Hypothesis
The study investigates the role of NF-κB activity in thymidylate synthase inhibitor-resistant tumor cells.
Conclusion
The study found that high nuclear NF-κB activity and overexpression of NF-κB protein and mRNA are intrinsic characteristics of thymidylate synthase inhibitor-resistant cell lines.
Supporting Evidence
- High NF-κB activity was observed in drug-resistant cell lines compared to sensitive ones.
- NF-κB p50 and p65 proteins were overexpressed in resistant cell lines.
- No gene amplification of NF-κB was detected in drug-resistant cell lines.
Takeaway
Some cancer cells can resist treatment because they have a lot of a protein called NF-κB, which helps them survive even when drugs are trying to kill them.
Methodology
The study tested NF-κB activity, protein, and mRNA expression levels in five pairs of thymidylate synthase inhibitor-resistant and sensitive cell lines.
