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. -

Patterns of DNA methylation on the human X chromosome and use in analyzing X-chromosome inactivation by Allison Marie Cotton B.Sc., The University of Guelph, 2005 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in The Faculty of Graduate Studies (Medical Genetics) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) January 2012 © Allison Marie Cotton, 2012 Abstract The process of X-chromosome inactivation achieves dosage compensation between mammalian males and females. In females one X chromosome is transcriptionally silenced through a variety of epigenetic modifications including DNA methylation. Most X-linked genes are subject to X-chromosome inactivation and only expressed from the active X chromosome. On the inactive X chromosome, the CpG island promoters of genes subject to X-chromosome inactivation are methylated in their promoter regions, while genes which escape from X- chromosome inactivation have unmethylated CpG island promoters on both the active and inactive X chromosomes. The first objective of this thesis was to determine if the DNA methylation of CpG island promoters could be used to accurately predict X chromosome inactivation status. The second objective was to use DNA methylation to predict X-chromosome inactivation status in a variety of tissues. A comparison of blood, muscle, kidney and neural tissues revealed tissue-specific X-chromosome inactivation, in which 12% of genes escaped from X-chromosome inactivation in some, but not all, tissues. X-linked DNA methylation analysis of placental tissues predicted four times higher escape from X-chromosome inactivation than in any other tissue. Despite the hypomethylation of repetitive elements on both the X chromosome and the autosomes, no changes were detected in the frequency or intensity of placental Cot-1 holes. -

Co-Expression Network of Neural-Differentiation Genes Shows
Maschietto et al. BMC Medical Genomics (2015) 8:23 DOI 10.1186/s12920-015-0098-9 RESEARCH ARTICLE Open Access Co-expression network of neural-differentiation genes shows specific pattern in schizophrenia Mariana Maschietto1,2†, Ana C Tahira1,2†, Renato Puga3, Leandro Lima4, Daniel Mariani4, Bruna da Silveira Paulsen5, Paulo Belmonte-de-Abreu6, Henrique Vieira4, Ana CV Krepischi7, Dirce M Carraro8, Joana A Palha9,10, Stevens Rehen5,11 and Helena Brentani1,2,12,13* Abstract Background: Schizophrenia is a neurodevelopmental disorder with genetic and environmental factors contributing to its pathogenesis, although the mechanism is unknown due to the difficulties in accessing diseased tissue during human neurodevelopment. The aim of this study was to find neuronal differentiation genes disrupted in schizophrenia and to evaluate those genes in post-mortem brain tissues from schizophrenia cases and controls. Methods: We analyzed differentially expressed genes (DEG), copy number variation (CNV) and differential methylation in human induced pluripotent stem cells (hiPSC) derived from fibroblasts from one control and one schizophrenia patient and further differentiated into neuron (NPC). Expression of the DEG were analyzed with microarrays of post-mortem brain tissue (frontal cortex) cohort of 29 schizophrenia cases and 30 controls. A Weighted Gene Co-expression Network Analysis (WGCNA) using the DEG was used to detect clusters of co-expressed genes that werenon-conserved between adult cases and controls brain samples. Results: We identified methylation alterations potentially involved with neuronal differentiation in schizophrenia, which displayed an over-representation of genes related to chromatin remodeling complex (adjP = 0.04). We found 228 DEG associated with neuronal differentiation. -

Armcx3 and Armc10/SVH are characterized by high expression in the central nervous system and they play an important role in the regulation of mitochondrial distribution and transport in neurons. In addition, Armcx/Arm10 genes have several Armadillo repeats in their sequence. In this study we address the potential role of this gene family in neural development by using the chick neural tube as a model. We Edited by: show that Armc10/SVH is expressed in the chicken spinal cord, and knocking-down Christian Hansel, Armc10/SVH by sh-RNAi electroporation in spinal cord reduces proliferation of neural University of Chicago, USA precursor cells (NPCs).

Low Professor Suzanne Moenter Professor Audrey Seasholtz Before you leave these portals To meet less fortunate mortals There's just one final message I would give to you: You all have learned reliance On the sacred teachings of science So I hope, through life, you never will decline In spite of philistine defiance To do what all good scientists do: Experiment! -- Cole Porter There is no cure for curiosity. -- unknown © Margaret Brewster Allison 2015 ACKNOWLEDGEMENTS If it takes a village to raise a child, it takes a research university to raise a graduate student. There are many people who have supported me over the past six years at Michigan, and it is hard to imagine pursuing my PhD without them. First and foremost among all the people I need to thank is my mentor, Martin. Nothing I might say here would ever suffice to cover the depth and breadth of my gratitude to him. Without his patience, his insight, and his at times insufferably positive outlook, I don’t know where I would be today. Martin supported my intellectual curiosity, honed my scientific inquiry, and allowed me to do some really fun research in his lab. It was a privilege and a pleasure to work for him and with him. -
The Pdx1 Bound Swi/Snf Chromatin Remodeling Complex Regulates Pancreatic Progenitor Cell Proliferation and Mature Islet Β Cell

Here we demonstrate that mouse pancreas size and islet β cell function are controlled by the ATP-dependent Swi/Snf chromatin remodeling coregulatory complex that physically associates with Pdx1, a diabetes- linked transcription factor essential to pancreatic morphogenesis and adult islet-cell function and maintenance. Early embryonic deletion of just the Swi/Snf Brg1 ATPase subunit reduced multipotent pancreatic progenitor cell proliferation and resulted in pancreas hypoplasia. In contrast, removal of both Swi/Snf ATPase subunits, Brg1 and Brm, was necessary to compromise adult islet β cell activity, which included whole animal glucose intolerance, hyperglycemia and impaired insulin secretion. Notably, lineage-tracing analysis revealed Swi/Snf-deficient β cells lost the ability to produce the mRNAs for insulin and other key metabolic genes without effecting the expression of many essential islet-enriched transcription factors. -
