OBJECTIVE: Kaempferol has been reported to play an anti-tumor role in various human cancers, while its role in gallbladder cancer (GBC) is unclear.

MATERIALS AND METHODS: We found that kaempferol significantly inhibited the growth, invasion and migration, meanwhile induced apoptosis through cells arrested at G0/G1 phase of GBC cell lines, including GBC-SD and SGC996 cells in vitro.

RESULTS: Kaempferol promoted the release of cytochrome C from the mitochondria to cytoplasm, the activation of c-caspase-3 and c-caspase-9 and increased the expression levels of pro-apoptotic factor Bax, meanwhile decreased the expression levels of anti-apoptotic factor Bcl-2. In addition, the expression levels of CDK4, CDK6 and cyclin D1, which are members of the CDK4/CDK6/cyclin D1 signaling pathway, were also decreased by kaempferol. Moreover, kaempferol could efficiently prevent tumor progression of GBC in the xenograft in vivo.

CONCLUSIONS: Our results demonstrated that kaempferol suppressed GBC progression through activation of the CDK4/CDK6/cyclin D1 signaling pathway, suggesting that it might be a potential anti-tumor agent for clinical treatment of GBC.
