  1. 11. Understanding the Noise : Spliceosomal snRNA Profiling

    Författare :Lei Liu Conze; Anders Virtanen; Lars Wieslander; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ncRNA; snRNA; U1; splice site; alternative splicing; high-throughput sequencing; 454; SNP; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : The concept of the gene has been constantly challenged by new discoveries in the life sciences. Recent challenging observations include the high frequency of alternative splicing events and the common transcription of non-protein-coding-RNAs (ncRNAs) from the genome. The latter has long been considered noise in biological systems. LÄS MER

  2. 12. Regulation of RNA Editing : The impact of inosine on the neuronal transcriptome

    Författare :Mikaela Behm; Marie Öhman; André Gerber; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; RNA editing; ADAR; miRNA; Neuron; Brain development; Synapse; Molecular Biology; molekylärbiologi;

    Sammanfattning : The transcriptome of the mammalian brain is extensively modified by adenosine to inosine (A-to-I) nucleotide conversion by two adenosine deaminases (ADAR1 and ADAR2). As adenosine and inosine have different base pairing properties, A-to-I RNA editing shapes the functional output of both coding and non-coding RNAs (ncRNAs) in the brain. LÄS MER

  3. 13. A small amoeba at the crossroads of the big RNAi world : MicroRNA biogenesis and Argonaute function in Dictyostelium discoideum

    Författare :Zhen Liao; Fredrik Söderbom; Gerhart E. H. Wagner; Christina Dixelius; Kriton Kalantidis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; RNAi; microRNA; Argonaute protein; miRNA biogenesis; Dictyostelium discoideum; social amoeba; Dicer; development; growth; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : Small non-coding RNA (ncRNA) mediated gene silencing, known as RNAi, is a key regulatory mechanism of gene expression in eukaryotes. MicroRNAs (miRNA), one major type of small ncRNAs, are about 21nt long and bound by Argonaute proteins. LÄS MER

  4. 14. Functional analysis of long non-coding RNAs in cancer

    Författare :Linda Vidarsdottir; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : For years the functional role of noncoding RNAs was greatly underestimated. Whole genome RNA sequencing projects that unraveled pervasive transcription emitting from large parts of the human genome changed those perspectives and prompted scientists to further look into the involvement of noncoding RNAs (ncRNAs) in development and disease.

  5. 15. PARN - A Tale of A de-Tailor : Functional importance of poly(A) degradation in developmental and telomere biology disorders

    Författare :Sethu Madhava Rao Gunja; Anders Virtanen; Jonas von Hofsten; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PARN; Telomere biology disorders; snoRNAs; scaRNAs; TR TERC; Zebrafish; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi; Molekylär genetik; Molecular Genetics; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Poly(A)-specific ribonuclease (PARN) is a eukaryotic 3’-5’exoribonuclease that removes poly(A) tails of many coding and non-coding RNAs. In this thesis, we have studied the physiological role of PARN. LÄS MER
