Bispecific antibody suppresses osteosarcoma aggressiveness through regulation of NF-κB signaling pathway

Osteosarcoma is one of the most lethal malignancies, and the prognosis remains dismal due to the paucity of effective therapeutic targets. Bmi-1 and TRIM-14 are associated with the initiation and progression of osteosarcoma, which could promote angiogenesis, invasion, and apoptotic resistance in bon...

description Osteosarcoma is one of the most lethal malignancies, and the prognosis remains dismal due to the paucity of effective therapeutic targets. Bmi-1 and TRIM-14 are associated with the initiation and progression of osteosarcoma, which could promote angiogenesis, invasion, and apoptotic resistance in bone cancer tissue. In this study, we constructed a bispecific antibody of BsAbBmi/TRIM targeting Bmi-1 and TRIM-14 and investigated the therapeutic value in bone carcinoma cells and xenograft mice. Our results showed that Bmi-1 and TRIM-14 expression levels were markedly upregulated correlated with nuclear factor-κB nuclear translocation in bone cancer cells and clinical carcinoma tissues. Results have demonstrated that overexpression of Bmi-1 and TRIM-14 promoted growth, proliferation, aggressiveness, and apoptosis resistance of osteosarcoma cells. BsAbBmi/TRIM administration significantly inhibited nuclear factor-κB expression derived by matrix metalloproteinase–9 promoter. BsAbBmi/TRIM administration inhibited growth of osteosarcoma cells and downregulated Bmi-1 and TRIM-14 expression levels. Data also demonstrated that migration and invasion of osteosarcoma cells were also inhibited by BsAbBmi/TRIM. In addition, results illustrated that BsAbBmi/TRIM inhibited tumor growth and tumorigenicity by blockaded sensor expression in nuclear factor-κB signal pathway. Furthermore, in vivo study showed that BsAbBmi/TRIM treatment markedly inhibited the tumorigenicity and growth of osteosarcoma cells compared to either AbBmi-1 or AbTRIM-14 treatment. Notably, survival of xenograft mice was prolonged by BsAbBmi/TRIM treatment compared to either AbBmi-1 or AbTRIM-14 treatment. In conclusion, these results provided new evidence that BsAbBmi/TRIM inhibited the progression of osteosarcoma, which suggest that BsAbBmi/TRIM may be a novel anti-cancer agent for osteosarcoma therapy.
