    Sammanfattning : High-throughput drug screening (HTS) in live cells is often a vital part of the preclinical anticancer drug discovery process. So far, two-dimensional (2D) monolayer cell cultures have been the most prevalent model in HTS endeavors. However, 2D cell cultures often fail to recapitulate the complex microenvironments of in vivo tumors. LÄS MER

  2. 2. Structural and functional studies of protein complexes involved in energy metabolism

    Författare :Jens Berndtsson; Martin Ott; Irene Diaz-Moreno; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mitochondria; metabolism; OXPHOS; yeast respiratory supercomplex; cytochrome c; coenzyme Q; pyruvate dehydrogenase complex; Biochemistry; biokemi;

    Sammanfattning : Mitochondria are eukaryotic organelles with a multitude of functions including biosynthesis of molecules and cellular regulation. Most prominently though is their role in energy conversion which culminates with the production of ATP, the universal molecular unit of currency. LÄS MER

  3. 3. The significance of mitochondrial respiratory function in regulating oxygen uptake and performance in humans

    Författare :Daniele A. Cardinale; Filip J Larsen; David Bishop; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mitochondria; OXPHOS; p50mito; mitochondrial oxygen affinity; oxygen extraction; sex difference; hyperoxia; training; muscle metabolism; performance; HIIT; Medicin Teknik; Medicine Technology;

    Sammanfattning : The mitochondrion is one of the most fascinating organelles of our cells which has kept and keeps researchers busy in studying its origin, the complex morphology, the numerous functions, the rapid adaptations to a variety of stimuli and its role in health and disease. Exercise challenges cellular homeostasis and skeletal muscle mitochondria greatly adapt to repeated bouts of exercise by increasing mitochondrial respiratory function and content to match energy requirements and to better sustain future perturbations induced by muscle contractions.

  4. 4. Skeletal muscle fiber types in man : With special reference to anabolic signaling and mitochondrial bioenergetics

    Författare :Sebastian Edman; William Apro; Filip J Larsen; Abram Katz; Leigh Breen; Gymnastik- och idrottshögskolan; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mTORC1; THRIFTY; fiber type identification; muscle growth; aging; sarcopenia; mitochondrial function; oxphos; metabolism; Medicin Teknik; Medicine Technology;

    Sammanfattning : Human skeletal muscle consists of a mixture of slow-twitch (type I) and fast-twitch (type II) fibers. The type I fibers are endurance-oriented, with a metabolic system and infrastructure that supports aerobic metabolism. LÄS MER

  5. 5. Quiescent cancer cells : Three-dimensional cell models for evaluation of new therapeutics

    Författare :Frida Ek; Mårten Fryknäs; Malin Jarvius; Rolf Larsson; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cancer; cancer cell quiescence; dormancy; three-dimensional; multicellular tumor spheroids; model development; cancer pharmacology; mitochondria; OXPHOS; colorectal carcinoma; hepatocellular carcinoma; Medicinsk vetenskap; Medical Science;

    Sammanfattning : Inadequate metabolic conditions in solid tumors lead to the formation of quiescent cancer cells that are suspended in a transient cell cycle arrest. When conditions change, quiescent cancer cells can re-enter the cell cycle and cause recurrence. LÄS MER
