Coat color correlates with Cre expression in the RPE of constitutive Dicer1flox/floxCreB+ and Dgcr8flox/floxCreB+ mice.
A, images of mature RPE-specific Dicer1flox/floxCreB+ and Dgcr8flox/floxCreB+ mice reveal variations in coat color. B, quantitative RT-PCR analysis of Cre recombinase gene expression in the RPE/choroid of 8-week-old Dicer1flox/floxCreB+ and Dgcr8flox/floxCreB+ mice with different proportions of white and black fur, along with control littermates revealed that mice with more white fur also exhibited higher Cre expression in the RPE/choroid. *, p < 0.05; **, p < 0.001.
