Project description:Dinocras cephalotes (large dark stonefly), genomic and transcriptomic data
| PRJEB88767 | ENA
Project description:Most of the human genome is thought to be non-functional, and includes large segments often referred to as “dark matter” DNA. The genome also encodes hundreds of putative and poorly characterized transcription factors (TFs). We determined genomic binding locations of 166 uncharacterized human TFs in living cells. Nearly half of them associated strongly with known regulatory regions such as promoters and enhancers, often at conserved motif matches and co-localizing with each other. Surprisingly, the other half often associated with genomic dark matter, at largely unique sites, via intrinsic sequence recognition. Dozens of these, which we term “Dark TFs” mainly bind within regions of closed chromatin. Dark TF binding sites are rarely under purifying selection, and are enriched for transposable elements. Many Dark TFs are KZNFs, which contain the repressive KRAB domain, but many are not, and may represent potential pioneer TFs: based on compiled literature information, the Dark TFs exert diverse functions ranging from early development to tumor suppression. Thus, a large fraction of previously uncharacterized human TFs may have unappreciated activities within the dark matter genome.

Project description:In the unicellular cyanobacterium, Synechococcus elongatus PCC 7942, dramatically reduces the transcription rate in the dark (dark repression), and its cellular functions enormously depend on light as an energy source through photosynthetic activity. Here, we employed high-density oligonucleotide arrays to investigate comprehensive profiles of genome-wide Synechococcus gene expression when illuminated or dark-acclimated cells are treated with photosynthesis inhibitors DCMU or DBMIB. In addition, we added rifampicin to the DBMIB-treated cells in the dark, and analyzed genome-wide expression profiles. Treatment with DCMU or DBMIB under illuminated condition mimicked dark-repression-like genome-wide transcription profiles. Addition of DBMIB under dark condition largely attenuated dark-repression and kept relatively large amount of transcripts, this high-transcripts level still kept when rifampicin was additionally administered.
