Hypothesis
Can deoxyribonuclease I (DNase I) treatment prevent blood-borne liver metastasis of transplanted tumor cells in mice?
Conclusion
DNase I treatment significantly inhibits liver metastasis and prolongs survival in mice with transplanted tumors.
Supporting Evidence
- DNase I treatment reduced liver weight significantly compared to control.
- All control mice died within 18 days, while DNase I treatment extended survival to 24 days.
- Histological analysis showed fewer metastatic foci in DNase I-treated mice.
Takeaway
Researchers found that a special treatment called DNase I can help stop cancer cells from spreading to the liver in mice, making them live longer.
Methodology
Mice were injected with tumor cells and treated with DNase I or a-chymotrypsin, followed by measuring liver weight and survival rates.
Limitations
The study used a mouse model, which may not fully replicate human cancer metastasis.
Participant Demographics
Female BALB/c x DBA/2 mice, 6 to 8 weeks old.
