Hence, in the retina of diabetic rats, as in the retina of diabetic human donors, IGF-I mRNA levels are substantially lower than in age-matched nondiabetic controls, whereas IGF-IR activation and signaling are not affected, at least for some time.

This finding suggests that in the diabetic retina, the activation of the IGF-IR is modulated by influences that compensate for, or are compensated by, decreased IGF-I synthesis.

Transducing cardiomyocytes with antisense Hsp60 oligonucleotides reduced Hsp60 expression, decreased the abundance of IGF-1R, attenuated IGF-1R autophosphorylation, and suppressed the pro-survival action of IGF-1 in cardiomyocytes.

The effects of IGF-1 are mediated principally through the IGF-1R but are modulated by complex interactions with multiple IGF binding proteins that themselves are regulated by phosphorylation, proteolysis, polymerization, and cell or matrix association.

This effect of IGF-I was specifically mediated by the IGF-IR, because IGF-I did not induce TDAG51 expression in NIH-3T3 cells overexpressing a dominant-negative IGF-I receptor.

Insulin and IGF-I increase association of the IR and IGF-IR with PyVmT, enhance tyrosine phosphorylation of PyVmT and augment the recruitment of Src and PLCgamma(1) to PyVmT.

Given that some of the modifications introduced into insulin analogues are located in a domain involved in a potential interaction with the insulin-like growth factor-I receptor (IGF-IR), it has been postulated that certain analogues may display IGF-I-like activities.

In wild-type preadipocytes, which express predominantly IGF1R, microarray analysis revealed approximately 500 IGF-1 regulated genes (p < 0.05).

|
Measurement of the 50 most highly regulated genes by quantitative PCR did not reveal a single gene regulated uniquely via the IR or IGF1R using cells expressing exclusively IGF-1 or insulin receptors.

|
Thus, IR and IGF1R act as identical portals to the regulation of gene expression, with differences between insulin and IGF-1 effects due to a modulation of the amplitude of the signal created by the specific ligand-receptor interaction.

GH and IGF-I exert their biological effects through binding to respective receptors (GHR and IGF-IR) and subsequently engaging downstream signaling pathways.
