NF‐κB
and enhances the therapeutic efficacy of pembrolizumab
Drug Development Research(2021)
摘要
Papillary thyroid carcinoma (PTC) is the most common pathological type of thyroid cancer. Studies have shown that platycodin D has several pharmacological effects like anti-inflammatory, immunomodulatory, and anti-tumor effects, while the effect and mechanism of platycodin D on PTC are still unclear. This study was designed to investigate the effects of platycodin D on PTC by a series of in vitro and in vivo experiments. The results revealed that platycodin D inhibits PTC cell viability and clonal levels and affects PTC cell cycle. Platycodin D promotes apoptosis in PTC cells. Furthermore, it inhibits the activation of NF-κB signaling pathway and affects cell growth. Platycodin D inhibits PD-L1 expression and enhances the effect of pembrolizumab on PTC cells. In conclusion, platycodin D can effectively block the progression of PTC through the NF-κB signaling pathway, accompanied by cell cycle arrest and enhanced cell apoptosis. In vitro and in vivo, platycodin D was shown to enhance pembrolizumab's sensitivity to PTC. Platycodin D is a promising monomer for therapy of PTC, providing references for future research on PTC treatment.
