  1. 1. Small non-coding RNAs in cancer

    Författare :Helena Persson; Bröstcancer-genetik; []

    Sammanfattning : The complex genetics of cancer, which allows tumours to grow and spread while bypassing the control circuitry of the cell, involves dysregulation of the genome, transcriptome and proteome. The importance of protein-coding genes such as growth factors and hormone receptors is well established. LÄS MER

  2. 2. Computational identification of non-coding RNAs

    Författare :Paul Piccinelli; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :RNase P; RNase MRP; IRE; non-coding RNA; secondary structure;

    Sammanfattning : A large amount of genomic information is now becoming available. Suitable bioinformatic tools to organize and analyze this vast amount of information are therefore important. In the case of protein genes, the majority of these may be correctly identified using standard search methods that are based on sequence alignment. LÄS MER

  3. 3. Adenoviral small non-coding RNAs : A Structural and Functional Charaterization

    Författare :Wael Kamel; Göran Akusjärvi; Ben Berkhout; Uppsala universitet; []
    Nyckelord :non-coding RNA miRNA mivaRNA canonical Dicer Ago2 TSS m7G Cap Adenovirus replication E2B;

    Sammanfattning : Since their discovery in 1953, adenoviruses have significantly contributed to the understanding of virus-host cell interactions, including mechanistic details of cellular processes such as cell cycle control and alternative RNA splicing. Among the first characterized adenoviral genes were the virus-associated RNAs (VA RNAI/II), which are produced in massive amount during a lytic infection. LÄS MER

  4. 4. The deep evolutionary roots of non-coding RNA - a comparative genomics approach

    Författare :Marc Patrick Hoeppner; Anthony M. Poole; Britt-Marie Sjöberg; Jürgen Brosius; Stockholms universitet; []
    Nyckelord :MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; non-coding RNA; evolution; comparative genomics; RNA world; introns; snoRNA; miRNA; Molecular biology; Molekylärbiologi; Molecular Biology; molekylärbiologi;

    Sammanfattning : Non-coding RNAs (ncRNA) are a diverse group of genes that do not encode proteins but function exclusively on the level of RNA and were originally suggested to be remnants of a pre-DNA stage of life known as the RNA world. More recent work, however, has uncovered a rich repertoire of previously unknown families with possible consequences for our understanding of the origin and evolution of the modern RNA infrastructure.

  5. 5. Non-protein-coding RNA : Transcription and regulation of ribosomal RNA

    Författare :Stefanie Böhm; Ann-Kristin Östlund Farrants; Brian McStay; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; ribosomal RNA; non-coding RNA; ribosomal genes; rDNA gene; B-WICH; chromatin remodelling; histone modification; Cell Biology; cellbiologi;

    Sammanfattning : Cell growth and proliferation are processes in the cell that must be tightly regulated. Transcription of ribosomal RNA and ribosomal biogenesis are directly linked to cell growth and proliferation, since the ribosomal RNA encodes for the majority of transcription in a cell and ribosomal biogenesis influences directly the number of proteins that are synthesized.
