Hypothesis

Does RNA interference against XIAP increase the sensitivity of canine tumor cell-lines to TRAIL and doxorubicin?

Conclusion

XIAP directed siRNA's significantly enhance the sensitivity of canine tumor cell-lines to TRAIL and doxorubicin.

Supporting Evidence

  • All XIAP siRNA treated cell-lines showed over 80% mRNA down-regulation.
  • BDE cells showed a 14-fold increase in sensitivity to TRAIL after XIAP depletion.
  • Doxorubicin treatment increased sensitivity in BDE cells by more than eight-fold.

Takeaway

Scientists found a way to make cancer cells in dogs more sensitive to treatments by using a special technique that reduces a protein that protects the cells from dying.

Methodology

The study used small interfering RNA (siRNA) to target XIAP in three canine tumor cell-lines and measured cell viability after treatment with TRAIL and doxorubicin.

Limitations

The study was conducted in vitro, and the results may not directly translate to in vivo applications.

Participant Demographics

Canine tumor cell-lines derived from bile-duct epithelia, mammary carcinoma, and osteosarcoma.
