Abstract:
Esophageal squamous cell carcinoma (ESCC) is one of the leading causes of cancer‐related death with poor prognosis in China. Identifying novel targeted therapies in ESCC is urgently needed. The aberrant activation of NF‐κB signalling pathway is critical for prognosis and recurrence of ESCC, which make it a potential target in the treatment of ESCC. Here, we found that pristimerin inhibited ESCC cell proliferation, migration, invasion, induced cell apoptosis, and eliminated cancer stem‐like cells (CSCs). It also showed a synergistic effect on ESCC when combined with 5‐fluorouracil (5‐FU). Moreover, pristimerin potently inhibited the growth of ESCC xenograft in nude mice. The anti‐ESCC effects of pristimerin were demonstrated to be associated with the inhibition of NF‐κB pathway by suppressing tumour necrosis factor α (TNFα)‐induced IκBα phosphorylation, p65 translocation, and NF‐κB‐dependent gene expression. This study provides an evidence for the development of pristimerin to be a new therapeutic agent for ESCC. Significance of the study Although several approaches including surgery, chemotherapy, and radiotherapy had been applied in the treatment of ESCC, more effective targeted chemotherapies are required to increase the survival rates of patients. This study suggested that inhibiting NF‐κB signalling pathway could be an effective approach for the treatment of ESCC. Pristimerin, a potent NF‐κB inhibitor, exerted potent anti‐ESCC effects both in vitro and in vivo , which may be a promising therapeutic agent for ESCC.
