Figure 3. QRT–PCR analysis in Li+-treated retinal explants and in β-cat^Act mutant eyes of gene expression. Validation of upregulated (A) and downregulated (B) genes from the Li+-modulated data set. A total of three independent experiments were performed in triplicate (n=3). Data are normalized to Gapdh and 18S and presented as fold-change relative to control explant cultures and wild-type littermates±SD *p<0.05.
