Experimental Protocol


The study contains 3 different cell lines (PR-null, PRB-wildtype, PRB-K388R) tested with 8 different treatments in triplicate (8 x 3 x 3 = 72 individual samples). We also included 12 previously published samples (GSE34148) with the same treatments, which increased our total number of samples to 84. From parental T47D-Y (PR-null) human breast cancer cell lines, we created stable clones expressing either (1) an empty vector (pIRESneo3) or (2) the wild type progesterone receptor isoform B (pIRESneo3-PR-B), or (3) pIRESneo3-PR-B-K388R. These three cell lines were co-treated with either (1) vehicle control (ethanol) or (2) progesterone/R5020 10e-8 M, (3) RU486 10e-7 M, (4) onapristone 10e-7 M, (5) aglepristone 10e-7 M, (6) progesterone plus RU486, (7) progesterone plus onapristone, or (8) progesterone plus aglepristone. Treatments were for 6 hours before total RNA harvest. Standard Illumina HT-12v4 chip was used for gene expression analysis.
