IDE mRNA and protein expression in Z310 cells following Pb exposure. Z310 cells were treated with 10 μM Pb for 24 h or 48 h. A: IDE mRNA expression. No significant difference was observed in the mRNA expression between the Pb-exposed and control groups. B: Representative western blots of IDE protein expression in controls and cells treated with Pb (10 μM) for 24 and 48 h. C: IDE expression estimated from the corresponding band densities (B) and normalized to those of β-actin. No significant difference in IDE protein expression was found between Pb-treated and control cells. Data represent mean ± SD, n = 3. The data are representative of triplicate experiments.
