Correlation between apelin and albuminuria.

<p>A: The apelin concentration in serum was positively correlated with albuminuria (R = 0.78, *<i>p</i><0.05). B: The apelin concentration in serum was significantly increased in patients with type 2 diabetes (2DM, n = 60) compared to healthy people (control, n = 32). The data are expressed as the means±SD (*<i>p</i><0.05 vs. control grou ). C: The graphs show the promoting effect of apelin on FITC-BSA passing through the glomerular endothelial cell monolayers at the indicated time point. The data are expressed as the means±SD (n = 6, *<i>p</i><0.01 vs. control group).
