Loss of EphA7 Expression in Basal Cell Carcinoma by Hypermethylation of CpG Islands in the Promoter Region

Figure 1

EphA7 expression in BCC was checked using immunohistochemistry. (a) Positive expression of EphA7 in normal basal cells; magnification, 400x. (b) Positive expression of EphA7 in basal cell carcinoma cells; magnification, 400x. (c) Negative expression of EphA7 in basal cell carcinoma cells; magnification, 400x. (d) Loss of expression of EphA7 protein in basal cell carcinoma cells (arrows) compared to that in normal basal cells; magnification, 200x.
