To analyze the expression of SIPA1 in different cancer cell lines, we determined the mRNA levels of the Sipa1 by quantitative real time-PCR (qRT-PCR) in four breast cancer cell lines (MDA-MB-231, BT549, SK-BR-3 and MCF7), three colon cancer cell lines (HCT116, SW480 and Caco2), two prostate cancer cell lines (PC3 and LNCaP) and an endometrial adenocarcinoma cell line (HEC1A). Here, SIPA1 is linked to endometrium adenocarcinoma.
