PF-4708671 activates AMPK independently of p70S6K1 inhibition. [PDF]
The P70 ribosomal protein S6 kinase 1 (P70S6K1) is activated by the mammalian target of rapamycin (mTORC1) and regulates proliferation, growth, and metabolism.

Phosphatidylinositol 3′-Kinase-independent p70 S6 Kinase Activation by Fibroblast Growth Factor Receptor-1 Is Important for Proliferation but Not Differentiation of Endothelial Cells [PDF]
p70(s6k) has a role in cell cycle progression in response to specific extracellular stimuli. The signal transduction pathway leading to activation of p70(s6k) by fibroblast growth factor receptor-1 (FGFR-1) was examined in FGF-2-treated rat L6 myoblasts. p70(s6k) was activated in a biphasic and rapamycin-sensitive manner.

Oncogenic Raf-1 Activates p70 S6 Kinase via a Mitogen-activated Protein Kinase-independent Pathway [PDF]
Cell proliferation requires the co-ordinate triggering of several protein kinases of Ser/Thr specificity such as p70 S6 kinase (S6K), which phosphorylates the ribosomal S6 protein and thus increases translation of mRNAs with polypyrimidine tracts. The multiplicity of signaling pathways leading to p70 S6K activation are not fully elucidated.

Phosphorylation of IRS1 at serine 307 in response to insulin in human adipocytes is not likely to be catalyzed by p70 ribosomal S6 kinase. [PDF]
The insulin receptor substrate-1 (IRS1) is phosphorylated on serine 307 (human sequence, corresponding to murine serine 302) in response to insulin as part of a feedback loop that controls IRS1 phosphorylation on tyrosine residues by the insulin receptor.

Distinct signalling pathways mediate insulin and phorbol ester- stimulated eukaryotic initiation factor 4F assembly and protein synthesis in HEK 293 cells [PDF]
Stimulation of serum-starved human embryonic kidney (HEK) 293 cells with either the phorbol ester, 12-O-tetradecanoylphorbol-13-acetate (TPA), or insulin resulted in increases in the phosphorylation of 4E-BP1 and p70 S6 kinase, eIF4F assembly, and ...

Autophagy processes are dependent on EGF receptor signaling [PDF]
Autophagy is a not well-understood conserved mechanism activated during nutritional deprivation in order to maintain cellular homeostasis. In the present study, we investigated the correlations between autophagy, apoptosis and the MAPK pathways in ...
