Cooperativity of Imprinted Genes Inactivated by Acquired Chromosome 20Q Deletions
Cooperativity of imprinted genes inactivated by acquired chromosome 20q deletions Athar Aziz, … , Anne C. Ferguson-Smith, Anthony R. Green J Clin Invest. 2013;123(5):2169-2182. https://doi.org/10.1172/JCI66113. Research Article Oncology Large regions of recurrent genomic loss are common in cancers; however, with a few well-characterized exceptions, how they contribute to tumor pathogenesis remains largely obscure. Here we identified primate-restricted imprinting of a gene cluster on chromosome 20 in the region commonly deleted in chronic myeloid malignancies. We showed that a single heterozygous 20q deletion consistently resulted in the complete loss of expression of the imprinted genes L3MBTL1 and SGK2, indicative of a pathogenetic role for loss of the active paternally inherited locus. Concomitant loss of both L3MBTL1 and SGK2 dysregulated erythropoiesis and megakaryopoiesis, 2 lineages commonly affected in chronic myeloid malignancies, with distinct consequences in each lineage. We demonstrated that L3MBTL1 and SGK2 collaborated in the transcriptional regulation of MYC by influencing different aspects of chromatin structure. L3MBTL1 is known to regulate nucleosomal compaction, and we here showed that SGK2 inactivated BRG1, a key ATP-dependent helicase within the SWI/SNF complex that regulates nucleosomal positioning. These results demonstrate a link between an imprinted gene cluster and malignancy, reveal a new pathogenetic mechanism associated with acquired regions of genomic loss, and underline the complex molecular and cellular consequences of “simple” cancer-associated chromosome deletions.

Molecular and Cellular Mechanisms of the Angiogenic Effect of Poly(Methacrylic Acid-Co-Methyl Methacrylate) Beads
Molecular and Cellular Mechanisms of the Angiogenic Effect of Poly(methacrylic acid-co-methyl methacrylate) Beads by Lindsay Elizabeth Fitzpatrick A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Institute of Biomaterials and Biomedical Engineering University of Toronto © Copyright by Lindsay Elizabeth Fitzpatrick 2012 Molecular and Cellular Mechanisms of the Angiogenic Effect of Poly(methacrylic acid-co-methyl methacrylate) Beads Lindsay Elizabeth Fitzpatrick Doctorate of Philosophy Institute of Biomaterials and Biomedical Engineering University of Toronto 2012 Abstract Poly(methacrylic acid -co- methyl methacrylate) beads were previously shown to have a therapeutic effect on wound closure through the promotion of angiogenesis. However, it was unclear how this polymer elicited its beneficial properties. The goal of this thesis was to characterize the host response to MAA beads by identifying molecules of interest involved in MAA-mediated angiogenesis (in comparison to poly(methyl methacrylate) beads, PMMA). Using a model of diabetic wound healing and a macrophage-like cell line (dTHP-1), eight molecules of interest were identified in the host response to MAA beads. Gene and/or protein expression analysis showed that MAA beads increased the expression of Shh, IL-1β, IL-6, TNF- α and Spry2, but decreased the expression of CXCL10 and CXCL12, compared to PMMA and no beads. MAA beads also appeared to modulate the expression of OPN. In vivo, the global gene expression of OPN was increased in wounds treated with MAA beads, compared to PMMA and no beads. In contrast, dTHP-1 decreased OPN gene expression compared to PMMA and no beads, but expressed the same amount of secreted OPN, suggesting that the cells decreased the expression of the intracellular isoform of OPN. -
Discovering Protein-Binding RNA Motifs with a Generative Model of RNA Sequences T

Motivated by the big experimental data, several computational Binding motif methods have been developed either to predict binding sites in a sequence or to determine if an interaction exists Generator between protein and nucleic acid sequences. However, most of the methods cannot be used to discover new Long short-term memory network nucleic acid sequences that bind to a target protein because they are classifiers rather than generators. In this paper we propose a generative model for constructing protein-binding RNA sequences and motifs using a long short-term memory (LSTM) neural network. Testing the model for several target proteins showed that RNA sequences generated by the model have high binding affinity and specificity for their target proteins and that the protein-binding motifs derived from the generated RNA sequences are comparable to the motifs from experi- mentally validated protein-binding RNA sequences. The results are promising and we believe this approach will help design more efficient in vitro or in vivo experiments by suggesting potential RNA aptamers for a target protein. 1.

Chronic Exposure of Humans to High Level Natural Background Radiation Leads to Robust Expression of Protective Stress Response Proteins S
www.nature.com/scientificreports OPEN Chronic exposure of humans to high level natural background radiation leads to robust expression of protective stress response proteins S. Nishad1,2, Pankaj Kumar Chauhan3, R. Sowdhamini3 & Anu Ghosh1,2* Understanding exposures to low doses of ionizing radiation are relevant since most environmental, diagnostic radiology and occupational exposures lie in this region. However, the molecular mechanisms that drive cellular responses at these doses, and the subsequent health outcomes, remain unclear. A local monazite-rich high level natural radiation area (HLNRA) in the state of Kerala on the south-west coast of Indian subcontinent show radiation doses extending from ≤ 1 to ≥ 45 mGy/y and thus, serve as a model resource to understand low dose mechanisms directly on healthy humans. We performed quantitative discovery proteomics based on multiplexed isobaric tags (iTRAQ) coupled with LC–MS/MS on human peripheral blood mononuclear cells from HLNRA individuals. Several proteins involved in diverse biological processes such as DNA repair, RNA processing, chromatin modifcations and cytoskeletal organization showed distinct expression in HLNRA individuals, suggestive of both recovery and adaptation to low dose radiation. In protein–protein interaction (PPI) networks, YWHAZ (14-3-3ζ) emerged as the top-most hub protein that may direct phosphorylation driven pro- survival cellular processes against radiation stress. PPI networks also identifed an integral role for the cytoskeletal protein ACTB, signaling protein PRKACA; and the molecular chaperone HSPA8. The data will allow better integration of radiation biology and epidemiology for risk assessment [Data are available via ProteomeXchange with identifer PXD022380]. Te basic principles of low linear energy transfer (LET) ionizing radiation (IR) induced efects on mammalian systems have been broadly explored and there exists comprehensive knowledge on the health efects of high doses of IR delivered at high dose rates. -

Visualization of Human Karyopherin Beta-1/Importin Beta-1 Interactions
www.nature.com/scientificreports OPEN Visualization of human karyopherin beta-1/importin beta-1 interactions with protein partners in mitotic Received: 28 April 2017 Accepted: 29 December 2017 cells by co-immunoprecipitation Published: xx xx xxxx and proximity ligation assays Laura Di Francesco1,4, Annalisa Verrico2, Italia Anna Asteriti2, Paola Rovella2, Pietro Cirigliano3, Giulia Guarguaglini2, Maria Eugenia Schinin1 & Patrizia Lavia 2 Karyopherin beta-1/Importin beta-1 is a conserved nuclear transport receptor, acting in protein nuclear import in interphase and as a global regulator of mitosis. These pleiotropic functions refect its ability to interact with, and regulate, diferent pathways during the cell cycle, operating as a major efector of the GTPase RAN. Importin beta-1 is overexpressed in cancers characterized by high genetic instability, an observation that highlights the importance of identifying its partners in mitosis. Here we present the frst comprehensive profle of importin beta-1 interactors from human mitotic cells. By combining co-immunoprecipitation and proteome-wide mass spectrometry analysis of synchronized cell extracts, we identifed expected (e.g., RAN and SUMO pathway factors) and novel mitotic interactors of importin beta-1, many with RNA-binding ability, that had not been previously associated with importin beta-1. These data complement interactomic studies of interphase transport pathways. We further developed automated proximity ligation assay (PLA) protocols to validate selected interactors. We succeeded in obtaining spatial and temporal resolution of genuine importin beta-1 interactions, which were visualized and localized in situ in intact mitotic cells. Further developments of PLA protocols will be helpful to dissect importin beta-1-orchestrated pathways during mitosis. -
