Gene knockdown suggests a new paradigm for transcription factor TFIIB functionality

Project description:Experimental and bioinformatic studies of transcription initiation by RNA polymerase II (RNAP2) have revealed a mechanism of RNAP2 transcription initiation less uniform across gene promoters than initially thought. However, the general transcription factor TFIIB is presumed to be universally required for RNAP2 transcription initiation. Based on bioinformatic analysis of data, TFIIB knockdown in primary and transformed cell lines, and in vitro transcription experiments, we report that TFIIB is dispensable for transcription of most human promoters, but is essential for HSV-1 gene transcription and replication. We report a novel cell cycle TFIIB regulation and involvement of the acetylated TFIIB variant in chromosomal condensation. Taken together, these results establish a new paradigm for TFIIB functionality as a determinant of the human transcriptome, which when downregulated has potent anti-viral effects.

Comparative ChIP-chip analysis of general transcription factor TFIIB and negative cofactor NC2 in human B cells

Project description:A comparative ChIP-chip analysis of TFIIB and NC2 in human B cells reveals that basal core promoter architectures control the equilibrium between NC2 and preinitiation complexes. We conducted a comparative ChIP-chip and gene expression analysis of TFIIB in human B cells and analyze associated core promoter architectures. TFIIB occupancy relates well to gene expression, with the vast majority of promoters being GC-rich and lacking defined core promoter elements. TATA consensus and TATA-like motifs but not the previously in vitro defined TFIIB recognition elements (BREs) are enriched in approximately 5% of the genes. Further insight was obtained by performing a parallel ChIP-chip analysis of the TFIIB antagonist NC2. The latter identifies a highly related target gene set. Nonetheless, subpopulations show strong variations in TFIIB/NC2 ratios, with high NC2/TFIIB ratios correlating to promoters that show dispersed transcription start site patterns and lacking defined core elements. Conversely, high TFIIB/NC2 ratios select for conserved core promoter elements that include TATA and INR (initiator), the upstream TFIIB recognition element (BREu) and the downstream promoter element (DPE). Two biological samples from LCL 721 lymphoblastoid human B cells were subjected to ChIP-chip analysis of TFIIB and NC2 using a Nimblegen human promoter array (based on the HG17 genome build) covering 1.5 kb DNA around transcription start sites.

Genome wide TFIIB binding during postnatal and pressure-induced cardiac hypertrophy

Project description:Purpose: To identify the differential TFIIB bindingl patterns during postnatal cardiac growth, pressure-induced cardiac hypertrophy and adult mouse hearts Methods: Hearts were extracted from 1-2day old C57 mice, from mice subjecetd to Transaortic coarctation or adult mice. The hearts were sent to Active Motif for TFIIB- ChIP-Seq. Results: In accordance with previosly published data (Sayed D, et. al. JBC, 2013 Jan 25;288(4):2546-58) with genome wide polII and H3K9ac status during cardiac hypertrophy (GSE50637), Denovo TFIIB recruitment was restricted to speclaized genes with cardiac hypertrophy. Hearts were extracted from 1-2day old C57 mice, from mice subjecetd to Transaortic coarctation or adult mice. The hearts were sent to Active Motif for TFIIB- ChIP-Seq.

Transcriptome of TNF-a-treated and untreated HeLa cells before and after TFIIB knockdown

Project description:The goal of this study was to compare transcriptome of HeLa cells with or without TFIIB knockdown for gene expression changes in steady state or after TNF-a treatment. Although a broad effect on gene expression would be anticipated, TFIIB depletion led only to an altered expression of a limited number of genes.
