For chronic clenbuterol studies performed with transgenic mice, baseline ipGTTs were performed with control and the indicated KO mice as described above. Two days later, both control and mutant mice started to consume clenbuterol drinking water. After 5 days on clenbuterol water, mice were subjected to another ipGTT. AMPK and mTORC2-dependent signaling pathways differentially regulate Plin3 expression38.

Quadriceps muscles were isolated 30 min later and processed for immunoblotting experiments. As previously observed in the refeeding experiment (Fig. 3l), clenbuterol treatment had a significant effect on the phosphorylation status of SKM glycogen synthase (GS) and the upstream kinase, GSK3β (Supplementary Fig. 10a–c).
