1	16407220	These data suggest that LKB1 is required for PKCzeta-enhanced AMPK activation.
2	16407220	Further, direct mutation of Ser428 of LKB1 into alanine, like the kinase-inactive LKB1 mutant, abolished ONOO- -induced AMPK activation.
3	17083919	When analyzed by immunoblotting with the antibody against Thr172-phosphorylated AMPK, the phosphorylation of AMPK was increased (2.5-fold) and decreased (0.4-fold) in cells expressing CA and DN LKB1, respectively, as compared with Lac-Z expressing control cells.
4	17083919	Immunoprecipitation experiments, using isoform-specific antibody, revealed these alterations of AMPK phosphorylation to be attributable to altered phosphorylation of AMPK alpha2, but not alpha1 catalytic subunits, strongly suggesting the alpha2 catalytic subunit to be the major substrate for LKB1 in mammalian cells.
5	17083919	In addition, adiponectin or AICAR-stimulated AMPK phosphorylation was inhibited by overexpression of DN LKB1, while phenformin-stimulated phosphorylation was unaffected.
6	17083919	These results may explain the difference in AMPK activation mechanisms between AMP and phenformin, and also indicate that AMPK phosphorylation by LKB1 is involved in AMP-stimulated AMPK activation.
7	17083919	These results demonstrate that LKB1 is a crucial regulator of AMPK activation in muscle and liver cells and, therefore, that LKB1 activity is potentially of importance to our understanding of glucose and lipid metabolism.
8	20713714	Muscle contraction increased sucrose nonfermenting AMPK-related kinase (SNARK) activity, an effect blunted in the muscle-specific LKB1 knockout mice.
9	20142099	Moreover, Fyn kinase directly phosphorylated LKB1 on tyrosine 261 and 365 residues, and mutations of these sites resulted in LKB1 export into the cytoplasm and increased AMPK phosphorylation.
10	18063812	In addition, direct mutagenesis of either Ser428 or Ser307 of LKB1 into alanine, like the kinase-dead LKB1 mutant, abolished both TPr-stimulated AMPK activation and coimmunoprecipitation.
11	18063812	We conclude that TPr stimulation triggers reactive oxygen species-mediated LKB1-dependent AMPK activation, which in return inhibits cellular protein synthesis in VSMCs.
