Expression levels of immature neuron markers DCX and CR are downregulated in p50^−/− mice. A, DCX, CR, and α-tubulin immunoblotting of protein extracts from hippocampi of six wild-type and seven p50^−/− male mice, 3–4 months of age. B, Densitometric analysis of DCX and CR immunoreactivity in wt and p50^−/− mice normalized to the α-tubulin signal (ratio), showing a significant decrease for both proteins in mutant mice compared with wt control. Data represent mean ± SEM of three experiments. *p < 0.05.
