15534876 Elo MA, Karjalainen HM, Sironen RK, Valmu L, Redpath NT, Browne GJ, Kalkkinen N, Helminen HJ, Lammi MJ: High hydrostatic pressure inhibits the biosynthesis of eukaryotic elongation factor-2. J Cell Biochem. 2005 Feb 15;94(3):497-507.

Cycloheximide addition after 4 h-pressure treatment suggested that the half-life of eEF-2 protein was shorter in pressurized cells. eEF-2 is responsible for the translocation of ribosome along the specific mRNA during translation, and its phosphorylation prevents the ribosomal translocation.

Although L-[3H] arginine uptake measured in cultured chick retina cells incubated in the presence of cycloheximide (CHX, a protein synthesis inhibitor) was inhibited approximately 75% at equilibrium, quantitative thin-layer chromatography analysis showed that free intracellular L-[3H] arginine was six times higher in CHX-treated than in control cultures.
Western blot analysis revealed that NMDA stimulates the phosphorylation of eukaryotic elongation factor 2 (eEF2, a factor involved in protein translation), an effect inhibited by (+)-5-methyl-10,11-dihydro-5H-dibenzo [a,d] cyclohepten-5,10-imine maleate (MK801).

Since it was blocked by the translation inhibitor cycloheximide, we examined whether sustained exposure to glibenclamide activates translational factors by calcium-dependent signalling pathways.
RESULTS: A 24 h exposure to glibenclamide induced activation of four translation factors, i.e. phosphorylation of eukaryotic initiation factor (eIF) 4e binding protein 1 and ribosomal protein S6 (rpS6), and dephosphorylation of eIF-2alpha and eukaryotic elongation factor 2.

Here, we provide evidence that eIF2alpha phosphorylation is required for phosphorylation of eukaryotic elongation factor 2 (eEF-2) during nutrient starvation.

Truncated actin isoforms were found to abound in the encysting cell and the levels of translation elongation factor 2 (EF2) were sharply decreased, indicating that the rate of protein synthesis must be low at this stage.
The protease inhibitors PMSF and E64d inhibited the onset of encystment, whereas the protein synthesis inhibitor cycloheximide was ineffective.

Finally, we show that the ability of energy depletion (which impairs mTOR signaling in TSC2+/+ cells) to increase the phosphorylation of eukaryotic elongation factor 2 is also independent of TSC2.
