To evaluate the cytotoxic and antimetastatic effects of β-lapachone on mammary tumor spheroids (MTS) and its potential implications for breast cancer treatment.
Key Findings:
β-lapachone induced significant cell death in MCF-7 spheroids, suggesting its potential as a therapeutic agent.
Cell viability decreased with increasing concentrations of β-lapachone, indicating a dose-dependent effect.
Migration of cells from spheroids was suppressed by β-lapachone treatment, highlighting its antimetastatic properties.
β-lapachone restored E-cadherin expression and downregulated vimentin, indicating modulation of epithelial–mesenchymal transition (EMT) and its implications for cancer progression.
Interpretation:
The findings suggest that β-lapachone has potential as an antitumor agent by reducing cell viability and migration while affecting EMT markers in breast cancer models, warranting further investigation into its clinical applications.
Limitations:
The study was conducted in vitro, which may not fully replicate in vivo conditions; future studies should include in vivo models.
Only one breast cancer cell line (MCF-7) was used, limiting the generalizability of the results; additional cell lines should be tested.
Conclusion:
β-lapachone shows promise as a therapeutic agent against breast cancer by inhibiting cell viability and migration, warranting further investigation in clinical settings to explore its full potential.
