| 1 | Glucagon-like peptide-1 attenuates cardiac hypertrophy via the AngII/AT1R/ACE2 and AMPK/mTOR/p70S6K pathways显示文摘Glucagon-like peptide-1(GLP-1),a novel type of glucose-lowering agent,has been reported to exert cardioprotective effects.However,the cardioprotective mechanism of GLP-1 on spontaneous hypertension-induced cardiac hypertrophy has not been fully elucidated.In this study,we revealed that liraglutide or alogliptin treatment ameliorated spontaneous hypertension-induced cardiac hypertrophy,as evidenced by decreased levels of cardiac hypertrophic markers(atrial natriuretic peptide,brain natriuretic peptide,andβ-myosin heavy chain),as well as systolic blood pressure,diastolic blood pressure,mean arterial pressure,and histological changes.Both drugs significantly reduced the levels of angiotensin II(AngII)and AngII type 1 receptor(AT1R)and upregulated the levels of AngII type 2 receptor(AT2R)and angiotensin-converting enzyme 2(ACE2),as indicated by a reduced AT1R/AT2R ratio.Simultaneously,treatment with liraglutide or alogliptin significantly increased GLP-1 receptor expression and adenosine monophosphate-activated protein kinase(AMPK)phosphorylation and downregulated the phosphorylation of mammalian target of rapamycin(mTOR),p70 ribosomal S6 protein kinase,and eukaryotic translation initiation factor 4E binding protein 1 in spontaneous hypertension rats.Furthermore,our data demonstrated that the AMPK inhibitor compound C or mTOR activator MHY1485 inhibited the anti-hypertrophic effect of GLP-1.In summary,our study suggests that liraglutide or alogliptin protects the heart against cardiac hypertrophy by regulating the expression of AngII/AT1R/ACE2 and activating the AMPK/mTOR pathway,and GLP-1 agonist can be used in the treatment of patients with cardiac hypertrophy. | Jing Wang Shaohua Fan Qianfeng Xiong Yu Niu Xin Zhang Junnan Qin Yawei Shi Lihui Zhang | 2021 | Acta Biochimica et Biophysica Sinica2021，53，9： | 1 |
