NR4A1 and invasive ductal breast carcinoma: Fig 3D shows the similarity in GPCR expression for Grades 1 to 3 (G1 to G3) PDAC tumors. Median expression of GPCRs was also similar in PDAC tumors with different pathological T (Fig 3E). Similarly, Stage 1 and Stage 3A BRCA infiltrating ductal carcinoma (IDC) Hormone Receptor–positive (HR+) tumors have comparable GPCR expression and DE (Fig 7D).
