Hypothesis
Does the knockout of the MIF gene affect the development and progression of bladder cancer in mice?
Conclusion
MIF knockout mice developed less aggressive bladder tumors compared to wild type mice, suggesting MIF plays a role in cancer progression.
Supporting Evidence
- MIF knockout mice developed only T1 disease, while wild type mice developed T2 disease.
- MIF mRNA levels were three-fold higher in BBN treated animals with invasive cancer.
- PECAM-1 staining showed significantly more stromal vessels in tumors of wild type animals compared to knockout animals.
Takeaway
Mice without the MIF gene had less severe bladder cancer than those with it, showing that MIF might help cancer grow.
Methodology
Mice were treated with a carcinogen and evaluated for tumor development and characteristics over 23 weeks.
Limitations
The study was based on a small pilot group and needs further validation in larger studies.
