Representative image of western blotting (A) and protein levels of β-1 adrenergic receptor (β1-AR, B) in cultured neonatal rat cardiomyocytes exposed for 120 min to Isoproterenol (ISO, 10 µM); Isoproterenol (10 µM) + Matrix metalloproteinase inhibitor (MMPi-GM6001, 10 µM) and Isoproterenol (10 µM) + Eicosapentaenoic acid (EPA, 3.3 µM). C—control cells without ISO. Results were normalized to glyceraldehyde-3-phosphate dehydrogenase protein level (GAPDH). Data are presented as means ± SEM.
