The Ras-ERK (extracellular signal-regulated kinase) and PI3K (phosphatidylinositol 3-kinase)-mTOR (mammalian target of rapamycin) signaling pathways are the cell’s chief mechanisms for controlling cell survival, differentiation, proliferation, ...

Here, we investigate whether changes in CRMP-2 expression, possibly regulated by mTOR-related signaling, correlates with neuronal growth and viability. Inhibition of mTOR and/or phosphoinositol-3-kinase (PI3K) led to deceased p-S6K, and p …

Jul 25, 2022 · As a substrate and major effector of the mammalian target of rapamycin complex 1 (mTORC1), the biological functions of ribosomal protein S6 kinase (S6K) have been canonically assigned for cell...

It has recently been reported that the phosphoinositide 3-kinase (PI3K)/Akt/mammalian target of rapamycin (mTOR) signaling pathway regulates neuronal differentiation of neural stem cells (NSCs) derived from rats or mice and is essential for the self-renewal of …

Aug 23, 2023 · In this review we highlight the major dysregulations in the PAM signaling pathway in cancer, and discuss the results of PI3K, AKT and mTOR inhibitors as monotherapy and in co-administation with other antineoplastic agents in clinical trials as a strategy for overcoming treatment resistance.

Jul 5, 2015 · We found that PI3K/Akt/mTOR signaling is essential for hNSC dopaminergic neuronal differentiation through activation of S6K. Our findings provide new insight into a novel regulatory mechanism of hNSCs and could help to clarify the mechanism of hNSC differentiation in the process of neurogenesis.

In many cases, autophagy is regulated by the phosphatidylinositol 3-phosphate kinase/AKT/mammalian target of rapamycin/p70 ribosomal protein S6 kinase (PI3K/AKT/mTOR/p70S6K) signaling pathway. However, whether this signaling pathway is involved in Aβ-induced autophagy in neuronal cells is not known.

May 20, 2013 · We discuss the identification and functional analysis of novel isoform of ribosomal protein S6 kinase – S6K2 and of mTOR kinase – mTOR, as well as their oncogenic properties.

Sep 15, 2017 · Here, we investigate whether changes in CRMP-2 expression, possibly regulated by mTOR-related signaling, correlates with neuronal growth and viability. Inhibition of mTOR and/or phosphoinositol-3-kinase (PI3K) led to deceased p-S6K, and p-S6 signals also reduced CRMP-2 expression.

Feb 18, 2010 · Our present study demonstrates that AMPK exerts dual effects on the PI3K pathway, stimulating PI3K/Akt and inhibiting mTOR/S6K.
