MaPR172H/− and MaPR245W/− mammary tumor-derived cell lines were transfected with either Nr5a2 siRNAs (si-1, si-2, si-3, and si-4) or universal nontargeting control siRNA (J-047044-09-0010, J-047044-10-0010, J-047044-11-0010, J-047044-12-0010, and D-001810-10-20, respectively, Horizon Discovery). Here, NR5A2 is linked to breast cancer.
