Expression of LRP-2 at the CP with age. (A) Graph of the log-transformed normalized expression of LRP-2 with respect to age, n = 8 per age group. One-way ANOVA revealed a significant decrease (p = 0.0005) with age on LRP-2 expression. Significance was reached between 3 and 9, 12, 20, 30, and 36 mo. Error bars represent 95% confidence intervals for the means. (B) Semi-quantitative IHC for LRP-2 expression in grayscale units (GU). Mean staining intensity was significantly decreased (p < 0.05) for the age groups, n = 5 per age group. (C) IHC of LRP-2 expression at 3 mo (top), 20 mo (center), and 36 mo (bottom) old rats. Staining is localized to the apical membrane (arrows), and is also seen subapically.
