Combining recombinase-mediated cassette exchange strategy with quantitative proteomic and phosphoproteomic analyses to inspect intracellular functions of the tumor supressor galectin-4 in colorectal cancer cells.

ABSTRACT: In order to systematically explore Galectin-4 function in CRC we established a CRC cell line where Gal4 expression can be regulated via doxycycline (dox)-inducible expression of a single copy wildtype LGALS4 transgene generated by recombinase-mediated cassette exchange (RMCE). Using this model and applying in depth proteomic and phosphoproteomic analyses we systematically screened for intracellular changes induced by Gal4 expression by.

Galectin-4 (Gal4) has been suggested to function as a tumor suppressor in colorectal cancer (CRC). In order to systematically explore its function in CRC, we established a CRC cell line where Gal4 expression can be regulated via the doxycycline (dox)-inducible expression of a single copy wildtype <i>LGALS4</i> transgene generated by recombinase-mediated cassette exchange (RMCE). Using this model and applying in-depth proteomic and phosphoproteomic analyses, we systematically screened for intrace ...[more]

The effect of bound RSC/nucleosome complex on chromatin architecture and gene expression at the GAL genes of yeast

Project description:How is chromatin architecture established and what role does it play in activation of transcription? We show that a regulatory locus in yeast (the UASg) bears, in addition to binding sites for the activator Gal4, sites bound by the protein RSC. RSC tightly positions a nucleosome, evidently partially unwound, in a structure that facilitates Gal4 binding to its sites. The complex comprises a barrier that suffices to impose characteristic features of chromatin architecture. Removal of RSC allows ordinary nucleosomes to form more broadly over the UASg, and these nucleosomes compete with (but do not exclude) Gal4 binding to its sites. Taken with our previous work, the results show that both prior to and following induction specific DNA binding proteins are the predominant determinants of chromatin architecture at the GAL1/10 genes. RSC/nucleosome complexes are found scattered throughout the yeast genome. We surmise, also, that Gal4 works in higher eukaryotes despite whatever obstacle broadly positioned nucleosomes present. Chromatin was digested under conditions that yielded primarily mononucleosomes, and RSC-bearing fragments were recovered on IgG-beads. Fragments (of size ca. 50-200 bp) were analyzed by paired-end high throughput DNA sequencing (Illumina). This technique determines the sequences found at both ends of each fragment, thus revealing the sizes and genomic origin of these fragments.

Sequencing of methylated GATC DNA fragments (Targeted DamID) from seven olfactory neuron populations in Drosophila melanogaster

Project description:This project’s aim was to compare the transcriptional profiles of olfactory sensory neurons in Drosophila melanogaster in order to identify novel genes that specify neuron-specific functions/phenotypes or may otherwise be involved in the development of the olfactory system. The isolation of sufficient numbers of intact olfactory sensory neurons (OSN) from the antenna of Drosophila melanogaster has so far limited single-cell transcriptomic approaches being applied to the adult fly antenna. Targeted DamID (TaDa) provides an alternative approach for profiling transcriptional activity in a cell-specific manor that bypasses the need for isolating OSN. Using the Gal4/UAS system, we applied TaDa to seven OSN populations and compared differences in Pol II occupancy for genes across these datasets.

ADAR1-mediated RNA editing promotes B cell lymphomagenesis.

Project description:The project aims to evaluate the contribution of ADAR1 RNA editing to B cell lymphomagenesis, specifically in diffuse large B cell lymphoma (DLBCL). Within our DLBCL cohort, RNA editing targets transcripts within known lymphoma-driving pathways such as apoptosis, p53 and NF-kB signaling, as well as the previously unrecognized RIG-I-like pathway. In the latter context, we show that ADAR1-mediated editing in the MAVS transcript correlates with increased MAVS protein expression levels, associating with increased interferon/NF-kB signaling and increased T cell exhaustion. To confirm this mechanism, we have performed LC-MSMS analysis on a DLBCL cell line (RCK8) in the presence or absence of ADAR1 (Figure S11D ). Additionally, using targeted RNA base editing tools to restore editing within MAVS 3'UTR in ADAR1-deficient cells, we demonstrate that editing is likely to be causal to an increase in downstream signaling in the absence of activation by canonical nucleic acid receptor sensing. To confirm that this signaling increase depends on an increase of MAVS protein upon specific editing, we have performed LC-MSMS analysis on the same samples (Figure 4G).

Immunopurification results of cytoskeletal motor proteins in S. cerevisiae

Project description:The accompanying dataset is the result of a systematic study to identify the RNA cargoes associated with the cytoskeletal motor proteins of Saccharomyces cerevisiae. We immunopurified, via the use of integrated, C-terminal GFP and 9Myc tags, the five actomyosin motors, Myo1, Myo2, Myo3, Myo4, and Myo5; the kinesin-like proteins Kar3, Kip1, Kip2, Kip3, and Smy1; and the dynein, Dyn1, from S. cerevisiae. Cells were either treated with formaldehyde or with the small molecule latrunculin B. We used formaldehyde crosslinking to stabilize associations between motors proteins and interacting RNAs before IP. Yeast cells growing exponentially in rich medium were treated with formaldehyde, lysed and sonicated, then incubated with magnetic beads coupled to monoclonal antibodies against either 9Myc or GFP to isolate the tagged motor proteins along with any associated RNAs. After IP, the formaldehyde crosslinks were reversed and the enriched RNAs and RNAs purified from the corresponding total lysate were amplified and labeled respectively with Cy5 and Cy3, then jointly hybridized to custom-made, S. cerevisiae oligonucleotide microarrays (Hogan et al., PLoS Biology, 2008). Alternatively, the addition of a low concentration of latrunculin B (2 ug/ml) to live cells to partially solubilize the actin cytoskeleton allowed for successful IP of the motor proteins and associated mRNAs without the need for a chemical crosslinker. In both the case of latrunculin B and formaldehyde treatment, we also performed IPs in which the untagged parent yeast strains were processed for IP and microarray analysis in a manner identical to that of the tagged strains (labeled as mock). transcription profiling

Impact of IRP deficiency on the proteome of Ly6G+ cells from the bone marrow in mice

Project description:The overall objective of the project is to evaluate the effects of loss of function of iron regulatory proteins (IRP1, encoded by Aco1)-1 and -2 (IRP2, encoded by Ireb2) during adult life. Mice carrying floxed Aco1 and Ireb2 alleles were crossed to a knockin strain expressing a tamoxifen-inducible CRE recombinase under the control of the Rosa26 promoter. The resulting Aco1flox/flox,Ireb2flox/flox,Rosa26+/CreERT2 mice are designated P1/2-KO; littermates lacking the CreER sequence (Aco1flox/flox,Ireb2flox/flox,Rosa26+/+) serve as reference and are designated P1/2-CTR. Adult mice were injected (i.p.) with tamoxifen on day 1 and day 3 to ablate the IRPs in the whole body, and were sacrificed on day 10 for analysis. Bone marrow cells were collected and LY6G+ cells were magnetically sorted for proteome analysis by LC-MS/MS using an Ultimate 3000 UPLC system connected to an Orbitrap Exploris 480 mass spectrometer.

TEF-seq/NET-seq applied to factors Rpb3, Paf1, Spt6, Spt16, Cet1, Pcf11, Ssu72, Set2

Project description:Here we adapt native elongating transcript sequencing (NET-seq) to develop transcription elongation factor associated nascent elongating transcript sequencing (TEF-seq). In this the RNA polymerase II (Pol2) transcription elongation complex (TEC) is immunoprecipitated via associated transcription elongation factors (TEFs). Sequencing from the 3' end of the Pol2-associated nascent transcript shows the position of the final incorporated nucleotide giving strand-specific, single nucleotide resolution maps of the level of TEF association with Pol2 during transcription.

Nucleosome mapping of Tetrahymena thermophila chromatin in vivo and in vitro

Project description:A conserved hallmark of eukaryotic chromatin architecture is the distinctive array of well-positioned nucleosomes downstream of transcription start sites (TSS). Recent studies indicate that trans-acting factors establish this stereotypical array. Here, we present the first genome-wide in vitro and in vivo nucleosome maps for the ciliate Tetrahymena thermophila. In contrast with previous studies in yeast, we find that the stereotypical nucleosome array is preserved in the in vitro reconstituted map, which is governed only by the DNA sequence preferences of nucleosomes. Remarkably, this average in vitro pattern arises from subsets of nucleosomes, rather than the whole array, being present in individual Tetrahymena genes. Variation in GC content contributes to the positioning of these sequence-directed nucleosomes, and affects codon usage and amino acid composition in genes. We propose that these ‘seed’ nucleosomes may aid the AT-rich Tetrahymena genome – which is intrinsically unfavorable for nucleosome formation – in establishing nucleosome arrays in vivo in concert with trans-acting factors, while minimizing changes to the coding sequences they are embedded within. All data are from the macronuclear genome. Datasets: 1) Log-phase cells, fixed chromatin, light MNase digest; 2) Log-phase cells, native chromatin, heavy MNase digest; 3) Starved cells, fixed chromatin, light MNase digest; 4) Starved cells, native chromatin, heavy MNase digest; 5) in vitro reconstituted chromatin, 50ul reaction, 4:10 histone:DNA ratio, light MNase digest; 6) in vitro reconstituted chromatin, 50ul reaction, 7:10 histone:DNA ratio, light MNase digest; 7) in vitro reconstituted chromatin, 150ul reaction, 4:10 histone:DNA ratio, light MNase digest; 8) in vitro reconstituted chromatin, 150ul reaction, 4:10 histone:DNA ratio, heavy MNase digest; Control dataset: 9): MNase-digested naked DNA
