Analysis of SNAT1 expression in human breast cancers and adjacent normal specimens. (A) Normal (nonneoplastic) breast epithelium with negative expression of SNAT1; (B) Negative SNAT1 expression in breast cancer specimens; (C) Representative SNAT1 positive expression in breast cancer specimens; (D) High level of SNAT1 expression in tumor cells (T) and low SNAT1 expression in nonneoplastic breast epithelium (N); A1, B1, C1, D1, D2: Enlargement of tissues in the frames from A, B, C, D, respectively. Original magnification of A, B, C, D: 100×; Original magnification of A1, B1, C1, D1-2: 400×.
