  1. 1. Control of reactive oxygen species homeostasis in response to environmental stress

    Författare :Malgorzata Plaszczyca; Katharina Pawlowski; Jean-Jacques Drevon; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stress; antioxidant defense; ascorbate peroxidase; aerenchyma; actinorhiza; Plant physiology; Växtfysiologi; Plant Physiology; växtfysiologi;

    Sammanfattning : Plants are exposed to various fluctuations in their environmental conditions - light intensity, temperature, water status - and have to adapt in order to survive. Plant acclimatory responses can include the formation of new tissues, e.g., aerenchyma, or the activation of defense systems, e. LÄS MER

  3. 2. Bioactive nanocellulose materials for the treatment of chronic wounds

    Författare :Anna Blasi Romero; Natalia Ferraz; Daniel Aili; Uppsala universitet; []

    Sammanfattning : Chronic wounds represent a burden for the healthcare system and significantly affect the quality of life of the patients. There is currently a lack of efficient treatments but new, improved therapeutic approaches are under development. LÄS MER

  4. 3. Mammalian thioredoxin reductase 1 in antioxidant defense, regulation of adipocyte differentiation and as an anticancer drug target

    Författare :Xiaoxiao Peng; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Reactive oxygen species (ROS) are oxygen containing reactive molecules generated as by-products of cellular metabolism. At physiological concentrations, ROS acts as secondary messengers in cellular signaling transduction, but excessive amounts of ROS result in oxidative stress and cellular damage. LÄS MER

  5. 4. Cell-Penetrating Peptides for Mitochondrial Targeting

    Författare :Carmine Pasquale Cerrato; Ülo Langel; Shana O. Kelley; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mitochondrial targeting; cell-penetrating peptides; antioxidant activity; scavenging ability; oligonucleotide delivery; neurokemi med molekylär neurobiologi; Neurochemistry with Molecular Neurobiology;

    Sammanfattning : Mitochondria have simply been known as the cell’s powerhouse for a long time, with its vital function of producing ATP. However, substantially more attention was directed towards these organelles once they were recognized to perform several essential functions having an impact in cell biology, pharmaceutics and medicine.

  7. 5. The impact of cytochrome P4501-inhibitors on aryl hydrocarbon receptor signaling

    Författare :Johanna Bengtsson; Emma Wincent; Ulf Rannug; Malin Celander; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : The aryl hydrocarbon receptor (AHR) best known as a ligand-activated transcription factor that mediates toxic responses to xenobiotics such as dioxins, is also activated by certain endogenous compounds. Activation of the AHR up-regulates transcription of a large number of genes, including those encoding members of the cytochrome P450 1 family of enzymes (CYP1s). LÄS MER
