    ABSTRACT: In animal models of clinical entities causative of severe right and left ventricular (LV) pressure overload hypertrophy, increased density of the cellular microtubule network, through viscous loading of active myofilaments, causes contractile dysfunction that is normalized by microtubule depolymerization. In this study, 86 male mice were divided into seven groups. The transverse ascending aorta constriction (TAC) in six groups were performed in order to make heart failure model. Mice in each group were injected with G-CSF or/and telmisartan subcutaneously at different time respectively. Results showed that reduction in left ventricular volume and improved function persisted at 2 week, but recurrent dilatation at 4 weeks was associated with a loss of functional improvement. Compared with PBS group, the expression of VEGF protein and HIF-1 mRNA were significantly higher in mice injected with G-CSF or/and telmisartan (P<0.05). The expression of p53 mRNA, myocardial fibrosis and mortality were significantly lower in mice injected with G-CSF or/and telmisartan (P<0.05). It could be concluded that G-CSF can delay the progression of pressure overload induced ventricular reconstruction and heart failure in mice.
