Positive DNA helical stress accumulates in vivo by the unbalanced relaxation of positive and negative DNA supercoils in M-NM-^Ttop1, top2ts, pGPD:TopA yeast cells. The resulting overwinding of DNA greatly diminishes overall RNA synthesis. Here we show that whereas most genes reduce their transcript ...
ORGANISM(S): Saccharomyces cerevisiae 
We have mapped the binding sites for the five key regulators GATA1, GATA2, RUNX1, FLI1 and TAL1/SCL in primary human megakaryocytes. Statistical analysis identified subsets of enriched as well as depleted combinatorial binding patterns. In particular simultaneous binding by all 5 factors was highly ...

This SuperSeries is composed of the following subset Series: GSE18240: Saccharomyces cerevisiae cells: control vs positive supercoiling accumulation after 0, 30 and 120 min GSE18241: S. cerevisiae cells: control vs positive supercoiling accumulation in absence of telomere silencing after 0 and 120 m...

This SuperSeries is composed of the following subset Series: GSE29112: The transcriptional program controlled by Runx1 during early hematopoietic development (expression data) GSE29514: The transcriptional program controlled by Runx1 during early hematopoietic development (ChIP-seq data) Refer to in...

Positive DNA helical stress accumulates in vivo by the unbalanced relaxation of positive and negative DNA supercoils in Δtop1, top2ts, pGPD:TopA yeast cells. The resulting overwinding of DNA greatly diminishes overall RNA synthesis. Here we show that whereas most genes reduce their transcript level...
ORGANISM(S): Saccharomyces cerevisiae 
Transcription factors have long been recognised as powerful regulators of mammalian development, yet it is largely unknown how individual key regulators operate within wider regulatory networks. Here we have used a combination of global gene expression and chromatin-immunoprecipitation approaches a...
