CFL1 and capillary hemangioma: We have previously shown that propranolol treatment of infantile hemangioma endothelial cells decreased phosphorylation of the actin regulatory protein cofilin [26], however Western blot analysis of SVR cells showed no change in the phosphorylation of cofilin, ezrin/radixin/moesin (ERM), or myosin phosphatase targeting subunit (MYPT) in reponse to propranolol (Figure 6C).
