Tivation was detected by a commercial ELISA kit (Invitrogen) or by Western blot evaluation making use of phosphorylationspecific antibodies to AMPK at Thr172 (pAMPK) and its substrate, pACC, from Cell Signaling Technologies. Complete scans of all Western blots indicating regions shown within the respective principal figures are shown in Fig. S9. Immunofluorescence evaluation was performed applying pancreatic tissue sections and isolated pancreatic islets obtained from female C57BL/6 WT and ob/ob mice at age 7 wk (Shizuoka, Japan), too as INS1 cells. Information regarding antibodies employed within the present study is provided in Tables S1 and S2. All animal experimental procedures had been carried out in accordance using the recommendations in the University Committee on Animal Sources at Seoul National University (approval no. SNU12021602). Confocal images were obtained working with a FluoView 1000 (Olympus) or TCSSP2 (Leica) confocal microscope and processed with Leica Confocal Software program. See SI Components and Techniques for facts on electrophysiological measurements making use of the patch clamp strategy, intracellular [Ca2] measurement employing microfluorimetry with Fura2acetoxymethyl ester (AM), composition of experimental solutions, drugs, and statistical analysis.
