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

    Author : Erik A. Pelve; Rolf Bernander; Sonja Verena Albers; Uppsala universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 2. Imaging Living Cells with an X-ray Laser

    Author : Gijs van der Schot; Tomas Ekeberg; Janos Hajdu; Filipe Maia; Pierre Thibault; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Coherent diffractive X-ray imaging; flash X-ray imaging; lensless imaging; single particle imaging; cyanobacteria; phasing; image classification; substrate-free sample delivery; X-ray free-electron laser; XFEL; FEL; CDXI; CDI; CXI; FXI; Chemistry with specialization in Biophysics; Kemi med inriktning mot biofysik;

    Abstract : Imaging living cells at a resolution higher than the resolution of optical microscopy is a significant challenge. Fluorescence microscopy can achieve a degree of super-resolution via labeling cellular components with a fluorescent dye. READ MORE

  5. 3. Colorectal cancer and radiation response : The role of EGFR, AKT and cancer stem cell markers

    Author : Sara Häggblad Sahlberg; Bo Stenerlöw; Bengt Glimelius; Marika Nestor; Torgny Stigbrand; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colorectal cancer; radiation; AKT; EGFR; cancer stem cells; CD133; CD44; Biomedical Radiation Science; Biomedicinsk strålningsvetenskap; Biologi med inriktning mot molekylär cellbiologi; Biology with specialization in Molecular Cell Biology;

    Abstract : The primary treatment for colorectal cancer is surgery. Radiotherapy and chemotherapy, sometimes combined, are also frequently used to diminish recurrence risk. In response to radiation exposure, several cellular signaling cascades are activated to repair DNA breaks, prevent apoptosis and to keep the cells proliferating. READ MORE

  6. 4. Mechanisms for Quantitative Regulation of TGF-ß Signaling

    Author : Markus Dahl; Aristidis Moustakas; Carl-Henrik Heldin; Daniel Constam; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biologi med inriktning mot molekylär cellbiologi; Biology with specialization in Molecular Cell Biology;

    Abstract : Cancer is a widely spread disease, and many cancer variants are today still difficult to treat. Efforts are being made to understand the complexity of cancer, both at a clinical level but also at a pre-clinical level. READ MORE

  7. 5. Tailoring Fluorescent Probes for Organelle-Specific Imaging and Sensing

    Author : Xin Zhang; Zhangjun Hu; Kajsa Uvdal; Fredrik Almquist; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Fluorescent imaging; Ratiometric Nanoprobe; Autophagy; Apoptosis; FRET; Fluorescerande avbildning; Ratiometric Nanoprobe; Autophagy; Apoptosis; FRET;

    Abstract : Exploring and visualizing biological and pathological processes in living cells are useful for both fundamental research and applications. An understanding on the molecular level for these processes with focus on tracking biomarkers, collecting information about their surroundings, and uncovering essential molecular pathways and functions in live cells are of vital interest for cell biological study and clinical diagnosis application.
