The ROS1 Mutation: A Target for a Small Population with Apparent Sensitivity to XALKORI

Article

After the last several posts have discussed our friend and lung cancer expert Dr. Ross Camidge, we'll turn to the related topic of ROS mutations, which have been the subject of research by Dr. Ross Camidge (though apparently not named for him) and also researchers at Massachusetts General Hospital. This is a gene for a DNA repair protein, and the tyrosine kinase binding portion (the part that gets turned on to set off a cascade of downstream intracellular events) for ROS1 is very similar to that for ALK.
