Correlation of membrane TAAR1 expression, with grading of serous carcinoma, showed that TAAR1 is expressed significantly higher in low-grade serous carcinoma (median IRS of 4; n = 22) compared to high-grade serous carcinoma (median IRS of 3; n = 71) (p = 0.028) (Figure 3). This evidence concerns the gene TAAR1 and serous adenocarcinoma.
