WT and mutant PR-A and PR-B isoforms are expressed at equivalent levels in stably transfected hTERT-HM cells. A, hTERT immortalized human myometrial cells were stably transformed using recombinant lentiviruses expressing PR-BWT, PR-BmDBD, PR-AWT, and PR-AmDBD conjugated to GFP at their N-terminal ends. PR-B DBD and PR-A DBD mutants (PRmDBD) contained a triple mutation (G584E/S585G/V589A) within the P-box region of the DBD. B, immunoblotting of total cell lysates revealed that levels of PR expression in the four stably transfected cell lines were equivalent. LBD, ligand-binding domain.
