BPH-175-1217-s001.pdf (1.4M) GUID:?56718445-5035-4261-A2D5-3571C9AD5F67 Abstract Background and Purpose Metformin, a small molecule, antihyperglycaemic agent, is a well\known activator of AMP\activated protein kinase (AMPK) and protects against cardiac fibrosis. CHIR-99021 tyrosianse inhibitor However, the underlying mechanisms remain elusive. TGF1 is definitely a key cytokine mediating cardiac fibrosis. Here, we investigated the effects of metformin on TGF1 production induced by angiotensin II (AngII) and the underlying mechanisms. Experimental Approach Wild\type and AMPK2?/? C57BL/6 mice were injected s.c. with metformin or saline and infused with AngII (3?mgkg?1day?1) for 7?days. Adult mouse cardiac fibroblasts (CFs) were isolated for experiments. Key Results In CFs, metformin inhibited AngII\induced TGF1 manifestation via AMPK activation. Analysis using.
