Effects and Mechanisms of Saikosaponin D Improving the Sensitivity of Human Gastric Cancer Cells to Cisplatin.

ABSTRACT: Gastric cancer (GC) is the second leading cause of cancer deaths around the world. Chemoresistance is an important reason for poor prognosis of GC. Saikosaponin D (SSD) is a natural constituent from Radix Bupleuri and exhibits various activities including antitumors. This study investigated the effects and the mechanisms of SSD on cisplatin (cis-diamminedichloroplatinum, DDP) sensitivity of GC cells. Findings suggested that SSD could promote the inhibitory effect of DDP on proliferation and invasion and increase DDP-induced apoptosis in SGC-7901 and DDP-resistant cell line SGC-7901/DDP. We further identified that SSD increased levels of LC3 B and cleaved caspase 3 and decreased levels of p62, IKK β, p-IκB α, and NF-κB p65, suggesting that SSD might inhibit the IKK β/NF-κB pat
