主　　题：Multiple myeloma NF-κB JaponiconeA bortezomib drug resistance 

摘      要：Objective:Multiple myeloma(MM)remains incurable with high rates of *** therapeutic drugs are therefore urgently needed to improve the ***(JA),a natural product isolated from Inula japonica Thunb,has shown good anti-MM potential.A comprehensive study should therefore be conducted to identify both the in vitro and in vivo mechanisms of the anti-MM effects of ***:CCK8 assays and flow cytometry were used to detect the proliferation,apoptosis,and cell cycle of MM cell lines when treated with *** vivo experiments were conducted using subcutaneous xenograft mouse *** also identified possible targets and the mechanism of JA using RNA-seq and c-Map databases,and identified the specific targets of JA in bortezomib-sensitive and-resistant MM cell lines using CETSA,DARTS,and rescue ***,JA and bortezomib were used separately or together to characterize their possible synergistic ***:In vitro,JA inhibited proliferation,and induced apoptosis and G2/M phase arrest in MM cell lines,and selectively killed primary CD138+MM *** vivo,JA also demonstrated a strong anti-tumor effect with no observable *** addition,JA showed synergetic effects in combination with bortezomib,and enhanced the anti-tumor effect of bortezomib in bortezomibresistant *** and DARTS confirmed direct binding of JA to NF-κB inhibitor kinase beta(IKKβ),and overexpression of IKKβor knockdown of IκBαpartially rescued the apoptosis induced by ***:JA exhibited strong anti-tumor effects in *** sensitized myeloma cells to bortezomib and overcame NF-κB-induced drug resistance by inhibiting IKKβ,providing a new treatment strategy for MM patients.
