[PDF][PDF] Brown adipose expansion and remission of glycemic dysfunction in obese SM/J mice

…, S Oyama, CLS Pierre, H Schmidt, JP Wayhart… - Cell reports, 2020 - cell.com
We leverage the SM/J mouse to understand glycemic control in obesity. High-fat-fed SM/J
mice initially develop poor glucose homeostasis relative to controls. Strikingly, their glycemic …
