Dubbelhuis et al., FEBS Lett 2002 : Insulin dependent phosphorylation of protein kinase B is not affected by AMPK activation
Kovacic et al., J Biol Chem 2003 : Because insulin is able to activate Akt and inactivate AMP activated protein kinase (AMPK) in the heart, we hypothesized that Akt can regulate the activity of AMPK ... Taken together, this study suggests that there is cross-talk between the AMPK and Akt pathways and that Akt activation can lead to decreased AMPK activity
Ouchi et al., J Biol Chem 2004 (Neovascularization, Pathologic) : Dominant negative AMPK also inhibited adiponectin induced Akt phosphorylation, suggesting that AMPK is upstream of Akt
King et al., Am J Physiol Heart Circ Physiol 2005 (Hyperglycemia) : Previous studies have demonstrated that AMPK can be inhibited by protein kinase B (PKB) ; however, PKB was activated by dobutamine and the elevated insulin that accompanied hyperglycemia, but there was no effect on AMPK activity
Baumann et al., Exp Cell Res 2007 (Multiple Myeloma) : Activation of AMPK inhibited basal extracellular signal regulated kinase ( ERK ), mammalian target of rapamycin (mTOR) and P70S6 kinase ( P70S6K ) as well as AKT phosphorylation, and blocked IL-6, IGF-1, and HS-5 stromal cell conditioned medium induced increase of cell growth
Memmott et al., Cancer Res 2008 (Carcinoma, Non-Small-Cell Lung...) : Here, we show that lipid based Akt inhibitors, phosphatidylinositol ether lipid analogues ( PIA ), activate AMPK independently of LKB1 ... PIAs activated AMPK in LKB1-mutant non-small cell lung cancer ( NSCLC ) cell lines with similar concentration dependence as that required to inhibit Akt ... However, AMPK activation was independent of Akt inhibition
Chan et al., J Biol Chem 2008 (Cardiomegaly) : Taken together, our data suggest that resveratrol exerts anti-hypertrophic effects by activating AMPK via LKB1 and inhibiting Akt , thus suppressing protein synthesis and gene transcription
Youn et al., Circ Res 2009 : These data indicate that AMPK and AKT are both downstream of PI3K and that AKT activation is partially dependent on AMPK

Liu et al., Cell Signal 2010 : Using specific inhibitors to key kinases of both pathways and PKCzeta small interference RNA, protein kinase C zeta (PKCzeta) was found to regulate insulin stimulated protein kinase B (PKB) activation and inhibit AMPK activity on dorsal cell surface ...

Becker et al., Diabetes 2010 (Body Weight...) : Chemerin reduced insulin stimulated Akt1 phosphorylation and activation of 5'AMP activated protein kinase (AMPK) in the skeletal muscle, but had no effect on Akt phosphorylation and insulin stimulated AMPK activation in the liver and gonadal adipose tissue
Memmott et al., Cancer prevention research (Philadelphia, Pa.) 2010 (Carcinoma...) : In lung tissue, metformin did not activate AMPK but inhibited phosphorylation of insulin-like growth factor-I receptor/insulin receptor ( IGF-1R/IR ), Akt , extracellular signal regulated kinase ( ERK ), and mTOR
Leclerc et al., Journal of molecular signaling 2010 : AMPK induced activation of Akt by AICAR is mediated by IGF-1R dependent and independent mechanisms in acute lymphoblastic leukemia ... We found that AICAR induced AMPK activation resulted in up-regulation of P-Akt ( Ser473 and Thr308 ) and decrease of P-mTOR ( Ser2448 ) expression and downstream signaling ... We determined that activation of P-Akt ( Thr308 ) was mediated by AMPK induced IGF-1R activation via phosphorylation of the insulin receptor substrate-1 (IRS-1) at Ser794 ... Co-treatment of AICAR plus HNMPA ( AM ) 3 prevented AMPK induced up-regulation of P-Akt ( Thr308 ) but did not alter the activation of P-Akt ( Ser473 ) ... Inhibition of AMPK using compound-C resulted in decreased P-Akt expression at both residues, suggesting a central role for AMPK in Akt activation
Pulinilkunnil et al., J Biol Chem 2011 : Both PKA and AKT inhibitors attenuated AMPK Ser ( 485/491 ) phosphorylation resulting from a-adrenergic blockade and prevented decreases in AMPK activity
Kuznetsov et al., Mol Cancer Ther 2011 (Precursor Cell Lymphoblastic Leukemia-Lymphoma) : Under these conditions, the concomitant inhibition of Akt , a cellular antagonist of AMPK, leads to further upregulation of AMPK activity and alleviates AICAr plus MTX induced ER stress and apoptosis

Ginion et al., Am J Physiol Heart Circ Physiol 2011 (Insulin Resistance) : In conclusion, although the insulin sensitizing effect of AMPK on PKB/Akt is explained by the inhibition of the insulin induced negative feedback loop, its effect on glucose uptake is independent of this mechanism ...
