英文摘要Aberrant regulation of nuclear factor kappa B (NF-?B) transcription factor is involved in cancer development, progression and resistance to chemotherapy. JG3, a marine-derived oligomannurarate sulfate, was reported as a heparanase and NF-?B inhibitor to significantly block tumor growth and metastasis in various animal models. However, the detailed functional mechanism remains unclear. Here, we report that JG3 inhibits NF-?B activation by specifically antagonizing the doxorubicin-triggered Ataxia-telangiectasia-mutated kinase (ATM) and the sequential MEK/ERK/p90Rsk/IKK signaling pathway but does not interfere with TNF-a-mediated NF-?B activation. This selective inactivation of the specific NF-?B cascade is attributed to the binding capacity of JG3 for Mre11, a major sensor of DNA double-strand breaks (DSB). Based on this selective mechanism, JG3 showed synergistic effect with doxorubicin in a panel of tumor cells and did not affect immune system function as shown in the in vivo delayed-type hypersensitivity (DTH) and hemolysis assays. All these highlight the clinical potential of JG3 as a favorable sensitizer in cancer therapy. In addition, identification of Mre11 as a potential target in the development of NF-?B inhibitors provides a platform for the further development of effective anticancer agents.
