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

    Author : Sethu Madhava Rao Gunja; Anders Virtanen; Jonas von Hofsten; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; MEDICAL AND HEALTH 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;

    Abstract : 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. READ MORE

  4. 2. Surviving the ratchet : Modelling deleterious mutations in asexual populations

    Author : Jonas Söderberg; Otto Berg; Laurence Loewe; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; Theoretical biology; Population genetics; Stochastic modelling; Genome evolution; Muller s Ratchet; Genetics; Genetik; Organism biology; Organismbiologi; Biology; Biologi; Biologi med inriktning mot molekylär evolution; Biology with specialization in Molecular Evolution;

    Abstract : One of the most unforgiving processes in nature is that of Muller's ratchet, a seemingly irreversible accumulation of deleterious mutations that all organisms have to deal with or face extinction. The most obvious way to avoid fitness collapse is recombination, though asexual populations usually do not have the luxury of recombining freely. READ MORE

  5. 3. Genomic adaptation and gene-dosage regulation of Drosophila melanogaster cells, and long-read software developments

    Author : Jacob Lewerentz; Per Stenberg; Jan Larsson; Bergman Casey; Umeå universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; Drosophila; cell line; long read; Nanopore; Pacbio; Illumina; cancer; genome evolution; dosage compensation; structural variant; software; bioinformatics;

    Abstract : Cells are the vehicles that allows genetic code to proliferate in the world, taking on various forms – as illustrated by the tree of life. The cell features are determined by the manufacturing of proteins, a process that has its blueprints encoded as genes in the genome. READ MORE

  6. 4. Development of Computational Methods for Cancer Research: Strategies for closing the feedback loop in omics workflows

    Author : Ufuk Kirik; Institutionen för immunteknologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES; MEDICAL AND HEALTH SCIENCES; cancer; proteome profiling; bioinformatics; pathway analysis; mass spectrometry; Quantitative proteomics;

    Abstract : As the ultimate workhorses of the living things, proteins undergo significant regulatory activity throughout the lifetime of a cell or an organism. Many complex diseases effect the protein composition, expression or modification in the cells or tissues they arise in. READ MORE

  7. 5. Chromatin regulators and transcriptional control of Drosophila development

    Author : Qi Dai; Mattias Mannervik; Albert J. Courey; Stockholms universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Chromatin; Co-factors; Transcription; Development; Drosophila; Developmental biology; Utvecklingsbiologi; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : The development of a multicellular organism is programmed by complex patterns of gene expression. In eukaryotic cells, genes are packaged by histone proteins into chromatin. Chromatin regulators often function as transcription co-factors. READ MORE
