ROS1 and neoplasm: The lack of change in most of the EMT and dormancy markers upon the addition of TGFβ, or low levels of EMMPRIN in the CT26-WT cells, may suggest that additional factors (e.g., FGFs, IGF, ROS, S100A8/9 [56]) that are lacking when only recombinant proteins are added may be needed to enhance the production of the EMT and dormancy markers in the CT26-WT tumor cells.
