Figure 1.

Immunohistochemical demonstration of ASK1 and claudin-6 protein expression in human cervical carcinoma and adjacent tissue (A). ASK1 was highly expressed in the cytoplasm of epithelial cells adjacent to cervical carcinoma but was expressed at low levels in cancer tissue itself (B, C). The strong expression of claudin-6 in the membrane of tissues adjacent to human cervical carcinoma compared to low expression of claudin-6 in human cervical carcinoma tissues (D).
