Figure 4. Nanoceria inhibit the activation of Akt in the retina of Vldlr−/− mouse.
Wt and Vldlr−/− mice were injected with 1μl of 1 mM nanoceria on P28 and the retinas were collected at P35. Uninjected Wt and Vldlr−/− mice at P35 served as controls. Retinal proteins (10μg) were subjected to 10% SDS-PAGE and Western blot analysis for the detection of phosphorylated p-Akt (A). The same membranes were then stripped and reprobed with anti-Akt antibody which detects total protein levels, or anti-actin antibody, respectively. The blots were scanned, densitometry analysis performed, and the normalized results are presented as the mean ± S.E.M of the p-Akt/Actin (B) and Akt/Actin (C) ratio from 3 independent experiments.
