Hypothesis
p16 inhibits lymphangiogenesis.
Conclusion
Re-expressing p16 in pancreatic cancer cells significantly reduces tumor growth and prevents lymphatic metastasis.
Supporting Evidence
- Re-expression of p16 reduced primary tumor growth by 60%.
- Induction of p16 resulted in a 33% reduction in lymphatic vessel density.
- Only 1 out of 11 tumors with p16 expression had lymph node metastases.
Takeaway
When scientists turned on a gene called p16 in mice with pancreatic cancer, the tumors grew less and didn't spread to the lymph nodes as much.
Methodology
The study used an orthotopic mouse model of pancreatic cancer to examine the effects of inducible p16 expression on tumor growth, angiogenesis, and metastasis.
Limitations
Some tumors did not express p16 at the time of analysis, which may have affected the results.
Participant Demographics
Female NMRI nude mice were used in the study.
