Abstract:
Objective To explore the contribution of endoplasmic reticulum stress to cardiac myocyte apoptosis in mouse congestive heart failure induced by Doxorubicin.Methods Doxorubicin (DOX)was administered intraperitoneally to rats,2 mg/kg doses over 8 weeks.Echocardiographic and hemodynamics measurements were obtained at 8 weeks after treatment.Then left ventricular (LV) samples were collected.The successfully established rats were divided into 3 groups (Fu Shen Ke Li 40 mg/kg,60 mg/kg,and 80 mg/kg).After 5 weeks post the operation,an echocardiographic was performed on all the rats under narcotism,Western blot to test the B-cell lymphoma-2 (Bcl-2),myeloid cell leukemia-1 (Mcl-1),Bcl-2-Associated X (Bax),Caspase-3,C/EBP homologous protein (CHOP),and 78-kDa glucose-regulated protein(GRP78),and reverse transcription-polymerase chain reaction (RT-PCR) to test the mRNA expression levels of Mcl-1,and NOXA.Results The left ventricular end-diastolic diameter (LVEDD),left ventricular end systolic diameter (LVESD),left ventricular ejection fraction (LVEF) prompted modeling success The left ventricular end-diastolic diameter (LVEDD),left ventricular ejection fraction (LVEF),and fractional shortening (FS) have been improved in high and middle groups of Fu Shen Ke Li.Compared to the model group,higher expression levels of Bcl-2,and Mcl-1 were,lower expressions of Bax,NOXA,CHOP,and GRP78 were (P ＜ O.05) in 3 groups of Fu Shen Ke Li.Compared to the model group,there were higher mRNA expression level of Mcl-1 was,lower mRNA expression of NOXA was (P ＜ 0.05) in 3 groups of Fu Shen Ke Li.Conclusions Fu Shen Ke Li depresses endoplasmic reticulum stress,which can reduce the apoptosis of myocardial cells,and ultimately achieve the purpose of treatment of heart failure.
