We searched the Oncomine database for AGTR1 expression in breast cancer in lymph node-positive and lymph node-negative breast cancer patients and found that high expression of AGTR1 mRNA also occurred in lymph node-positive patients compared with lymph node-negative patients [0.12 vs. –0.88 (log2 median-centered intensity)] (Figure 1C). Here, AGTR1 is linked to breast cancer.
