Applicability of Multidimensional Fractionation to Affinity Purification Mass Spectrometry Samples and Protein Phosphatase 4 Substrate Identification
Applicability of Multidimensional Fractionation to Affinity Purification Mass Spectrometry Samples and Protein Phosphatase 4 Substrate Identification by Wade Hampton Dunham A thesis submitted in conformity with the requirements for the degree of Master of Science Department of Molecular Genetics University of Toronto © Copyright by Wade Dunham 2012 ii Applicability of Multidimensional Fractionation to Affinity Purification Mass Spectrometry Samples and Protein Phosphatase 4 Substrate Identification Wade Dunham Master of Science Department of Molecular Genetics University of Toronto 2012 Abstract Affinity-purification coupled to mass spectrometry (AP-MS) is gaining widespread use for the identification of protein-protein interactions. It is unclear however, whether typical AP sample complexity is limiting for the identification of all protein components using standard one-dimensional LC-MS/MS. Multidimensional sample separation is a useful for reducing sample complexity prior to MS analysis, and increases peptide and protein coverage of complex samples, yet the applicability of this approach to AP-MS samples remains unknown. Here I present work to show that multidimensional separation of AP-MS samples is not a cost-effective method for identifying increased peptide or protein coverage in these sample types. As such this approach was not adapted for the identification of putative Phosphoprotein Phosphatase 4 (PP4c) substrates. Instead, affinity purification coupled to one- dimensional LC-MS/MS was used to identify putative PP4c substrates, and semi- quantitative methods applied to identify possible PP4c targeted phosphosites in PP2A subfamily phosphatase inhibited (okadaic acid treated) cells. iii Acknowledgments I would like to acknowledge and thank everyone in the Gingras lab, in particular my supervisor Anne-Claude, for allowing me to take on complex projects and to be an integral part in the pursuit of high impact publications. -
In Vitro Differentiation of Bone Marrow Mesenchymal Stem Cells Into Endometrial Epithelial Cells in Mouse: a Proteomic Analysis

China Received March 24, 2014; Accepted June 23, 2014; Epub June 15, 2014; Published July 1, 2014 Abstract: Objective: Mouse bone marrow mesenchymal stem cells (BMSCs) have been demonstrated to differenti- ate into female endometrial epithelial cells (EECs) in vivo. Our previous studies demonstrated that BMSCs can differentiate in the direction of EECs when co-cultured with endometrial stromal cells in vitro. Here, we obtain and analyse differential proteins and their relevant pathways in the process of BMSCs differentiating into EECs by iso- baric tags for relative and absolute quantitation (iTRAQ) proteomic analysis. Methods: A 0.4-µm pore size indirect co- culture system was established with female mice endometrial stromal cells (EStCs) restricted in the upper Transwell chamber and BMSCs in the lower well plate. After indirect co-culture for several days, the BMSCs were revealed to progressively differentiate towards EECs in vitro. Then, four groups were divided according to different co-culture days with single culture groups of BMSCs as controls. -

Recently, the next-generation sequencing (NGS) technologies allowed us to detect ASE genes at a transcriptome-wide level. It is essential for the understanding of animal development, cellular programming, and the effect on their complexity because ASE shows developmental, tissue, or species-specific patterns. However, these aspects of ASE still have not been annotated well in farm animals and most studies were conducted mainly at the fetal stages. Hence, the current study focuses on detecting ASE genes in 17 tissues in adult cattle. -

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated. -

Nesprins: from the Nuclear Envelope and Beyond
expert reviews http://www.expertreviews.org/ in molecular medicine Nesprins: from the nuclear envelope and beyond Dipen Rajgor and Catherine M. Shanahan* Nuclear envelope spectrin-repeat proteins (Nesprins), are a novel family of nuclear and cytoskeletal proteins with rapidly expanding roles as intracellular scaffolds and linkers. Originally described as proteins that localise to the nuclear envelope (NE) and establish nuclear-cytoskeletal connections, nesprins have now been found to comprise a diverse spectrum of tissue specific isoforms that localise to multiple sub-cellular compartments. Here, we describe how nesprins are necessary in maintaining cellular architecture by acting as essential scaffolds and linkers at both the NE and other sub-cellular domains. More importantly, we speculate how nesprin mutations may disrupt tissue specific nesprin scaffolds and explain the tissue specific nature of many nesprin-associated diseases, including laminopathies. The eukaryotic cytoplasm contains three major composed of three α-helical bundles with a left- types of cytoskeletal filaments: Filamentous- handed twist, and its primary function is to actin (F-actin), microtubules (MTs) and provide docking sites for proteins and other intermediate filaments (IFs). These components higher order complexes (Refs 3, 4). Although are organised in a manner that provides the cell most SR proteins contain CHDs, some possess with an internal framework fundamental for motifs which can interact with other cytoskeletal many processes, such as controlling cellular components, allowing linkage of SR-associated shape, polarity, adhesion and migration, complexes to filamentous structures other than cytokinesis, inter- and intracellular F-actin. In addition, these motifs allow cross- Nesprins: from the nuclear envelope and beyond communication and trafficking of organelles, linking between different filaments and dynamic vesicles, proteins and RNA (Refs 1, 2). -
Reporterseq Reveals Genome-Wide Dynamic Modulators of the Heat
RESEARCH ARTICLE ReporterSeq reveals genome-wide dynamic modulators of the heat shock response across diverse stressors Brian D Alford1†, Eduardo Tassoni-Tsuchida1,2†, Danish Khan1, Jeremy J Work1, Gregory Valiant3, Onn Brandman1* 1Department of Biochemistry, Stanford University, Stanford, United States; 2Department of Biology, Stanford University, Stanford, United States; 3Department of Computer Science, Stanford University, Stanford, United States Abstract Understanding cellular stress response pathways is challenging because of the complexity of regulatory mechanisms and response dynamics, which can vary with both time and the type of stress. We developed a reverse genetic method called ReporterSeq to comprehensively identify genes regulating a stress-induced transcription factor under multiple conditions in a time- resolved manner. ReporterSeq links RNA-encoded barcode levels to pathway-specific output under genetic perturbations, allowing pooled pathway activity measurements via DNA sequencing alone and without cell enrichment or single-cell isolation. We used ReporterSeq to identify regulators of the heat shock response (HSR), a conserved, poorly understood transcriptional program that protects cells from proteotoxicity and is misregulated in disease. Genome-wide HSR regulation in budding yeast was assessed across 15 stress conditions, uncovering novel stress-specific, time- specific, and constitutive regulators. ReporterSeq can assess the genetic regulators of any transcriptional pathway with the scale of pooled genetic screens and the precision of pathway- specific readouts. *For correspondence: [email protected] †These authors contributed equally to this work Introduction Competing interests: The The heat shock response (HSR) is a conserved stress response that shields cells from cytoplasmic authors declare that no proteotoxicity by increasing the expression of protective proteins (Lindquist, 1986; Mori- competing interests exist. -
