| Title |
Inhibiting tankyrases sensitizes KRAS mutant cancer cells to MEK inhibitors by FGFR2 feedback signaling |
| Organism |
Homo sapiens |
| Experiment type |
Expression profiling by array

| Summary |
Tankyrases (TNKS) play roles in Wnt signaling, telomere homeostasis and mitosis, offering attractive targets for anti-cancer treatment. Using unbiased combination screening in a large panel of cancer cell lines, we have identified a strong synergy between TNKS and MEK inhibitors in KRAS mutant cancer cells. Our study uncovers a novel function of TNKS in the relief of a feedback loop induced by MEK inhibition on FGFR2 signaling pathway. Moreover, dual inhibition of TNKS and MEK leads to more robust apoptosis and anti-tumor activity both in vitro and in vivo than effects observed by previously reported MEK inhibitor combinations. Altogether, our results show how a novel combination of TNKS and MEK inhibitors can be highly effective in targeting KRAS mutant cancers by suppressing a newly discovered resistance mechanism.
This experiment is designed to detect genes differentially expressed in the combination treatment compared to others

| Overall design |
SW480 cells were seeded in 10cm dishes and treated for 4h and 16h with DMSO, TNKS inhibitor (TNKSi : NVP-TNKS656), MEK inhibitor (MEKi : AZD6244) or the combination of both at 1uM final
