Figure 4From: Hornerin, an S100 family protein, is functional in breast cells and aberrantly expressed in breast cancer Correlation of hornerin expression with breast cancer subtype and TNM staging. (A) Representative images of breast cancer biopsies that were subjected to immunohistochemical analysis using a hornerin-specific antibody or corresponding negative control (219 individual patient samples analyzed). Yellow bar = 200 μM. Hornerin expression in correlation with (B) breast cancer subtype IDC = invasive ductal carcinoma. ILC = invasive lobular carcinoma, (C) tumor grade, and (D) lymph node metastasis. Data represent mean relative intensity +/− SD. *P < 0.05.Back to article page
