Metformin induces ACC inactivation in primary hepatocytes. 2019-05-10 · Background Atrial lipid metabolic remodeling is critical for the process of atrial fibrillation (AF). Abnormal Fatty acid (FA) metabolism in cardiomyocytes is involved in the pathogenesis of AF. MET (Metformin), an AMPK (AMP-activated protein kinase) activator, has been found to be associated with a decreased risk of AF in patients with type 2 diabetes. However, the specific mechanism remains Metformin Activates the AMPK-mTOR Pathway by Modulating lncRNA TUG1 to Induce Autophagy and Inhibit Atherosclerosis Ganhua You,1,2 Xiangshu Long,3,4 Fang Song,3,4 Jing Huang,3,4 Maobo Tian,3,4 Yan Xiao,3,4 Shiyan Deng,3,4 Qiang Wu3,4 1Guizhou University School of Medicine, Guiyang 550025, People’s Republic of China; 2Guizhou Institute for Food and Drug Control, Guiyang 550004, People’s Metformin acts on your mitochondria, the power plants of your cells, as well as AMPK, an enzyme that tells your cells when they should take in sugar from your bloodstream for energy. [5] People have also used metformin for off-label purposes like treating PCOS, to reduce risk of heart disease, [6] [7] and to prevent cancer. Long-term administration of metformin may attenuate cardiac hypertrophy induced by pressure overload in nondiabetic mice, and this attenuation is highly dependent on AMPK activation. Taken together, these results indicated that metformin is able to protect neuronal cells from oxidative injury, at least in part, via the activation of AMPK.

After giving mice metformin, an AMPK activator, we were able to reduce nicotine withdrawal, and found that this was dependent on the presence of the AMPK protein in the hippocampus. This study suggests that AMPK activation could be a target for smoking cessation. AMPK plays a very significant role in the control of blood sugar, and low AMPK levels have been implicated in diabetes.

Taken together, these results indicated that metformin is able to protect neuronal cells from oxidative injury, at least in part, via the activation of AMPK. As metformin is comparatively cheaper with much less side effects in clinic, our findings support its potential to be a drug for prevention and treatment of aging and aging‐related diseases.

3-Methyladenine (3-MA) partly abolished this effect. Metformin treatment and mCherry-GFP-LC3B plasmid transfection showed that metformin could induce the autophagic flux. 3-Methyladenine (3-MA) partly abolished this effect.

The activation of AMPK by metformin could be consequent to Complex 1 inhibition and raised AMP through the canonical adenine nucleotide pathway or alternatively by activation of the lysosomal AMPK pool by other mechanisms involving the aldolase substrate fructose 1,6-bisphosphate or perturbations in the lysosomal membrane.
