Fig. 2From: Wnt3a ligand facilitates autophagy in hippocampal neurons by modulating a novel GSK-3β-AMPK axisIncreased AMPK activity by Wnt3a ligand requires canonical FzR-LRP5/6 and GSK-3β inhibition and does not affect the turnover of phosphatase PP2Ac. a After 30 min, Wnt3a ligand induces AMPK activation, which was abolished by Dkk1 and TCS183 pretreatment. b Measurement of PP2A catalytic subunit levels indicates no changes during time-course treatment. The data are expressed as the mean ± S.E.M. of three independent experiments, **p < 0.001, n.s., non-significantBack to article page
