Figure 1

Biomarker detection in breast cancer tissue. Androgen receptor (AR), estrogen receptor (ER), and progesterone receptor (PgR) expression determined by immunohistochemistry (10X magnification) in primary tumor and metastasis from one patient, with relative AR/ER, AR/PgR, ER/PgR ratios calculated.
