Abstract RNA splicing, transcription and the DNA damage response are intriguingly linked in mammals but the underlying mechanisms remain poorly understood. Using an in vivo biotinylation tagging approach in mice, we show that the splicing factor XAB2 interacts with the core spliceosome and that it binds to spliceosomal U4 and U6 snRNAs and pre-mRNAs in developing livers. -

Number 3 March 2016 Atlas of Genetics and Cytogenetics in Oncology and Haematology
Volume 1 - Number 1 May - September 1997 Volume 20 - Number 3 March 2016 Atlas of Genetics and Cytogenetics in Oncology and Haematology OPEN ACCESS JOURNAL INIST-CNRS Scope The Atlas of Genetics and Cytogenetics in Oncology and Haematologyis a peer reviewed on-line journal in open access, devoted to genes, cytogenetics, and clinical entities in cancer, and cancer-prone diseases. It is made for and by: clinicians and researchers in cytogenetics, molecular biology, oncology, haematology, and pathology. One main scope of the Atlas is to conjugate the scientific information provided by cytogenetics/molecular genetics to the clinical setting (diagnostics, prognostics and therapeutic design), another is to provide an encyclopedic knowledge in cancer genetics. The Atlas deals with cancer research and genomics. It is at the crossroads of research, virtual medical university (university and post-university e-learning), and telemedicine. It contributes to "meta-medicine", this mediation, using information technology, between the increasing amount of knowledge and the individual, having to use the information. Towards a personalized medicine of cancer. It presents structured review articles ("cards") on: 1- Genes, 2- Leukemias, 3- Solid tumors, 4- Cancer-prone diseases, and also 5- "Deep insights": more traditional review articles on the above subjects and on surrounding topics. It also present 6- Case reports in hematology and 7- Educational items in the various related topics for students in Medicine and in Sciences. The Atlas of Genetics and Cytogenetics in Oncology and Haematology does not publish research articles.

Mrna Editing, Processing and Quality Control in Caenorhabditis Elegans
| WORMBOOK mRNA Editing, Processing and Quality Control in Caenorhabditis elegans Joshua A. Arribere,*,1 Hidehito Kuroyanagi,†,1 and Heather A. Hundley‡,1 *Department of MCD Biology, UC Santa Cruz, California 95064, †Laboratory of Gene Expression, Medical Research Institute, Tokyo Medical and Dental University, Tokyo 113-8510, Japan, and ‡Medical Sciences Program, Indiana University School of Medicine-Bloomington, Indiana 47405 ABSTRACT While DNA serves as the blueprint of life, the distinct functions of each cell are determined by the dynamic expression of genes from the static genome. The amount and specific sequences of RNAs expressed in a given cell involves a number of regulated processes including RNA synthesis (transcription), processing, splicing, modification, polyadenylation, stability, translation, and degradation. As errors during mRNA production can create gene products that are deleterious to the organism, quality control mechanisms exist to survey and remove errors in mRNA expression and processing. Here, we will provide an overview of mRNA processing and quality control mechanisms that occur in Caenorhabditis elegans, with a focus on those that occur on protein-coding genes after transcription initiation. In addition, we will describe the genetic and technical approaches that have allowed studies in C. elegans to reveal important mechanistic insight into these processes.

Exploring Potential Germline-Associated Roles of the TRIM-NHL Protein NHL-2 Through Rnai Screening
MUTANT SCREEN REPORT Exploring Potential Germline-Associated Roles of the TRIM-NHL Protein NHL-2 Through RNAi Screening Gregory M. Davis,*,† Wai Y. Low,*,1 Joshua W. T. Anderson,*,‡ and Peter R. Boag*,‡,2 *Department of Biochemistry and Molecular Biology, Monash University, Clayton, Victoria 3800, Australia, †School of Applied and Biomedical Sciences, Federation University, Churchill, Victoria 3842, Australia, and ‡Development and Stem Cells Program, Monash Biomedicine Discovery Institute, Clayton, Victoria 3800, Australia ABSTRACT TRIM-NHL proteins are highly conserved regulators of developmental pathways in vertebrates KEYWORDS and invertebrates. The TRIM-NHL family member NHL-2 in Caenorhabditis elegans functions as a miRNA NHL-2 cofactor to regulate developmental timing. Similar regulatory roles have been reported in other model TRIM-NHL systems, with the mammalian ortholog in mice, TRIM32, contributing to muscle and neuronal cell pro- RNAi screen liferation via miRNA activity. Given the interest associated with TRIM-NHL family proteins, we aimed to germline further investigate the role of NHL-2 in C. elegans development by using a synthetic RNAi screening Caenorhabditis approach. Using the ORFeome library, we knocked down 11,942 genes in wild-type animals and nhl-2 null elegans mutants. In total, we identified 42 genes that produced strong reproductive synthetic phenotypes when Mutant Screen knocked down in nhl-2 null mutants, with little or no change when knocked down in wild-type animals. Report These included genes associated with transcriptional processes, chromosomal integrity, and key cofactors of the germline small 22G RNA pathway. TRIM-NHL proteins are highly conserved and are required for several (Neumuller et al. -

CANCER GENOMICS & PROTEOMICS 11 : 81-92 (2014) A Novel Transmembrane Glycoprotein Cancer Biomarker Present in the X Chromosome ANA PAULA DELGADO, SHEILIN HAMID, PAMELA BRANDAO and RAMASWAMY NARAYANAN Department of Biological Sciences, Charles E. Schmidt College of Science, Florida Atlantic University, Boca Raton, FL, U.S.A. Abstract. Background: The uncharacterized proteins of the genome are of unknown nature (10). These proteins and the human proteome offer an untapped potential for cancer non-coding RNAs are called the ‘dark matter’ of the genome biomarker discovery. Numerous predicted open reading (11-13). Whereas in the past most gene discovery has frames (ORFs) are present in diverse chromosomes. The revolved around known genes due to the ease of follow-up mRNA and protein expression data, as well as the mutational studies (14-17), the dark matter of the genome offers an and variant information for these ORF proteins are available untapped potential (18). Realizing the importance of this area, in the cancer-related bioinformatics databases. Materials the US National Cancer Institute has recently announced a and Methods: ORF proteins were mined using bioinformatics major initiative called illuminating the dark matter for and proteomic tools to predict motifs and domains, and druggable targets (http://commonfund.nih.gov/idg/index). cancer relevance was established using cancer genome, Establishing cancer relevance for novel or uncharacterized transcriptome and proteome analysis tools. Results: A novel proteins is a crucial first step in lead discovery. The cancer testis-restricted ORF protein present in chromosome X called genomes of patients from around the world can be readily CXorf66 was detected in the serum, plasma and neutrophils. -
