Case study – Gene expression profiling to understand and combat drug resistance

RNA sequencing provides insight into the mechanism of kinase inhibitor resistance

Clinical response to targeted therapies is almost always temporary as cancers develop resistance.

In our new case study we show that RNA sequencing provides valuable insight into cellular alterations upon the development of resistance. Furthermore, it can aid in finding alternative treatment options once resistance has occurred. This is shown for cell lines resistant to the pan-FGFR kinase inhibitor erdafitinib. We could confirm that targeting of an upregulated gene with small molecule inhibitors led to cellular response, indicating that this pathway was important in the resistance development.
