Moreover, the production of reactive oxygen species (ROS) was significantly induced by GA. The activation of signal transducer and activator of transcription 3/janus kinase 2 (Stat3/JAK2) signaling pathway was inhibited by GA treatment. Intriguingly, blocking Stat3/JAK2 activation could further promote apoptosis and reduce cell viability induced by GA. However, GA-induced cell death was clearly abolished by ROS scavenger NAC, while the activation of Stat3/JAK2 signaling was restored by NAC. In vivo, GA showed effective role in reducing gastric tumor growth. Together, the findings here indicated that GA could be considered as an effective therapeutic candidate against human gastric cancer progression in future. Kinesin family protein 2A (KIF2A), an M-type nonmotile microtubule depolymerase, plays essential roles in development and progression of various human cancers. However, its exact function and the underlying mechanism in tumorigenesis of gastric cancer (GC) haven't been fully elucidated. In the present study, KIF2A was overexpressed in human GC and predicted poor prognosis according to the results of GEPIA analysis. KIF2A was also observed to be upregulated in 82 GC samples compared with paired pericarcinoma tissues. Its overexpression was associated with tumor metastasis (P = 0.047) and Ⅲ stage GC (P = 0.0267). The mRNA and protein expression levels of KIF2A were significantly suppressed in KIF2A specific siRNA transfected GC cells compared with the wild-type and negative control (NC) siRNA transfected cells. Furthermore, the effects of KIF2A on the growth, migration, invasion, and apoptosis of GC cell were evaluated in vitro and the underlying mechanisms were explored. It was found that silencing KIF2A effectively induced the apoptosis, and inhibited the proliferation, migration and invasion capacities of GC cells. Western b
