Brief glutamatergic stimulation of neurons from fetal mice, cultured in vitro for 6 days, activates the mTOR-S6 kinase, ERK1/2 and Akt pathways, to an extent approaching that elicited by brain-derived neurotrophic factor.

In contrast, sustained glutamatergic stimulation inhibits ERK, Akt, and S6K.

Added singly, dopamine gives slight, and norepinephrine a more significant, activation of ERK and S6K; both catecholeamines, however, enhance glutamatergic activation of S6K but not ERK.

Elongation factor 2 (EF2) is phosphorylated and inhibited by the eEF2 kinase (CaM kinase III); the latter is inhibited by the S6K or Rsk.

Diabetes increased constitutive HSC70 mRNA, and decreased HSP90 and glucose-regulated protein 75 (GRP75) mRNA without affecting protein levels.

LA had no significant effect on brain HSPs, although LA increased HSC70 and HO-1 mRNA in diabetic animals and decreased HSC70 mRNA in non-diabetic animals.

Eukaryotic translation elongation factor-2, essential for protein synthesis, was decreased by diabetes and suggesting a mechanism for the impaired HSP response related to translocation of the nascent chain during protein synthesis.

High glucose stimulated mTORC1 to promote key events in the initiation and elongation phases of mRNA translation: binding of eIF4A to eIF4G, reduction in PDCD4 expression and inhibition of its binding to eIF4A, eEF2 kinase phosphorylation, and dephosphorylation of eEF2; these events were inhibited by NaHS.

NaHS induction of AMPK phosphorylation was inhibited by siRNA for calmodulin kinase kinase β, but not LKB1, upstream kinases for AMPK; STO-609, a calmodulin kinase kinase β inhibitor, had the same effect.

As a result, four down-regulated protein species named elongation factor 2 (EEF2), carboxymethyl-cofilin-1 (cofilin-1), acetyl-eukaryotic translation initiation factor 5A-1 (acetyl-EIF5A) and barrier-to-autointegration factor, and five up-regulated protein species named heat shock protein beta-1 (HSP27), phospho-HSP27, phospho-stathmin, Nicotinate-nucleotide pyrophosphorylase and 1,2-dihydroxy-3-keto-5-methylthiopentene dioxygenase were identified.

Thus, we investigated the expression of leptin and leptin receptor (LEPR), as well as the activation state of signaling proteins regulating protein synthesis, such as mTOR, S6 Kinase, EIF4E-BP1, EIF4E, and eEF2 by measuring protein phosphorylation by immunoblot. [³H]-Leucine incorporation into protein also was determined in trophoblastic placenta explants from GDM and control pregnancy.

|
We found that leptin and LEPR expression are increased in placentas from GDM and the translation machinery activity as well as [³H]-leucine incorporation into protein were higher in placentas from GDM compared with placentas from control pregnancy.

|
The increased expression of leptin and LEPR may contribute to these effects.
