SLC10A6 and invasive ductal breast carcinoma: Whereas SOAT expression was relatively low in the ductal epithelium of normal breast tissue (Figure 2A), strong SOAT immunoreactivity was detected in ductal hyperplasia (Figure 2B), intraductal papilloma (Figure 2C), atypical ductal hyperplasia (Figure 2D), intraductal carcinoma (Figure 2E), and invasive ductal carcinoma (Figure 2F).
