Abstract：
:We have compared insulin binding by heart cells at 7 and 14 days of development. Species specificity, optimum pH, temperature relationships, and time to equilibrium for binding of insulin were the same in both 7 and 14-day systems. Curvilinear Scatchard plots for chicken insulin binding were demonstrated. Binding affinities and capacities were calculated based on a two-receptor model including a specific high-affinity receptor and a less specific low-affinity receptor that bound insulin and other growth peptides. Apparent association constants (K(A)) were 4.0 and 0.05 nM(-1) and binding capacities were 600 and 9000 sites per cell for high- and low affinity receptors, respectively. We have also investigated the ability of insulin to regulate binding to its own receptors. Chick heart cells from 7- and 14-day embryos, cultured for 44 hr in insulin-enriched medium (3.4 microM), bound 50% less insulin (down-regulated) than control cells. At both developmental stages, down regulation was primarily a reduction in binding to the high-affinity receptor. The low-affinity receptor was less susceptible to down regulation and retained its ability to mediate maximal insulin stimulation of amino acid transport.
