Figure 4. Expression of dopamine receptor-1 (D1R) in breast carcinomas and patient survival. A: Distribution of immunoreactive D1R in tissue microarrays containing 751 breast carcinomas and 30 normal breast samples. Data are shown as the percent of total tumor number. All 30 normal tissue samples were also D1R-negative; B: positive D1R expression in breast tumors is associated with shorter patient survival, as determined by Kaplan-Meier analysis of 508 tumors.
