Hypothesis
The study investigates the effect of selective and non-selective cyclo-oxygenase inhibition on tumor growth and metastasis in breast cancer.
Conclusion
Cyclo-oxygenase inhibitors significantly reduce tumor growth and metastasis in breast cancer models.
Supporting Evidence
- Both SC-236 and indomethacin significantly reduced primary tumor weight and the number of lung metastases.
- Microvessel density was reduced and tumor cell apoptosis increased in treated mice.
- VEGF production was decreased in vitro with cyclo-oxygenase inhibition.
Takeaway
This study shows that certain medications can help shrink breast tumors and stop them from spreading.
Methodology
The study used an orthotopic model of breast cancer in mice, injecting tumor cells and treating with COX inhibitors.
Limitations
The study was conducted in a mouse model, which may not fully replicate human breast cancer.
Participant Demographics
Female BALB/c mice, aged 10-12 weeks.
