Abstract
Gastric cancer (GC) is a very common type of cancer. Although current treatment modalities include surgical resection and chemotherapy, many patients are either not eligible for radical resection or have a poor response to chemotherapy. Due to the complex features of the disease, there is a need for complementary therapy. In the present study, the effects of oridonin on cell proliferation, invasion and apoptosis were assessed in the HGC-27 cell line using the Cell Counting Kit-8 assay, real-time cell analysis, and an Annexin V-FITC/propidium iodide (PI) detection kit, respectively. The effect of oridonin on apoptosis, through the JNK pathway, was also investigated using western blotting. The present study demonstrated that oridonin can suppress cell viability and inhibit cell proliferation by inducing G2/M arrest. Oridonin also induced caspase-dependent apoptosis in cells by activating the phosphorylated-JNK/C-JUN pathway. These results demonstrate the potential of oridonin as a potential therapeutic compound for the treatment of GC.
