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

    Author : Michael Gralla; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : 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.

  4. 22. Identification of novel genes with important functions in glioblastoma multiforme and acute myeloid leukemia

    Author : Aditya Harisankar; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Glioblastoma multiforme (GBM) is one of the most common and aggressive brain tumors. The cancer stem cells of GBM (GSCs) are notorious for being invasive as well as resistant to radiation and chemotherapy. The current treatment options for GBM lack specificity and result in severe side effects. READ MORE

  5. 23. Functional characterization of the human adenovirus pVII protein and non-coding VA RNAI

    Author : Raviteja Inturi; Tanel Punga; Goran Akusjarvi; Thomas Dobner; Uppsala universitet; []

    Abstract : Human adenovirus (HAdV) is a common pathogen causing a broad spectrum of diseases. HAdV encodes the pVII protein, which is involved in nuclear delivery, protection and expression of viral DNA. To suppress the cellular interferon (IFN) and RNA interference (RNAi) systems, HAdVs encode non-coding virus-associated (VA) RNAs. READ MORE

  6. 24. Unwrapping the role of WRAP53β in DNA damage response

    Author : Hanif Rassoolzadeh; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : WRAP53β is a WD40 domain protein with multifaceted capabilities in several biological processes in different cellular compartments. This includes transportation of the Survival of motor neuron (SMN) complex, small Cajal body-specific (sca) RNAs and the telomerase enzyme to Cajal bodies, as well as targeting of the E3 ligase RNF8 to DNA double-strand breaks (DSBs).

  7. 25. Studies on the mechanisms of action and physiological relevance of SOCS proteins

    Author : Fahad Al-Zadjali; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Understanding systemic biological pathways and the key cellular mechanisms that dictate disease states, drug response, and altered cellular function in metabolic disorders is a significant challenge. Research in the last 20 years have made it clear that tissue communication, through the actions of endocrine, paracrine or autocrine factors play a significant role in pathogenesis of complex multiorgan diseases such as the metabolic syndrome.
