Science Round-Up Seconds: PGC-1 Alpha 4 Unlocks Muscle Growth, Alpha Lipoic Acid & Dietary N-6 Overload, Aspirin & Other NSAIDs Your Liver & Overall Mortality
Myotubes under the microscope - vehicle (top, normal size), clenbuterol (+100% protein content, middle), clenbuterol + PGC1a4 inhibition (+50% protein content, bottom) Actually I would hope that you have by now already listened to yesterday's installment of the SuppVersity Science Round-Up . If you did, you are one of a group of highly privileged trainees who already knows why not all PGC1-alpha is created equal and how the alpha-4 isoform does appear to be the missing link between myostatin, on the one hand, and IGF-1 on the other. If you have already listened to the show, you may also have noticed that I was pretty excited about the publication of the Ruas paper (Ruas. 2012). Firstly this study has almost everything you could expect from cutting edge science: A in-vitro tudy to elucidate the basic mechanisms, an in-vivo rodent study involving both wild-type and genetically modified mice and - much to my own surprise - an in-vivo exercise part. And secondly, the results provi...
