  1. 1. Unique Solutions to Universal Problems : Studies of the Archaeal Cell

    Författare :Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Archaea; Cdv; Cell cycle; Cell division; Cell lysis; Crenarchaea; ESCRT-III; Flow cytometry; Microarray; Microscopy; Nitrosopumilus; SIRV2; Sulfolobus; Thaumarchaea; Transcription; VAP; Virus; Biology with specialization in Molecular Evolution; Biologi med inriktning mot molekylär evolution;

    Sammanfattning : Archaea is one of the three domains of life and studies of archaeal biology are important for understanding of life in extreme environments, fundamental biogeochemical processes, the origin of life, the eukaryotic cell and their own, unique biology. This thesis presents four studies of the archaeal cell, using the extremophilic Sulfolobus and ocean living Nitrosopumilus as model systems. LÄS MER

  3. 2. Molecular insights into primer removal during mtDNA replication

    Författare :Ali Al-Behadili; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; Mitochondrial DNA replication; DNA replication; Primer removal; RNase H1; Primer formation; Replication initiation; mitochondrial diseases;

    Sammanfattning : Mitochondria are vital for cell survival, and the primary producers of ATP, the energy currency used for various metabolic processes. Mitochondria are unique from other cellular compartments because they have their own genomes of circular small double-stranded DNA (mtDNA) of approximately 16. LÄS MER

  4. 3. Regulation of Human Mitochondrial DNA Replication and Transcription

    Författare :Majda Mehmedovic; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Mitochondria; mtDNA; replication; transcription; TFAM;

    Sammanfattning : Mitochondria are organelles in eukaryotic cells, which through oxidative phosphorylation (OXPHOS) produce most of the ATP used to drive cellular processes. The organelle contains its own genetic material, mitochondrial DNA (mtDNA), which encodes 13 key components of the OXPHOS machinery. LÄS MER

  5. 4. Protein tyrosine kinases in insulin producing cells : Expression and putative importance for beta-cell function

    Författare :Charlotte Öberg-Welsh; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Protein tyrosine kinase; insulin producing cells; fetal development; VEGF; Src-family; Bsk; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Sammanfattning : Protein tyrosine kinases are of importance for cell replication and differentiation in manysystems. The mechanisms controlling the replication and differentiation of insulin producingcells are unknown. LÄS MER

  7. 5. Exploring the Cell Cycle of Archaea

    Författare :Magnus Lundgren; Rolf Bernander; William Margolin; Uppsala universitet; []
    Nyckelord :Microbiology; Archaea; Cell cycle; Replication; Mitosis; Cell division; Mikrobiologi;

    Sammanfattning : Archaea is the third domain of life, discovered only thirty years ago. In a microscope archaea appear indistinguishable from bacteria, but they have been shown to be more closely related to eukaryotes than to bacteria. Especially central information processing is homologous to that of eukaryotes. LÄS MER
