Intriguingly, global gene expression analysis revealed that K‐rasG12D expression resulted in activation of the JAK–STAT pathway (Figs. S3a and S3b).27 Encouraged by these data, we treated K and KP mice 1 week after tumor induction with ruxolitinib or vehicle control for a period of 10 weeks, euthanized them and analyzed their lungs. Here, SOAT1 is linked to neoplasm.
