By using siRNA targeting NRIP1 (siNRIP1), we suppressed NRIP1 expression in 5 breast cancer cell lines (MCF7, T47D, HCC1806, MDA-MB-231 and HCC1954), which includes all three molecular subtypes of breast cancer, and used MCF10A as a control. This evidence concerns the gene NRIP1 and breast carcinoma.
