Neither basal nor insulin-stimulated p70(S6K) activity, a signalling element lying downstream of mTOR, were modified by STZ-diabetes.

The prosurvival effects of GLP-2 on LY294002-induced cell death were independent of Akt, p90(Rsk), or p70 S6 kinase activation; were mimicked by forskolin; and were abrogated by inhibition of protein kinase A (PKA) activity.

EGCG also mimics insulin by increasing phosphoinositide 3-kinase, mitogen-activated protein kinase, and p70(s6k) activity.

However, the signaling mechanism by which glucose induces Erk-1/2 and p70(S6K) phosphorylation activation is undefined.

Increased glucose metabolism increases [Ca(2+)](i) and [cAMP], and it was investigated if these secondary signals were linked to glucose-induced Erk-1/2 and p70(S6K) activation in pancreatic beta-cells.

In contrast, glucose-induced p70(S6K) activation, in the same beta-cells, was mediated by a distinct signaling pathway independent of Ca(2+)/cAMP, most likely via mTOR-kinase acting as an "ATP-sensor."

Neither protein level nor insulin-stimulated p70(S6k) activation were modified by STZ-diabetes.

Interestingly, acetaldehyde enhanced p70(S6K) activation and depressed 4E-BP1 phosphorylation, the effect of which was blunted and exaggerated, respectively, by rapamycin.

|
Collectively, these data suggested that acetaldehyde did not adversely affect glucose uptake despite inhibition of insulin signaling cascade at the levels of Akt and mTOR, possibly due to presence of certain mechanism(s) responsible for enhanced p70(S6K) phosphorylation.

GDM women had decreased skeletal muscle insulin-stimulated insulin receptor and insulin receptor substrate 1 (IRS1) tyrosine activation and reduced IRS1, concomitant with increased basal IRS1 serine phosphorylation and basal p70 S6-kinase (S6K1) activation, which resolved postpartum.

In conditions of over-nutrition, increased insulin (INS) and angiotensin II (Ang II) activate mammalian target for rapamycin (mTOR)/p70 S6 kinase (S6K1) signaling, whereas chronic alcohol consumption inhibits mTOR/S6K1 activation in cardiac tissue.
