  1. 21. Identification of novel pathways of regulation of AHR and HIF-­1 function

    Författare :Michael Gralla; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Mammalian bHLH-Pas (basic HLH (helix-loop-helix)-PER-ARNT-SIM) proteins belong to the bHLH superfamily of transcription factors. Members of the family have a broad spectrum of functions that among others sense and regulate the cellular response to physiological signals such as low oxygen levels (hypoxia), or environmental signals such as toxins.

  3. 22. Induction of type I interferons and viral immunity

    Författare :Åsa Hidmark; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Virus-induced type I interferons (IFNα/β) are key mediators of innate immunity and important modulators of adaptive immunity. Early recognition of virus and induction of IFNα/β are important for limiting the spread of the virus. LÄS MER

    Sammanfattning : Hepatocellular carcinoma (HCC) is one of the most prevalent cancer types in the Western world and in the Asia-pacific regions, with its incidence expected to rise up to 22 million cases till 2020. Hepatocellular carcinoma etiology is mainly due to hepatitis B (HBV) and hepatitis C (HCV) infections, and to a lesser extent it is determined by the development of alcohol-driven cirrhosis and non-alcoholic steatohepatitis (NASH).

  5. 24. Effects of Alzheimer's and Parkinson's disease gene mutation on cell signaling

    Författare :Nodi Dehvari; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Alzheimer's disease (AD) and Parkinson's disease (PD) are the major neurodegenerative disorders affecting the elderly. The discovery of genes causing familial forms of these disorders has contributed enormously towards our understanding of underlying pathogenic mechanisms. LÄS MER

    Sammanfattning : Neuroblastoma (NB) is a tumor of the sympathetic nervous system and is the most common extra-cranial tumor of childhood, accounting for 7% of all pediatric malignancies. Despite recent advances in therapeutics, outcome is still fatal for patients with aggressive NB and side-effects of treatment are severe. LÄS MER
