Effects of tanshinone II A on the myocardial hypertrophy signal transduction system protein kinase B in rats
摘要
To study the effect of tanshinone II A on the cell signal transduction system protein kinase B (Akt) in rats with hypertrophy of the myocardium induced by partial constriction of the thoracic aorta. Rat models of myocardial hypertrophy were established by the thoracic aorta partial constriction method. Forty-eight rats were randomly divided into the sham-operative group
the model group
the valsartan treatment group
and the low-
medium-
and high-dose tanshinone treatment groups. The heart mass index (HMI)
left ventricular mass index (LVMI)
ejection fraction (EF)
left ventricular posterior wall (LVPW)
and interventricular septal thickness (IVS) were detected by high-frequency ultrasonography. The myocardial fiber diameter (MFD) was detected by HE staining
and the contents of p-Akt and p-Gsk3β in the myocardium were detected by Western blot. Compared with the sham-operative group
the levels of HMI
LVMI
LVPW
IVS
and MFD were increased respectively in the other groups (P<0.05); the contents of p-Akt and p-Gsk3β were also increased in the other groups. Compared with the model group
the levels of HMI
LVMI
LVPW
IVS
and MFD were decreased respectively in all treatment groups (P<0.05); the contents of p-Akt and p-Gsk3β were decreased in all treatment groups as well. There was no significant difference
however
among the low-
medium-
and high-dose tanshinone treatment groups and the valsartan treatment group (P>0.05). Tanshinone II A can prevent myocardial hypertrophy by its action on the protein kinase B (Akt) signaling pathway.
