  1. 6. Molecular studies of Wig-1, a p53-induced zinc finger protein

    Författare :Cristina Méndez Vidal; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The fact that p53 is one of the most commonly mutated gene in human tumors indicates that it has a key role in tumor suppression. p53 accumulates after DNA-damage and other types of cellular stress, leading to the initiation of a p53-dependent biological response, including cell cycle arrest and apoptosis.

  3. 7. Structural Decorations in Viruses : Unraveling Acquired Functional Structures in Icosahedral RNA Virus Capsids

    Författare :Han Wang; Kenta Okamoto; Sarah Butcher; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Viruses; RNA viruses; capsid; structure; cryo-EM; Molekylär biovetenskap; Molecular Life Sciences;

    Sammanfattning : Viruses have a profound impact worldwide, posing challenges to animal welfare, agriculture, human health, and the ecosystem. This thesis examines the realm of non-enveloped icosahedral double-stranded (ds)RNA and single-stranded (ss)RNA viruses through three studies. LÄS MER

  4. 8. The p53-induced gene wig-1 : regulation of expression and role in embryonic development

    Författare :Margareta Wilhelm; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The p53 tumor suppressor is a transcription factor that responds to various forms of cellular stress. Activated p53 induces growth arrest or apoptosis through transcriptional regulation of a wide range of target genes. More than 50% of human tumors carry mutations in the p53 gene, most of which reside within the DNAbinding core domain of p53. LÄS MER

  5. 9. Systemic RNAi Relies on the Endomembrane System in Caenorhabditis elegans

    Författare :Yani Zhao; Andrea Hinas; Staffan Svärd; Simon Tuck; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systemic RNAi; RNAi inheritance; late endosomes MVBs; SID-5; SEC-22; SYX-6; C12D8.1; Biology with specialization in Molecular Biology; Biologi med inriktning mot molekylärbiologi;

    Sammanfattning : The membrane system of a eukaryotic cell is a large and complex system handling the transport, exchange and degradation of many kinds of material. Recent research shows that double-stranded RNA (dsRNA) mediated gene silencing (RNA interference) is a membrane related process. LÄS MER

  7. 10. Effects of the host defense peptide LL-37 on human cells : Immunomodulation and cytotoxicity

    Författare :Sara Bodahl; Kärlfysiologi; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LL-37; Host defense peptides; Cathelicidin; Inflammation; Cytotoxicity; TLR3; Poly I:C;

    Sammanfattning : The human host defense peptide LL-37 has an essential role in the first line of defense against invading pathogens. This cathelicidin is mainly produced by immune cells and epithelial cells aligning the mucosal areas and is normally upregulated upon infection and inflammation. LÄS MER
