Figure 1From: Increased expression of the retinoic acid-metabolizing enzyme CYP26A1 during the progression of cervical squamous neoplasia and head and neck cancerCYP26A1 expression in cervical squamous intraepithelial neoplasia. Representative images of hematoxylin-eosin staining (A, C, E, G, and I) and immunohistochemistry of CYP26A1 (B, D, F, H, and J). CYP26A1 expression was evaluated in non-neoplastic (normal) squamous epithelium (A, B), epithelium with mild (C, D), moderate (E, F), and severe (G, J) dysplasia, as well as squamous cell carcinoma in situ (I, J). Original magnification: ×40 (A, B, C, D, and E), ×100 (F, G, H, I, and J).Back to article page
