Fig. 3From: BKCa participates in E2 inducing endometrial adenocarcinoma by activating MEK/ERK pathwayRepresentative immunohistochemical staining showed BKCa, ERK1/2 and p-ERK1/2 expressions in type I endometrial carcinoma tissues and atypical endometrial hyperplasia tissues using serial section technique. Simultaneously increased BKCa, ERK1/2, p-ERK1/2 expressions were observed in the representative cases with type I endometrial cancer (abc) and atypical endometrial hyperplasia tissues (def). The negative expressions of these proteins were shown in normal endometrium (ghi). Magnification × 200Back to article page
