Fig 1: KCNK9 and KCNA6 expression in the eutopic endometrium of patients with adenomyosis and controls. (A) Representative immunohistochemical (IHC) staining of KCNK9 and KCNA6 proteins. Endometrial glands and vessels are indicated by arrows and triangles, respectively. S, stroma. Comparison of KCNK9 and KCNA6 expression in endometrial glands (B) and vessels (C). The expression was scored as follows: intensity x area of positively stained cells (%). Significant high expression of KCNK9 in the endometrial glands (p = 0.004) and endometrial vessels (p < 0.001) in adenomyosis.
