To investigate the effects of evodiamine (Evo)
a component of Evodiaminedia rutaecarpa (Juss.) Benth
on cardiomyocyte hypertrophy induced by angiotensin II (Ang II) and further explore the potential mechanisms. Cardiomyocytes from neonatal Sprague Dawley rats were isolated and characterized
and then the cadiomyocyte cultures were randomly divided into control
model (Ang II 0.1 μmol/L)
and Evo (0.03
0.3
3 μmol/L) groups. The cardiomyocyte surface area
protein level
intracellular free calcium ([Ca2+]i) concentration
activity of nitric oxide synthase (NOS) and content of nitric oxide (NO) were measured
respectively. The mRNA expressions of atrial natriuretic factor (ANF)
calcineurin (CaN)
extracellular signal-regulated kinase-2 (ERK-2)
and endothelial nitric oxide synthase (eNOS) of cardiomyocytes were analyzed by real-time reverse transcriptionpolymerase chain reaction. The protein expressions of calcineurin catalytic subunit (CnA) and mitogen-activated protein kinase phosphatase-1 (MKP-1) were detected by Western blot analysis. Compared with the control group
Ang II induced cardiomyocytes hypertrophy
as evidenced by increased cardiomyocyte surface area
protein content
and ANF mRNA expression; increased intracellular free calcium ([Ca2+]i) concentration and expressions of CaN mRNA
CnA protein
and ERK-2 mRNA
but decreased MKP-1 protein expression (P<0.05 or P<0.01). Compared with Ang II
Evo (0.3
3 μmol/L) significantly attenuated Ang II-induced cardiomyocyte hypertrophy
decreased the [Ca2+]i concentration and expressions of CaN mRNA
CnA protein
and ERK-2 mRNA
but increased MKP-1 protein expression (P<0.05 or P<0.01). Most interestingly
Evo increased the NOS activity and NO production
and upregulated the eNOS mRNA expression (P<0.05). Evo signifificantly attenuated Ang II-induced cardiomyocyte hypertrophy
and this effect was partly due to promotion of NO production
reduction of [Ca2+]i concentration
and inhibition of CaN and ERK-2 signal transduction pathways.
