Effect of Vldlr overexpression on Dab1 mRNA expression. qRT-PCR quantification of Dab1 mRNA expression in prefrontal cortex, hippocampus and cerebellum of wild-type (Wt) and transgenic (Tg) adult (2 to 3 months) rats from transgenic line 1. Relative Dab1 expression was obtained by normalizing to Actb from the same cDNA. The results are expressed as a ratio of Wt expression, resulting in a Wt ratio of 1. Bars represent mean ± SEM (n = 6 per genotype). * P < 0.05 between Wt and Tg rats.
