Figure 3.

Insulin receptor gene expression as estimated by real-time RT-PCR at various concentrations of insulin (+: 10 nM, ++: 500 nM) and glucose (+: 5.5 mM, ++: 17.5 mM). Only the effect of OxLDL is shown for IGF1. RU, relative units. *: p < 0.05 vs. all other values except for IGF1-treated cells. Means ± SEM of triplicates.
