By analyzing tumor sequence data to infer gene-specific and patient-specific mutation rates, we used (for the first time) some straightforward mathematics of mutation rates to project the delay of resistance obtained by suppression of APOBEC mutation 🧪.

—ALK resistance mutations show greater APOBEC attribution than e.g. EGFR mutations. Therefore, patients with ALK+ tumors would benefit more from therapies suppressing APOBEC activity 🧪.

APOBEC drives genetic variation in lung tumors, especially in response to tyrosine kinase inhibitor therapy 🧪. Inhibition of APOBEC during use of tyrosine kinase inhibitors could improve outcomes. In a paper just out in Lung Cancer, we show how much.
