Sphingolipidoses are a group of inherited genetic diseases characterized by the unmetabolized sphingolipids and the consequent reduction of ceramide pool in lysosomes. Sphingolipidoses include several disorders as Sandhoff disease, Fabry disease, Gaucher disease, metachromatic leukodystrophy, Krabbe disease, Niemann Pick disease, Farber disease, and GM2 gangliosidosis. In sphingolipidosis, lysosomal lipid storage occurs in both the central nervous system and visceral tissues, and central nervous system pathology is a common hallmark for all of them. Parkinson’s disease, the most common neurodegenerative movement disorder, is characterized by the accumulation and aggregation of misfolded α-synuclein that seem associated to some lysosomal disorders, in particular Gaucher disease. This review provides evidence into the role of ceramide metabolism in the pathophysiology of lysosomes, highlighting the more recent findings on its involvement in Parkinson’s disease.

Identification of Potential Autoantigens in Anti-CCP-Positive and Anti-CCP-Negative Rheumatoid Arthritis Using Citrulline-Specific Protein Arrays
www.nature.com/scientificreports OPEN Identifcation of potential autoantigens in anti‑CCP‑positive and anti‑CCP‑negative rheumatoid arthritis using citrulline‑specifc protein arrays Thomas B. G. Poulsen 1,2, Dres Damgaard 3, Malene M. Jørgensen 4,5, Ladislav Senolt6, Jonathan M. Blackburn 7, Claus H. Nielsen 3,8 & Allan Stensballe 1,8* The presence or absence of autoantibodies against citrullinated proteins (ACPAs) distinguishes two main groups of rheumatoid arthritis (RA) patients with diferent etiologies, prognoses, disease severities, and, presumably, disease pathogenesis. The heterogeneous responses of RA patients to various biologics, even among ACPA‑positive patients, emphasize the need for further stratifcation of the patients. We used high‑density protein array technology for fngerprinting of ACPA reactivity. Identifcation of the proteome recognized by ACPAs may be a step to stratify RA patients according to immune reactivity. Pooled plasma samples from 10 anti‑CCP‑negative and 15 anti‑CCP‑positive RA patients were assessed for ACPA content using a modifed protein microarray containing 1631 diferent natively folded proteins citrullinated in situ by protein arginine deiminases (PADs) 2 and PAD4. IgG antibodies from anti‑CCP‑positive RA plasma showed high‑intensity binding to 87 proteins citrullinated by PAD2 and 99 proteins citrullinated by PAD4 without binding signifcantly to the corresponding native proteins. Curiously, the binding of IgG antibodies in anti‑CCP‑negative plasma was also enhanced by PAD2‑ and PAD4‑mediated citrullination of 29 and 26 proteins, respectively. For only four proteins, signifcantly more ACPA binding occurred after citrullination with PAD2 compared to citrullination with PAD4, while the opposite was true for one protein. -
The Protein Arginine Deiminases
The Protein Arginine Deiminases: Inhibitors and Characteristics By Elizabeth Joanne Curiel Tejeda A thesis submitted in conformity with the requirements for the degree of Master of Science Pharmaceutical Sciences University of Toronto © Copyright by Elizabeth Joanne Curiel Tejeda (2015) Abstract The Protein Arginine Deiminases: Inhibitors and Characteristics MSc Pharmaceutical Sciences Convocation year of 2015 Elizabeth Joanne Curiel Tejeda Department of Pharmaceutical Sciences University of Toronto Protein arginine deiminases (PADs) are Ca2+ dependent enzymes involved in the post- translational modification of proteins through citrullination. Overexpression of PAD2 and PAD4 has been observed in a number of neurodegenerative diseases. In this thesis, two broad investigations were undertaken to look at the expression patterns of endogenous PADs and how they provide means to the development of disease modifying treatments. First, a BODIPY-based fluorescent probe was designed to assess the expression levels in vitro and in vivo of endogenous PAD. Secondly, medicinal chemistry approaches were adopted to design a library of novel non-covalent compounds to establish a structure activity relationship on PADs and identify a potential hit. Results indicated that a BODIPY-based biomarker was a feasible approach to monitor PAD enzymes in vivo. Through structure-activity relationship investigations, it was established that small heterocycles on an amino acid side chain were contributing to the inhibitory activities towards PADs. Declaration of Work: All synthetic experiments, synthesis of library of compounds, and confocal microscopy studies were performed by Elizabeth J. Curiel Tejeda. Biological assays and evaluations were performed by Ms. Ewa Wasilewski. ii Acknowledgements I would like thank Dr. Lakshmi Kotra for giving me the opportunity to work in his laboratory and expand my knowledge in the drug development research field. -

Lamers1, Izak Biemond3, Marius A. van den Bergh Weerman6, Dónal O’Carroll7, James C. Hardwick3, Daniel W. Hommes3 & Gijs R. van den Brink1,2,3 In many mammalian species, the intestinal epithelium undergoes major changes that allow a dietary transition from mother’s milk to the adult diet at the end of the suckling period. These complex developmental changes are the result of a genetic programme intrinsic to the gut tube, but its regulators have not been identified. Here we show that transcriptional repressor B lymphocyte-induced maturation protein 1 (Blimp1) is highly expressed in the developing and postnatal intestinal epithelium until the suckling to weaning transition. Intestine-specific deletion of Blimp1 results in growth retardation and excessive neonatal mortality. Mutant mice lack all of the typical epithelial features of the suckling period and are born with features of an adult-like intestine. -

Supplementary Figures Note: Supplementary Tables are provided as separate Excel files. 1. Supplementary Notes 1.1. Religious Orders Study and Memory and Aging Project Gene expression data1. Gene expression data were generated using RNA- sequencing from Dorsolateral Prefrontal Cortex (DLPFC) of 540 individuals, at an average sequence depth of 90M reads. Detailed description of data generation and processing was previously described2 (Mostafavi, Gaiteri et al., under review). Samples were submitted to the Broad Institute’s Genomics Platform for transcriptome analysis following the dUTP protocol with Poly(A) selection developed by Levin and colleagues3. All samples were chosen to pass two initial quality filters: RNA integrity (RIN) score >5 and quantity threshold of 5 ug (and were selected from a larger set of 724 samples). Sequencing was performed on the Illumina HiSeq with 101bp paired-end reads and achieved coverage of 150M reads of the first 12 samples. These 12 samples will serve as a deep coverage reference and included 2 males and 2 females of nonimpaired, mild cognitive impaired, and Alzheimer's cases. The remaining samples were sequenced with target coverage of 50M reads; the mean coverage for the samples passing QC is 95 million reads (median 90 million reads). The libraries were constructed and pooled according to the RIN scores such that similar RIN scores would be pooled together. -

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. -

Its yearling weight and carcass traits (backfat thickness, carcass weight, eye muscle area, and marbling score) are economically important for the selection of young and proven bulls. In recent decades, the advent of high throughput genotyping technologies has made it possible to perform genome-wide association studies (GWAS) for the detection of genomic regions associated with traits of economic interest in different species. In this study, we conducted a weighted single-step genome-wide association study which combines all genotypes, phenotypes and pedigree data in one step (ssGBLUP). It allows for the use of all SNPs simultaneously along with all phenotypes from genotyped and ungenotyped animals. Our results revealed 33 relevant genomic regions related to the traits of interest. -

CXCR4 Pathway Retards Muscle Atrophy During Cancer Cachexia
Oncogene (2016) 35, 6212–6222 © 2016 Macmillan Publishers Limited, part of Springer Nature. All rights reserved 0950-9232/16 www.nature.com/onc ORIGINAL ARTICLE Activation of the SDF1/CXCR4 pathway retards muscle atrophy during cancer cachexia GB Martinelli1, D Olivari1, AD Re Cecconi1, L Talamini1, L Ottoboni2, SH Lecker3, C Stretch4, VE Baracos4, OF Bathe5, A Resovi6, R Giavazzi1, L Cervo7 and R Piccirillo1 Cancer cachexia is a life-threatening syndrome that affects most patients with advanced cancers and causes severe body weight loss, with rapid depletion of skeletal muscle. No treatment is available. We analyzed microarray data sets to identify a subset of genes whose expression is specifically altered in cachectic muscles of Yoshida hepatoma-bearing rodents but not in those with diabetes, disuse, uremia or fasting. Ingenuity Pathways Analysis indicated that three genes belonging to the C-X-C motif chemokine receptor 4 (CXCR4) pathway were downregulated only in muscles atrophying because of cancer: stromal cell-derived factor 1 (SDF1), adenylate cyclase 7 (ADCY7), and p21 protein-activated kinase 1 (PAK1). Notably, we found that, in the Rectus Abdominis muscle of cancer patients, the expression of SDF1 and CXCR4 was inversely correlated with that of two ubiquitin ligases induced in muscle wasting, atrogin-1 and MuRF1, suggesting a possible clinical relevance of this pathway. The expression of all main SDF1 isoforms (α, β, γ) also declined in Tibialis Anterior muscle from cachectic mice bearing murine colon adenocarcinoma or human renal cancer and drugs with anticachexia properties restored their expression. Overexpressing genes of this pathway (that is, SDF1 or CXCR4) in cachectic muscles increased the fiber area by 20%, protecting them from wasting.
