🚀New preprint w/ @roberto_amv: We used chemogenetics to precisely control mitochondrial H2O2 in skeletal muscle in vivo. This exposes a dose-dependent sequence: translation suppression → proteolysis → denervation-like → degeneration @tejensen23 www.biorxiv.org/content/10.1...

Check out our latest paper challenging the long-standing belief that insulin elicits a transient H₂O₂ production. New insights into skeletal muscle redox signaling and insulin action 🤩
Our new paper in Redox Biol showing that insulin stimulation of skeletal muscle surprisingly does not detectably increase the ROS H2O2 using state-of-art methods in different models including humans, but in fact causes a selective reductive shift - enjoy www.sciencedirect.com/science/arti...

Free radicals and antioxidants: appealing to magic Our short paper argues that molecules cannot be classified as good or evil. Limited evidence supporting the consumption of antioxidants or superfoods and such interventions risk disrupting fundamental redox processes. www.cell.com/trends/endoc...
Free radicals and antioxidants: appealing to magic
In biology, there are no good or evil molecules. There is limited or no evidence to support the consumption of antioxidants or (super)foods rich in antioxidants, for the intended purpose of an antioxi...
