Vascular effects of imatinib and ET-1 in pulmonary veins of GPs. a Concentration-response curve of imatinib in naïve PVs: (□) PV (n = 5). b Treatment of naïve PVs with 1 nM ET-1 to obtain a stable pre-constriction: (■) PV 1 nM ET-1 (n = 6). The dashed line indicates the end of pre-treatment. c Effect of imatinib in ET-1-pre-constricted PVs: (■) PV (n = 9)
