Abstract

Kangfuxin (KFX) is an oral liquid derived from Periplaneta americana, with complex components. KFX has been demonstrated to exhibit anticancer activity in a variety of different types of tumor, including gastric cancer; however, its underlying molecular mechanism remains unclear. The present study was designed to investigate the pro‑apoptotic effects of KFX on SGC‑7901 cells, in order to provide a theoretical basis for clinical application. In order to clarify the pro‑apoptotic effects of KFX on SGC‑7901 cells, MTT analysis was conducted. To evaluate the anticancer effect of KFX, peroxisome proliferator‑activated receptor (PPAR)‑γ was analyzed by reverse transcription‑polymerase chain reaction. Western blot analysis was used to determine the effects of KFX on the expression of cleaved caspase‑3, phosphorylated extracellular signal‑regulated kinase (p‑ERK), ERK, tumor protein p53 (p53), B‑cell lymphoma 2 (Bcl‑2), Bcl‑2 associated X, interleukin (IL)‑6 and IL‑1β. In addition, terminal deoxynucleotidyl‑transferase‑mediated dUTP nick‑end labeling (TUNEL) analysis was used to detect apoptosis in SGC‑7901 cells. It was revealed that PPAR‑γ was increased in SGC‑7901 cells following treatment with KFX, shown by an increase in mRNA expression. Furthermore, western blot analysis identified that KFX treatment groups exhibited markedly inhibited levels of Bcl‑2, IL‑6, IL‑1β and p‑ERK, and induced p53 protein expression. Additionally, TUNEL and MTT assays demonstrated that treatment with KFX may induce SGC‑7901 cell apoptosis and inhibit proliferation. In conclusion, to the best of our knowledge, the results of the present study demonstrated for the first time that KFX may induce SGC‑7901 cell apoptosis and inhibit its proliferation, and this may be primarily attributed to its role in mitogen‑activated protein kinase/extracellular‑signal‑regulated kinase kinase/ERK signaling pathway inhibition.
