Project description:We have employed short-capped RNA sequencing (sc-RNA-seq) in order to identify genes whose expression is regulated by promoter proximal pausing of RNA Polymerase II (RNAPI) in response to stress stimulation. We used serum-deprived mouse Swiss 3T3 fibroblasts, either untreated (control) or treated with anisomycin to induce the p38/MAP kinase pathway.

We used serum-deprived mouse Swiss 3T3 fibroblasts, either untreated (control) or treated with anisomycin to induce the p38/MAP kinase pathway. Serum starved (72 h 0.2% FCS) mouse 3T3 cells were treated with anisomycin (188.5 nM) for 1 h (in duplicates). Untreated, serum-starved cells were used as a control. We isolated nuclear RNA, performed size fractionation followed by isolation of short-capped RNAs (scRNA). scRNAs were subsequently converted into DNA library and sequenced.

Project description:Many mammalian genes are occupied by paused RNA polymerase II (pol II) at promoter-proximal regions on both sides of transcription start sites (TSSs). However, the consequences of pol II pausing on gene expression and cell biology are not fully understood. Here we report that genetic ablation of the b subunit of mouse negative elongation factor (Nelf-b), a key pol II-pausing factor, results in slower progression at multiple cell cycle stages and increased apoptosis. Consistently, a whole-genome analysis indicates that growth and cell death-related genes are highly enriched among the direct target genes of Nelf-b. In particular, Nelf-b deletion increases pol II density in the promoter-distal region of stress response genes and their overall expression levels in the absence of any external stress signals. In addition, our work also reveals a previously unappreciated role of Nelf-b role in curbing TSS-upstream transcription of many mammalian genes. We suggest that Nelf-mediated pol II pausing balances the cellular needs for growth/survival and stress response by preventing excessive basal transcription of stress-induced genes.

Immortalized mouse embryonic fibroblasts derived from a Nelf-b flox/- embryo were infected with control or Cre-epxressing retrovirus. Gene expression profile of control and knockout MEF at 7 days after virus infection were compared by using Illumina's mouse whole-genome gene expression BeadChIPs. There are two replicates for both control and knockout MEF samples.
