European journal of pharmacology.Eur J Pharmacol.2017 Jan 10. pii: S0014-2999(17)30003-1. doi: 10.1016/j.ejphar.2017.01.003. [Epub ahead of print]
The aim of this study was to examine whether metformin, a biguanide anti-hyperglycemic drug, dilates retinal blood vessels in rats. Ocular fundus images were captured with an original high-resolution digital fundus camera in vivo and diameters of retinal blood vessels were measured. Both systemic bl

The retina is considered to be the most metabolically active tissue in the body. However, the link between energy metabolism and retinal inflammation, as incited by microbial infection such as endophthalmitis, remains unexplored. In this study, using a mouse model of Staphylococcus aureus (SA) endop

The rate of hippocampal neurogenesis declines with aging. This is partly explained by decreased neural responsiveness to various cues stimulating metabolism. AMP-activated protein kinase (AMPK), a pivotal enzyme regulating energy homeostasis in response to metabolic demands, showed the diminished se

AMPK Activation Stimulates Myofibrillar Protein Degradation and Expression of Atrophy-Related Ubiquitin Ligases by Increasing FOXO Transcription Factors in C2C12 Myotubes

NAKASHIMA Kazuki,YAKABE Yoko
Bioscience, biotechnology, and biochemistry 71(7), 1650-1656, 2007-07-23
… The present study was designed to examine the effect of 5-aminoimidazole-4-carboxamide-1-β-D-ribonucleoside (AICAR)-induced AMPK signaling on effector mechanisms of myofibrillar protein degradation and the expression of atrophy-related genes (atrogin-1/MAFbx, MuRF1, proteasome C2 subunit, calpains, cathepsin B, and caspase-3) in C2C12 myotubes. …
