(Submitter supplied) The transcription factor c-MYC intron binding protein 1 (MIBP1) binds to various genomic regulatory regions, including intron 1 of c-MYC. This factor is highly expressed in post-mitotic neurons in the fetal brain and may be involved in various biological steps, such as neurological and immunological processes. In this study, we globally characterized the transcriptional targets of MIBP1 and proteins that interact with MIBP1. more...

(Submitter supplied) O-GlcNAc transferase (OGT) is overexpressed in aggressive prostate cancer. Here, we employed ChIP-seq to map chromatin-bound O-GlcNAc loci in prostate cancer cells and discovered that these overlap with sites of active transcription and MYC binding. Using RNA-seq, we show that inhibition of OGT promotes MYC-dependent transcriptional repression of mRNAs involved in G1-S transition. O-GlcNAc ChIP-seq regions are highly enriched to transcription start sites and identify the ‘GFY’-motif. more...

(Submitter supplied) Drosophila development is a complex and dynamic process regulated, in part, by members of the Polycomb (Pc), Trithorax (Trx) and Compass chromatin modifier complexes. O-GlcNAc Transferase (OGT/SXC) is essential for Pc repression suggesting that the O-GlcNAcylation of proteins plays a key role in regulating development. OGT transfers N-acetyl-D-glucosamine (GlcNAc) onto hydroxyl groups of serine or threonine residues of key transcriptional regulators using the nutrient-derived UDP-GlcNAc as a substrate, which is dynamically removed by O-GlcNAcase (OGA). more...

(Submitter supplied) Nutrient-responsive oogenesis in Drosophila is a complex and dynamic process regulated, in part, by members of the Pc and Trx complexes. The recent finding that O-GlcNAc Transferase (ogt/sxc) is essential for Pc repression raises the question of whether this nutrient-sensing pathway plays a role in regulating oogenesis. OGT transfers O-GlcNAc to key transcriptional regulators in response to graded levels of the nutrient-derived precursor UDP-GlcNAc; O-GlcNAcase (OGA) catalyzes the removal of O-GlcNAc. more...

(Submitter supplied) TNF time course series of HelA tet off cells cultured in presence or absence of Dox TNF is a pro-inflammatory cytokine that controls expression of inflammatory genetic networks. Although the Nuclear Factor-kB (NF-kB) pathway is crucial for mediating cellular TNF responses, the complete spectrum of NF-kB dependent genes is unknown. In this study, we used a tetracycline-regulated cell line expressing an NF-kB inhibitor to systematically identify NF-kB dependent genes. more...

(Submitter supplied) Malignant cells of Hodgkin's lymphoma (HL) cells are characterized by constitutive activation of the canonical as well as the non-canonical NF-κB signaling cascades. Knockdown of a subunit combination corresponding to the non-canonical NF-κB dimer (p52/RelB) in the HL cell line L-1236 caused up-regulation of a set of genes that are associated with hematopoietic and lymphoid organ development. As p52 can form homodimeric complexes, which can repress transcription either alone or in association with transcriptional repressors such as HDAC1, we knocked down p52 alone to analyze its role in gene repression in HL cells. more...

(Submitter supplied) Malignant Hodgkin's lymphoma (HL) cells are characterized by constitutive activation of the canonical as well as the non-canonical NF-κB signaling cascades. We depleted subunit combinations corresponding to either canonical (p50/RelA) or non-canonical (p52/RelB) dimers in the HL cell line L-1236 and performed Affymetrix microarray analysis. Knockdown of p52/RelB affected the expression of a significantly higher number of genes than the knockdown of p50/RelA. more...

(Submitter supplied) The malignant cells of Hodgkin's lymphoma are characterized by a constitutive activation of the canonical as well as the non-canonical NF-κB signaling cascades. We carried out genome-wide localization and expression profiling experiments in the Hodgkin lymphoma cell line L1236 for the canonical and non-canonical NF-κB pathway components p65, p50 and p52, RelB, respectively. We found that the single NF-κB subunits bind to overlapping, but distinct cistromes by using consensus motifs of high similarity.

(Submitter supplied) Tumorigenesis is characterised by changes in transcriptional regulation and the androgen receptor (AR) has been identified as a key driver in prostate cancer. In this study, we show that the hexosamine biosynthetic pathway (HBP) genes are overexpressed in clinical prostate cancer and androgen-regulated in cell-lines. HBP senses metabolic status of the cell and produces an essential substrate for O-GlcNAc transferase (OGT), which regulates target proteins via glycosylation. more...

(Submitter supplied) Methylated mammalian promoters are transcriptionally silenced even in the presence of all the factors required for their expression. Repression requires the assembly of a methylation-dependent silencing complex that contains the TRIM28 (also known as KAP1 and TIF1β) protein. An internally controlled interaction screen identified O-linked β-N-acetylglucosamine transferase (O-GlcNAc transferase or OGT) as a protein that was complexed with TRIM28 in wild type em-bryonic stem cells but not in Dnmt1-/- cells that had severely demethylated genomes. more...
