Overall, the results indicated that ABA has positive effect on spatial learning and memory performance and elicits anti-anxiety effects which are performed, at least in part, through PI3K/PKC signaling pathway.
Here, we demonstrate that treatment with mTOR inhibitors result in the removal of negative feedback loops and up-regulates pro-proliferative phosphatidylinositol 3-kinase (PI3K)-Akt and PI3K-extracellular signal-regulated kinase (ERK) signaling in rat and mouse PKD models.
Therefore, we identify Inpp5e as an essential inhibitor of the PI3K/Akt/mTORC1 signaling axis in renal epithelial cells, and demonstrate a critical role for Inpp5e-dependent mTORC1 regulation in PKD suppression.
Phosphoinositide 3- kinase (PI3K)/AKT signaling activates mammalian target of rapamycin complex 1 (mTORC1) and hyperactivation of mTORC1 is a common event in PKD, however, mTORC1 inhibitors have yielded disappointing results in clinical trials.
