Hypothesis

Does etoposide treatment lead to increased telomerase activity in pancreatic cancer cells?

Conclusion

Etoposide treatment increases telomerase activity in pancreatic cancer cells, which may contribute to drug resistance.

Supporting Evidence

  • Etoposide treatment resulted in two- to threefold increases in telomerase activity.
  • Telomerase activation was observed in multiple pancreatic cancer cell lines.
  • There was a negative correlation between telomerase activity and the percentage of dead cells after treatment.

Takeaway

When pancreatic cancer cells are treated with a drug called etoposide, they become better at avoiding death, and this is linked to an increase in a special enzyme called telomerase.

Methodology

MIA PaCa-2 cells were treated with etoposide at various concentrations, and telomerase activity was measured.
