Prior studies in both fibroblasts from insulin- resistant non-insulin-dependent diabetes mellitus patients and transfected cells indicate that overexpression of membrane glycoprotein PC-1 reduces IR tyrosine kinase activity.

In transfected MCF-7 cells, 125I-labeled insulin binding and IR content were unchanged, and PC-1 overexpression did not influence IGF-1 stimulation of IGF-1 receptor autophosphorylation.

This interaction was greater for the Q allele than for the K allele (P < 0.01), suggesting that direct PC-1-IR interactions are important for the PC-1 inhibitory effect on insulin signaling.

We measured PC-1 levels in these muscle samples to determine whether PC-1 content is elevated in this primate model of insulin resistance.

Variants of ENPP1 are associated with infantile arterial calcification, obesity, and insulin resistance.

Therefore, we suggest that the functional interactions between ALP and PC-1 may link insulin resistance to vascular calcification.

A common functional ENPP1 K121Q polymorphism has been suggested to contribute to insulin resistance, obesity and type 2 diabetes (T2D) in various ethnic groups.

Plasma cell membrane glycoprotein-1 or ectonucleotide pyrophosphatase/phosphodiesterase (PC-1/ENPP1) has been shown to inhibit insulin signaling, and its genetic polymorphism or increased expression is associated with type 2 diabetes in humans.

Since patients with phosphodiesterase/pyrophosphatase deficient PC-1 manifest abnormal calcification, enhancing insulin signaling by inhibiting PC-1 for the treatment of diabetes will be feasible only if PC-1 phosphodiesterase/pyrophosphatase activity needs not be significantly diminished.

In HEK293 cells stably expressing recombinant insulin receptor or insulin-like growth factor 1 (IGF1) receptor, transient expression of wild-type full length PC-1 (PC-1.FL.WT) but not the T256A or T256S mutants inhibits insulin signaling without affecting IGF1 signaling.

Together, these results suggest that the inhibition of insulin signaling by PC-1 is somewhat specific and is dependent upon the enzymatic activity of the phosphodiesterase/pyrophosphatase.

The Q allele of ENPP1 K121Q is associated with hyperglycemia and insulin resistance in whites.

This positive modulation of ENPP1 expression is paralleled by a reduced insulin-induced IR and IRS-1 phosphorylation.

Taken together these data suggest that HSP70, by affecting ENPP1 expression, may be a novel mediator of altered insulin signaling.
