HIPK2 Overexpression and Its Prognostic Role in Human Papillomavirus-Positive Tonsillar Squamous Cell Carcinoma

Figure 1

Representative photomicrographs of HIPK2 expression interpreted as 0 (a), 1+ (b), 2+ (c), and 3+ (d) in immunohistochemistry (arrow, positive nuclear staining). (e) HIPK2 mRNA expression level in tonsillar squamous cell carcinoma is significantly increased compared to that of normal tonsil.
