TAG content and lipolysis in βKO islets. A) Content of TAG of whole pancreas (top left) or isolated islets (top right), and Nile red staining for TAG in islets (bottom), scale: 50 µm. B) FA content in islets (left), and glycerol release from islets (right). Male mice, n=4–6. C) Content of TAG (top left), and Nile red and DAPI staining (top right), glycerol release (bottom left), and FA oxidation (bottom right) in INS 832/13 cells infected with adenoviral desnutrin-GFP or control GFP (n=3–4). Data are shown as mean ± SEM; * P<0.05, **P<0.01. See also Figure S3.
