描述 | The NF-kB pathway plays a key role in multiple cellular processes, including immune signaling, inflammation, development, proliferation and survival. NF-κB suppression occurred through inhibition, activation, phosphorylation and degradation of IκB-α, p65 phosphorylation, p65 nuclear translocation, and NF-κB-mediated reporter gene transcription. BAY 11-7085 is an IκB-α inhibitor with IC50 value of <10μM for inhibiting the TNF-α-induced loss of IκB-α in HUVEC cells. Pre-treatment with BAY 11-7085 at concentration ranging in 1-20μM for 1h dose-dependently stabilized p-IκB-α and suppressed activation of NF-κB induced by TNF-α in HUVEC cells. Pre-treatment with 2.5-20μM BAY 11-7085 for 1h before 6-hour treatment with C pneumoniae could lead a concentration-dependent inhibition of C pneumoniae–induced ICAM-1 upregulation in human aortic endothelial cells. Combination of 5μM BAY 11-7085 with 200nM paclitaxel could attenuate the both basal and transient induction of IκBα phosphorylation by paclitaxel in Caov-3 cells, as well as decreased the viability of cells treated with paclitaxel. Administration of 5mg/kg BAY 11-7085 3 times weekly for 4 weeks could enhance paclitaxel (20 mg/kg, 3 times weekly)-induced inhibition of intraabdominal dissemination and production of ascites in athymic nude mice inoculated intraperitoneally with Caov-3 cells. |
