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. -

Infantile NCL (INCL), the most severe form of NCL, is caused by mutations in the Ppt1 gene, which encodes the lysosomal enzyme palmitoyl-protein thioesterase 1 (Ppt1). We generated mutations in the Ppt1 ortholog of Drosophila melanogaster in order to characterize phenotypes caused by Ppt1-deficiency in flies. -
Genome-Wide DNA Methylation Analysis of KRAS Mutant Cell Lines Ben Yi Tew1,5, Joel K
www.nature.com/scientificreports OPEN Genome-wide DNA methylation analysis of KRAS mutant cell lines Ben Yi Tew1,5, Joel K. Durand2,5, Kirsten L. Bryant2, Tikvah K. Hayes2, Sen Peng3, Nhan L. Tran4, Gerald C. Gooden1, David N. Buckley1, Channing J. Der2, Albert S. Baldwin2 ✉ & Bodour Salhia1 ✉ Oncogenic RAS mutations are associated with DNA methylation changes that alter gene expression to drive cancer. Recent studies suggest that DNA methylation changes may be stochastic in nature, while other groups propose distinct signaling pathways responsible for aberrant methylation. Better understanding of DNA methylation events associated with oncogenic KRAS expression could enhance therapeutic approaches. Here we analyzed the basal CpG methylation of 11 KRAS-mutant and dependent pancreatic cancer cell lines and observed strikingly similar methylation patterns. KRAS knockdown resulted in unique methylation changes with limited overlap between each cell line. In KRAS-mutant Pa16C pancreatic cancer cells, while KRAS knockdown resulted in over 8,000 diferentially methylated (DM) CpGs, treatment with the ERK1/2-selective inhibitor SCH772984 showed less than 40 DM CpGs, suggesting that ERK is not a broadly active driver of KRAS-associated DNA methylation. KRAS G12V overexpression in an isogenic lung model reveals >50,600 DM CpGs compared to non-transformed controls. In lung and pancreatic cells, gene ontology analyses of DM promoters show an enrichment for genes involved in diferentiation and development. Taken all together, KRAS-mediated DNA methylation are stochastic and independent of canonical downstream efector signaling. These epigenetically altered genes associated with KRAS expression could represent potential therapeutic targets in KRAS-driven cancer. Activating KRAS mutations can be found in nearly 25 percent of all cancers1. -

Read Full License Page 1/27 Abstract Purpose Although tubal factor infertility (TFI) and endometriosis-related infertility all can result in female infertility, the pathogenesis of TFI and endometriosis-related infertility were different. The pathophysiologic mechanisms of TFI and endometriosis-related infertility have not been investigated thoroughly. Thus, the aim of the study is to identify the potential crucial genes, pathways, transcription factors (TFs) and long non-coding RNAs (lncRNAs) associated with TFI and endometriosis-related infertility, and further analyze the molecular mechanism implicated in genes. Methods 3 patients with TFI and 3 patients with endometriosis-related infertility were recruited, and microarray hybridization of the eutopic endometrial tissue during the window of implantation (WOI) was performed to examine the expression of mRNAs and lncRNAs. First, differentially expressed genes (DEGs) and differentially expressed lncRNAs (DELs) were screened out based on P < 0.05 and fold change (FC) ≧ 2. Second, gene ontology, pathway and TFs enrichment analyses and PPI network construction of DEGs were performed. -

All rights reserved 1018-4813/16 www.nature.com/ejhg ARTICLE ASAH1 variant causing a mild SMA phenotype with no myoclonic epilepsy: a clinical, biochemical and molecular study Massimiliano Filosto*,1, Massimo Aureli2, Barbara Castellotti3, Fabrizio Rinaldi1, Domitilla Schiumarini2, Manuela Valsecchi2, Susanna Lualdi4, Raffaella Mazzotti4, Viviana Pensato3, Silvia Rota1, Cinzia Gellera3, Mirella Filocamo4 and Alessandro Padovani1 ASAH1 gene encodes for acid ceramidase that is involved in the degradation of ceramide into sphingosine and free fatty acids within lysosomes. ASAH1 variants cause both the severe and early-onset Farber disease and rare cases of spinal muscular atrophy (SMA) with progressive myoclonic epilepsy (SMA-PME), phenotypically characterized by childhood onset of proximal muscle weakness and atrophy due to spinal motor neuron degeneration followed by occurrence of severe and intractable myoclonic seizures and death in the teenage years. We studied two subjects, a 30-year-old pregnant woman and her 17-year-old sister, affected with a very slowly progressive non-5q SMA since childhood. No history of seizures or myoclonus has been reported and EEG was unremarkable. The molecular study of ASAH1 gene showed the presence of the homozygote nucleotide variation c.124A4G (r.124a4g) that causes the amino acid substitution p.Thr42Ala. Biochemical evaluation of cultured fibroblasts showed both reduction in ceramidase activity and accumulation of ceramide compared with the normal control. This study describes for the first time the association between ASAH1 variants and an adult SMA phenotype with no myoclonic epilepsy nor death in early age, thus expanding the phenotypic spectrum of ASAH1-related SMA. -
Perkinelmer Genomics to Request the Saliva Swab Collection Kit for Patients That Cannot Provide a Blood Sample As Whole Blood Is the Preferred Sample
Progressive Myoclonic Epilepsy Panel Test Code D4004 Test Summary This test analyzes 18 genes that have been associated with Progressive Myoclonic Epilepsy Turn-Around-Time (TAT)* 3 - 5 weeks Acceptable Sample Types DNA, Isolated Dried Blood Spots Saliva Whole Blood (EDTA) Acceptable Billing Types Self (patient) Payment Institutional Billing Commercial Insurance Indications for Testing The early way to tell the difference is an EEG with background slowing. Symptoms like stimulus induced myoclonic jerks, cognitive decline and motor slowing, generalized tonic-clonic seizures, or visual/occipital seizures help narrow the diagnosis. Most importantly, the presence of slowing on the EEG should raise suspicion for PME and, if present, lead to further testing, including genetic and enzyme testing. Test Description This panel analyzes 18 genes that have been associated with Progressive Myoclonic Epilepsy and/or disorders associated with epilepsy. Both sequencing and deletion/duplication (CNV) analysis will be performed on the coding regions of all genes included (unless otherwise marked). All analysis is performed utilizing Next Generation Sequencing (NGS) technology. CNV analysis is designed to detect the majority of deletions and duplications of three exons or greater in size. Smaller CNV events may also be detected and reported, but additional follow-up testing is recommended if a smaller CNV is suspected. All variants are classified according to ACMG guidelines. Condition Description Progressive myoclonic epilepsies (PME) are a group of more than 10 rare types of epilepsy that are “progressive.” People with PME have a decline in motor skills, balance and cognitive function over time. Myoclonus indicates frequent muscle jerks, both spontaneous and often stimulus induced. -
A Study of Neuronal Ceroid Lipofuscinosis Proteins Cln5 and Cln8
A STUDY OF NEURONAL CEROID LIPOFUSCINOSIS PROTEINS CLN5 AND CLN8 By W A BHAGYA NILUKSHI DE SILVA B. S., University of Colombo, Sri Lanka, 2011 A THESIS Submitted in partial fulfillment of the requirements for the degree MASTER OF SCIENCE Department of Biochemistry and Molecular Biophysics College of Arts and Sciences KANSAS STATE UNIVERSITY Manhattan, Kansas 2015 Approved by: Major Professor Dr. Stella Y. Lee ABSTRACT Neuronal ceroid lipofuscinoses (NCLs) are a group of neurodegenerative lysosomal storage disorders which is the most frequent group of inherited neurodegenerative disorders that affect children leading to severe pathological conditions such as progressive loss of motor neuron functions, loss of vision, mental retardation, epilepsy, ataxia and atrophy in cerebral, cerebella cortex and retina and eventually premature death. Among the many genes that cause NCL, mutations in CLN5 leads to different forms of NCL (infantile, late infantile, juvenile and adult) and mutations in CLN8 leads to progressive epilepsy with mental retardation (EPMR) and a variant late infantile form of NCL. The function(s) of both CLN5 and CLN8 proteins remain elusive. CLN5 is a glycosylated soluble protein that resides in the lysosome. We observed that endogenous CLN5 protein exist in two forms and identified a previously unknown C-terminal proteolytic processing event of CLN5. Using a cycloheximide chase experiment we demonstrated that the proteolytic processing of CLN5 is a post-translational modification. Furthermore treatment with chloroquine showed the processing occurs in low pH cellular compartments. After treatment with different protease inhibitors our results suggested the protease involved in the processing of CLN5 could be a cysteine protease. -
