  • Title: Theileria-induced constitutive IKK activation is independent of functional Hsp90.
    Author: Hermann P, Dobbelaere DA.
    Journal: FEBS Lett; 2006 Sep 18; 580(21):5023-8. PubMed ID: 16938294.
    Abstract:
    The intracellular parasite Theileria induces uncontrolled proliferation and host cell transformation. Parasite-induced transformation is accompanied by constitutive activation of IkappaB kinase (IKK), resulting in permanently high levels of activated nuclear factor (NF)-kappaB. IKK activation pathways normally require heat shock protein 90 (Hsp90), a chaperone that regulates the stability and activity of signalling molecules and can be blocked by the benzoquinone ansamycin compound geldanamycin (GA). In Theileria-transformed cells, IkappaBalpha and p65 phosphorylation, NF-kappaB nuclear translocation and DNA binding activity are largely resistant to GA and also NF-kappaB-dependent reporter gene expression is only partly affected. Our findings indicate that parasite-induced IKK activity does not require functional Hsp90.
