英文摘要:

Chemotherapeutic agents- and radiation therapy-induced NF-kappa B activation in cancer cells contributes to aggressive tumor growth and resistance to chemotherapy and ionizing radiation during cancer treatment. TAXI has been shown to be required for genotoxic stress-induced NF-kappa B activation. However, whether TAK1 ubiquitination is involved in genotoxic stress-induced NF-kappa B activation remains unknown. Herein, we demonstrate that TAXI ubiquitination plays an important role in the positive and negative regulation of doxorubicin (Dox)-induced NF-kappa B activation. We found that TAXI was required for Dox-induced NF-kappa B activation. At the early stage of Dox treatment, Dox induced Lys63-linked TAK1 polyubiquitination at lysine 158 residue. USP4 inhibited Dox-induced TAXI Lys63-linked polyubiquitination and knockdown of USP4 enhanced Dox-induced NF-kappa B activation. At the late stage of Dox treatment, Dox induced Lys48-linked TAK1 polyubiquitination to promote TAXI degradation. ITCH inhibited Dox-induced NF-kappa B activation by promoting Lys48-linked TAXI polyubiquitination and its subsequent degradation. Our study indicates that TAXI ubiquitination plays critical roles in the regulation of Dox-induced NF-kappa B activation. Thus, intervention of TAXI kinase activity or TAK1 Lys63-linked polyubiquitination pathways might greatly enhance the therapeutic efficacy of Dox. (C) 2012 Elsevier Inc. All rights reserved.
