We have characterized a plasma membrane phosphatidylinositol 4,5-bisphosphate (PIP2)-specific phospholipase C (PLC) and a cytosolic phosphatidylinositol (PI)-specific PLC in human liver.

Insulin and insulin-like growth factors (IGF-I and IGF-II) in the presence and absence of GTP gamma S did not stimulate PIP2-PLC or PI-PLC in plasma membranes and cytosol preparations nor phosphoinositide breakdown in isolated human hepatocytes.

Furthermore, the increased PIP2-PLC in diabetic liver may result in: (a) increased intracellular concentrations of IP3 and thus increased Ca2+, which has been postulated to induce insulin resistance; and (b) increased diacylglycerol and thus increased protein kinase C which phosphorylates the insulin receptor at serine residues inactivating the insulin receptor kinase.

This change was reflected by a significant increase in the total- and protein-sulfhydryl content, as well as in the free sulfhydryl groups of the major protein disulfide isomerases (PDIs), the 58 kDa PDI and the 57 kDa ERp57 but not other chaperones.

Among the most relevant results stand out the normalization by intensive ATV treatment of the expression of proteins that modulate inflammation and thrombosis such as protein disulfide isomerase ER60 (PDI), Annexin I, and prohibitin, or that have other protective effects as HSP-70.

We used β-cell lines and isolated murine islets to determine the effect of ethanol on insulin content and secretion at low- and high-glucose concentrations, in the presence of KCl, diazoxide, tolbutamide, and regulators of cyclic AMP and protein kinase C (PKC).

We also determined the gene expression of insulin; pancreas duodenum homeobox 1; and endoplasmic reticulum (ER) stress markers, such as Chop, ERp57, glucose-regulated protein 78/binding immunoglobulin protein, and inositol 1,4,5-triphosphate receptors.

Among these proteins, two of the decreased proteins are involved in endoplasmic reticulum (ER) stress-related unfolded protein response, GRP78 and protein disulfide isomerase A3, and it was revealed that the decreased GRP78 expression in the liver of diabetic db/db mice is due to the reduction of GRP78 protein synthesis rather than RNA transcription.

In addition, we found that the treatment of human hepatocyte HepG2 cells with oleic acid decreased the expression of GRP78, and attenuated the activation of AKT by insulin stimulation.

|
These results suggest that decreased GRP78 expression may induce resistance to insulin by inhibiting the AKT activation, and plays an important role in the development of type 2 diabetes.
