As grading for DCIS and IDC is different, we examined CPB1 expression in low vs. high-grade DCIS and IDC separately and found a similar pattern for DCIS only (p-value = 0.33) and IDC only (p-value = 0.06), although these associations were not significant (Figure S2A,B). The gene discussed is CPB1; the disease is ductal breast carcinoma in situ.
