reveal an intriguing link between rRNA synthesis, nucleolar maturation and gene repression during early development.

Hog1 controls global reallocation of RNA Pol II upon osmotic shock

Project description:When challenged with osmotic shock, S. cerevisiae induces hundreds of genes, despite a global reduction in transcriptional capacity. The mechanisms that regulate this rapid reallocation of transcriptional resources are not known. Here we show that redistribution of RNA Pol II upon stress requires the stress-responsive MAP kinase Hog1. We find that Hog1 and RNA Pol II co-localize to open reading frames that bypass global transcriptional repression, and that these targets are specified by two osmotic stress-responsive transcription factors. The combination of reduced global transcription with a gene-specific override mechanism allows cells to rapidly switch their transcriptional program in response to stress.

A global transcriptome analysis of human epidermal keratinocytes upon inhibition of lncRNA WAKMAR1

Project description:Recent study has revealed that long non-coding RNAs (lncRNAs) perform as important regulators of cellular physiology and pathology, which makes them promising therapeutic and diagnostic entities. We found lncRNA WAKMAR1 is significantly down-regulated in wound-edge keratinocytes from venous ulcer and diabetic foot ulcer compared to the normal wounds. To study the genes regulated by WAKMAR1, we transfected lncRNA GapmeRs into human primary epidermal keratinocytes to inhibit its expression. We performed a global transcriptome analysis of keratinocytes upon inhibition of WAKMAR1 using Affymetrix arrays. We performed a global transcriptome analysis of keratinocytes upon inhibition of WAKMAR1 using Affymetrix arrays.
