Abstract | OBJECTIVES: METHODS: RESULTS: Compared to eNOS+/+ mice, we found that; 1) myocyte size was significantly increased in eNOS-/- mice; 2) cardiac expression of β-MHC was markedly elevated, while α-SKA levels remained unchanged in eNOS-/- mice; 3) cardiac total and interstitial CVF levels were significantly higher in eNOS-/- mice; and 4) cardiac TIMP-1 levels were significantly greater in eNOS-/- mice, however, cardiac TGF-β1 was not differently expressed between the two groups. CONCLUSION: The current study revealed that eNOS plays a beneficial role in cardiac remodeling, preventing the heart from development of myocyte hypertrophy and cardiac fibrosis. These findings support our previous report that eNOS may modify the severity of HCM phenotypes.
