The levels of TfR1 mRNA were significantly increased in SCD mice (Figure 2A, TfR1-Actb delta Ct, −4.26 ± 0.14 in SCD vs. −4.69 ± 0.12 in control, p = 0.0421), but the levels of mRNA expression of the Slc11a2 gene that encodes DMT1 were similar in SCD and control mice (Figure 2B, Slc11a2-Actb delta Ct, −1.68 ± 0.26 in SCD vs. 1.71 ± 0.11 in control, p = 0.9236). Here, SLC11A2 is linked to Schnyder corneal dystrophy.
