Metastatic edits to FAK

Drugs that inhibit cell migration pathways, such as that mediated by the kinase FAK, may prevent metastasis and improve long-term survival in cancer patients. Amin et al. found that the RNA-editing enzyme ADAR supports the activity of FAK. In lung adenocarcinoma cells, ADAR bound to and edited FAK mRNA in a manner that improved its stability, thus increasing the abundance of FAK protein and enhancing the migration of these cells. High ADAR expression was a poor prognostic indicator in patients. These findings suggest that inhibiting FAK may be therapeutic in patients with ADAR-positive lung adenocarcinoma.
