Correlation of AhR expression with clinical characteristics of breast cancers. The semi-quantitative analysis revealed that for each target protein examined, there was no significant Difference in staining intensity between grades, TNM, ER, PR, C-erbB2, Ki-67, AR, EGFR, Molecular subtype, except for P53 and histological types
