We further analyzed the expression pattern of Star-PAP in Oncomine, a publicly accessible cancer informatics database, with the Neve cell line data set that includes the transcriptional profiles of 51 breast cell lines.12, 13 Among this collection of cell lines (n=51), the breast cancer cell lines (n=48) also exhibited lower Star-PAP expression levels than the immortalized breast epithelial cell lines (n=3; HBL-100, MCF10A, MCF12A) (Figure 1d). Here, STAR is linked to breast carcinoma.
