ERX-11+palbociclib treatment alters ER interactions with coregulators. a–d MCF-7 cells were treated with E2 (10−8 M) in the presence or absence of ERX-11 (10 μM), palbociclib (0.25 μM), or ERX-11+palbociclib for 2 h. Cell lysates from treated cells were subjected to immunoprecipitation with ERα antibody. The immunoprecipitates were analyzed by mass spectrometry
