We have investigated the roles of eukaryotic initiation factor 4E (eIF-4E), the cap-binding protein, and the translational regulator, PHAS-I, in the effects of insulin and alloxan-induced diabetes on protein synthesis in rat skeletal muscle.

|
The effects of both insulin and diabetes on PHAS-I binding to eIF-4E appeared to be due to changes in PHAS-I phosphorylation.

Neither insulin nor diabetes changed the phosphorylation state of eIF-4E.

The results indicate that the effects of both insulin and diabetes on protein synthesis in skeletal muscle involve modulation of the interaction of PHAS-I and eIF-4E.

Starvation and refeeding also altered the amount of eIF-4G that coimmunoprecipitated with eIF-4E.

Taken together, our results indicate that the exposure of cells to NaAsO2 resulted in cytotoxicity and cell death, at least in part, due to the inhibition of eIF4E gene expression leading to diminished cellular levels of critical genes such as cyclin D1.

Akt, mammalian target of rapamycin (mTOR), ribosomal-S6 kinase (p70(S6K)), the eukaryotic translation initiation factor 4E (eIF4E)-binding protein 1 (4E-BP1) and insulin receptor substrate (IRS)-2 were evaluated by Western blot analysis.

The hastening of mRNA translation initiation most likely results from a stimulation of mammalian target of rapamycin (mTOR) acting through its downstream effector proteins eukaryotic initiation factors (eIF)4E binding protein1 and possibly eIF4G to enhance assembly of eIF4G with eIF4E and 70-kDa ribosomal S6 kinase1.

By boosting the effective availability of the translation initiator eIF4E, mTORC1 activity promotes the translation of a number of "weak" mRNAs that code for proteins, often up-regulated in cancer, that promote cellular proliferation, invasiveness, and angiogenesis, and that abet cancer promotion and chemoresistance by opposing apoptosis.

|
4E-BP1 is a protein that, in its hypophosphorylated state, binds the mRNA cap-binding protein eIF4E and represses cap-dependent mRNA translation.

In the present study, Ins2(Akita/+) diabetic mice were used to test the hypothesis that hyperglycemia and elevated flux of glucose through the hexosamine biosynthetic pathway lead to increased O-GlcNAcylation and truncation of 4E-BP1 and consequently decreased eIF4E function in the liver.
