Human Angiogenin Nuclear Interactions

ABSTRACT: Human Angiogenin (hAng) is a member of the ribonuclease A superfamily and a potent inducer of neovascularization. Herein, protein interactions of hAng in the nucleus and cytoplasm of the human umbilical vein cell line EA.hy926, have been investigated by mass spectroscopy. The first gel-free analysis of hAng immunoprecipitates from the cytoplasmic and nuclear extracts from EA.hy926 cancer human cell line, revealed many statistically significant potential hAng-interacting proteins. The majority of the proteins identified by the mass spectrometry analysis are parts of multiprotein complexes, and some of them are common in nucleus and cytoplasm, including spliceosome, proteasome, and molecular chaperone TRiC/CCT. These complexes are involved in crucial biological pathways, implicating thus the key role of hAng in many vital cellular processes.

Project description:modENCODE_submission_3168 Although C. elegans was the first multicellular organism with a completely sequenced genome, how this genome is arranged within the nucleus is not known. By chromatin immunoprecipitation of the nuclear transmembrane protein LEM-2, we determined the regions of the C. elegans genome associated with the nuclear membrane. We found that large regions of several megabases on the left and right arms of each autosome were associated with the nuclear membrane. The center of each autosome was free of such interactions, suggesting these regions are largely looped out from the nuclear membrane. The X chromosome, unlike the autosomes, was associated with the nuclear membrane only at its left end. At a finer scale, these large membrane-associated domains consist of smaller subdomains of LEM-2 associations. These subdomains are characterized by a high density of repetitive sequences, a low density of genes, and high levels of H3K27 trimethylation. The subdomains were punctuated by gaps containing genes with high transcriptional activity. Finally, we found that a chromosome arm translocated to the center of a chromosome retained its association with the nuclear membrane, although there was a decrease of association up to 400 kb from the fusion point. This indicates that local chromatin properties are the main determinant of interaction with the nuclear membrane, but the degree of association can be modulated by position along the chromosome. Our data provide the foundation for a model of the spatial arrangement of C.elegans chromosomes within the nucleus. Supplemental materials are available online at http://www.genome.org .

Project description:Determining how facultative anaerobic organisms sense and direct cellular responses to electron acceptor availability has been a subject of intense study. However, even in the model organism Escherichia coli, established mechanisms only explain a small fraction of the hundreds of genes that are regulated during shifts in electron acceptor availability. Here we propose a qualitative model that accounts for the full breadth of regulated genes by detailing how two global transcription factors (TFs), ArcA and Fnr of E. coli, sense key metabolic redox ratios and act on a genome-wide basis to regulate anabolic, catabolic, and energy generation pathways. We first fill gaps in our knowledge of this transcriptional regulatory network by carrying out ChIP-chip and gene expression experiments to identify 463 regulatory events. We then interfaced this reconstructed regulatory network with a highly curated genome-scale metabolic model to show that ArcA and Fnr regulate > 80% of total metabolic flux and 96% of differential gene expression across fermentative and nitrate respiratory conditions. Finally, based on the data we propose a feedforward with feedback trim regulatory scheme by showing extensive repression of catabolic genes by ArcA and extensive activation of chemiosmotic genes by Fnr. We further corroborated this regulatory scheme by showing a 0.71 r2 (p < 1e-6) correlation between changes in metabolic flux and changes in regulatory activity across fermentative and nitrate respiratory conditions. We also are able to relate the proposed model to a wealth of previously generated data by contextualizing the existing transcriptional regulatory network. We integrated transcription factor binding regions and mRNA transcript abundance to elucidate the ArcA and Fnr regulons experimentally. To measure transcription factor binding at a genome scale, we employed a ChIP-chip method to derivative strains of E. coli K-12 MG1655 harboring ArcA-8myc or Fnr-8myc under various conditions. The E. coli strains harboring Fnr-8myc and ArcA-8myc were generated as described previously [PMID 16454042]. A 12 chip study with two different strains under two different culture conditions.
