Abstract:

Objective

To investigate the effect of costunolide (Cos) on the proliferation and invasion of gallbladder cancer cells and its possible mechanism.

Methods

Gallbladder cancer cells were treated with different concentrations of Cos. Cell proliferation, apoptosis, cycle, migration, and changes of related proteins expression were detected with CCK-8, clone formation, flow cytometry, Transwell and Western blot.

Results

The result of CCK-8 showed that the cytoactive in Cos-treated group was inhibited to varying degree and the inhibition was time and dose-dependent. Clone formation experiment showed that the cell clone number in Cos group was significantly less than that in control group with dose-dependent relation. The results of flow cytometry showed that the percentage of apoptosis and proportion of cells in S andG2/M phases increased in Cos group. Western blot test results showed that, as Cos concentration increased, the expression of cyclin A, cyclin B1 decreased gradually, and the expression of p-JNK, apoptosis-related proteins such as cleaved PARP, cleaved caspase-3, cleaved caspase-9, Bax, etc. increased, while the expression of Bcl-2 decreased. Transwell results showed that the number of transmembrane cells decreased with the increase of Cos concentration. Western blot test results showed that, the expression of MMP-2, MMP-9 decreased with the increase of Cos concentration.

Conclusions

Cos can inhibit the proliferation of gallbladder cancer cells, induce cell apoptosis, block cell cycle, and inhibit cell migration in vitro.
