Methods: We disrupted the PR gene (PGR) in ERα-positive/PR-positive T-47D cells using the CRISPR/Cas9 to control T-47D cells. We analyzed the gene expression profiles of PR-low and control T-47D cells in the absence of hormone 47D cells. More than 6000 genes were DE in control T-47D cells upon stimulation with P4 or P4 plus E2.
