MED15 protein overexpression in HCC specimens. (A) Hematoxylin and eosin staining of non-tumor liver and HCC specimens. (B) Immunohistochemical staining of non-tumor liver and HCC specimens. High MED15 protein expression was observed in HCC specimens, while adjacent non-tumor specimen presented negative or weak expression. MED15 expression appeared as granular brown-colored staining in the nuclei of tumor cells. Representative images with original magnification at ×200 and ×400 are shown. MED15, mediator complex subunit 15; HCC, hepatocellular carcinoma.
