Figure 6.
Insulin effects on phosphate transport kinetics in VSMC in the presence of A. sodium chloride (inset shows the points at lower Pi concentrations) or B. choline chloride (n=3). Sodium-phosphate co-transport was measured in response to 0 to 5 mM extracellular phosphate (Pi). Insulin increases Vmax but not Km (p<0.05 vs. control). Black squares, solid line = insulin; white squares, dotted line = control.
