AMPK activation is independent of classical pathways. A Western blots of p-AMPKα, AMPKα, p-ACC, ACC, p-LKB1, LKB1, p-CAMKK2, CAMKK2, p-TAK1, TAK1, and PP2C of primary hepatocytes subjected to PA stimulation at the indicated conditions. n = 3 replicates. B Western blots of p-AMPKα, AMPKα, p-ACC, ACC, p-LKB1, LKB1, p-CAMKK2, CAMKK2, p-TAK1, TAK1, and PP2C in the livers of HFD-fed mice treated with vehicle or honokiol. n = 5 mice per group. C Western blots of p-AMPKα, AMPKα, p-ACC, ACC, p-LKB1, LKB1, p-CAMKK2, CAMKK2, p-TAK1, TAK1, and PP2C in the livers of CDAHFD-fed mice treated with vehicle or honokiol. n = 5 mice per group. D Western blots of p-AMPKα, AMPKα, p-ACC, ACC, p-LKB1, LKB1, p-CAMKK2, CAMKK2, p-TAK1, TAK1, and PP2C in the livers of MCD-fed mice treated with vehicle or honokiol. n = 5 mice per group. E Representative image of the oxygen consumption rate (OCR) of primary hepatocytes subjected to DMSO or honokiol at the indicated conditions. n = 3 replicates. Omy, oligomycin, F1F0 ATP synthase inhibitor. FCCP, mitochondrial uncoupler. Rot, retenone, complex I inhibitor. AA, antimycin A, complex II inhibitor. F ATP, ADP, and AMP in the livers of HFD-fed mice treated with vehicle or honokiol. n = 6 mice per group. Student’s t-test was applied for statistical analysis. G ATP, ADP, and AMP in the livers of CDAHFD-fed mice treated with vehicle or honokiol. n = 6 mice per group. Student’s t-test was applied for statistical analysis. H ATP, ADP, and AMP in the livers of MCD-fed mice treated with vehicle or honokiol. n = 6 mice per group. Student’s t-test was applied for statistical analysis
