Hypothesis
Thalidomide influences melanoma tumor growth and blood supply patterns.
Conclusion
Thalidomide inhibits the formation of vasculogenic mimicry channels and mosaic vessels in melanoma, potentially through the NF-κB signaling pathway.
Supporting Evidence
- Thalidomide significantly decreased tumor volume compared to the control group.
- The number of vasculogenic mimicry channels and mosaic vessels was lower in the treatment group.
- VEGF, NF-κB, PCNA, MMP-2, and MMP-9 expression were significantly reduced in the treatment group.
Takeaway
Thalidomide helps slow down the growth of melanoma tumors and reduces their blood supply, which is important for the tumors to grow.
Methodology
Thirty C57 mice were divided into treatment and control groups, with thalidomide administered daily, and tumor sizes measured until sacrifice.
Participant Demographics
C57BL/6 mice, 6-8 weeks old.
