AhR is expressed in normal breast and in a range of human breast tumors. Tissues were derived from 48 patients, and RNA was isolated and provided as first-strand cDNAs on the TissueScan Breast Tissue pPCR Array Panel I (Origene Technologies; BCRT-01). qPCR was used to analyze hAhR expression in the 48 independent patient-derived tissue samples. Data were normalized to β-actin, and samples in each tissue type (Normal or stage 0–III) were averaged. Graphic data are depicted as relative fold expression over the average of values obtained using normal breast samples (set at 1). Error bars represent sd among independent samples of each tissue type. The distribution of the 48 patient samples represented as a function of breast tissue tumor grade was: normal breast: two samples; stage 0: five samples; stage I: 10 samples; stage II, 20 samples; stage III, 11 samples.
