Project description:Mucin 1 (MUC1) is a transmembrane mucin expressed at the apical surface of epithelial cells at different mucosal surfaces including breast and intestine. The MUC1 extracellular domain contains a variable number of tandem repeats (VNTR) of 20 amino acids, which are heavily O-linked glycosylated. Monoclonal antibodies against the MUC1 VNTR can be powerful tools because of their multiplicity of binding and possible applications in the diagnosis and treatment of MUC1-expressing cancers. One such antibody is the hybridoma mouse monoclonal 139H2 which is also widely used as a research tool to study non-cancer MUC1. Here we report direct mass spectrometry-based sequencing of hybridoma-derived 139H2 IgG, which enabled reverse engineering of a recombinant 139H2.

Project description:Supplemental data for the article: Characterization of functional reprogramming during osteoclast development using quantitative proteomics and mRNA profiling Eunkyung An, Manikandan Narayanan, and Aleksandra Nita-Lazar* *corresponding author: Cellular Networks Proteomics Unit Laboratory of Systems Biology National Institute of Allergy and Infectious Diseases National Institutes of Health Bethesda, Maryland, 20892, USA Tel. +1 301-451-4394 Fax: +1 301-480-5170 E-mail: nitalazarau@niaid.nih.gov This dataset includes: 1. Raw LC-MS(/MS) spectra (*.raw), and 2. The output from data analyses using IP2 (Intergrated Proteomics Application, San Diego, CA) searched against the UniProt_mouse_01-18-2011 set of protein sequences (normal + reversed). Note that the version of IP2 that was used could only analyze two SILAC channels at a time, so two analyses were performed (light-medium, light-heavy) (the current version can analyze 3-plex SILAC all together in one analysis). Also, IP2 was run using two criteria (1 or 2 peptides per protein). Lanes D and E were lanes of an SDS-PAGE gel, and each was 3-plex SILAC: Lane D: Light (Osteoclast Precursor), Medium (Mature Osteoclast), Heavy (Intermediate Osteoclast) Lane E: Light (Osteoclast Precursor), Medium (Intermediate Osteoclast), Heavy (Mature Osteoclast)
Project description:Genome-wide methylation profiles were generated as part of a multi-omics characterization (SNP array, WES, RNA-seq, cDNA microarray) of a panel of gliomasphere cell lines and matched parental tumors. See https://www.ncbi.nlm.nih.gov/pubmed/27571888 about the GlioTeX panel. Methylation profiling data in this record come from tumour samples. SNP array (ArrayExpress E-MTAB-4804), cDNA microarray (ArrayExpress E-MTAB-4803), WES and RNAseq (European Genome-Phenome Archive EGAS00001001871) have been published before. In addition, for the current project we compare 450K methylation data to nanopore sequencing based methylation profiles. These sequencing data will be accessible via European Genome-Phenome Archive (EGAS00001002213).

Project description:Mycothiol (MSH) and ergothioneine (ERG) are thiols able to compensate for each other to protect mycobacteria such as Mycobacterium smegmatis against oxidative stress. Gamma-glutamylcysteine (GGC), another thiol and an intermediate in ERG biosynthesis has detoxification abilities. Five enzymes are involved in ERG biosynthesis, namely EgtA, EgtB, EgtC, EgtD and EgtE. The role of these enzymes in the production of ERG had been unclear. On the other hand, the enzyme MshA is known to be essential for MSH biosynthesis. In this manuscript, we describe the raw data of the generation and characterization of Mycobacterium tuberculosis (M.tb) mutants harbouring a deletion of the gene coding for each of these enzymes, and the raw data of the phenotypic characterization of the obtained thiol-deficient M.tb mutants. Through a high throughput screening approach, compounds not previously used in a tuberculosis (TB) regimen were identified. Raw data depicting the effect of these compounds on the generated thiol-deficient M.tb mutants, on the production of reactive oxygen species (ROS) and thiols in the M.tb wild type strain are described in this study.
