Hypothesis

Does apigenin inhibit proteasome activity in breast cancer cells and xenografts?

Conclusion

Apigenin effectively inhibits proteasome activity and induces apoptosis in breast cancer cells and tumors.

Supporting Evidence

  • Apigenin inhibited cell viability in a dose-dependent manner.
  • Caspase-3/caspase-7 activation indicated apoptosis in treated cells.
  • No apparent toxicity was observed in treated mice.

Takeaway

Apigenin, a natural compound found in fruits and vegetables, can help stop breast cancer cells from growing and make them die.

Methodology

MDA-MB-231 breast cancer cells and xenografts were treated with apigenin, followed by assays to measure cell viability, proteasome activity, and apoptosis.

Limitations

The study used high concentrations of apigenin that may not reflect typical dietary intake.

Participant Demographics

Female athymic nude mice were used for in vivo experiments.
