Bromocriptine and cabergoline induce cell death in prolactinoma cells via the ERK/EGR1 and AKT/mTOR pathway respectively

a–d Cell survival was determined by the CCK8 assay. MMQ and GH3 cells were treated with CAB and BRC at concentrations of 0, 25, 50, and 100？μM, respectively, for 24, 48, and 72？h. e GH3 and MMQ cells were treated with CAB or BRC at a concentration of 50？μM for 48？h, and cell viability was tested with the CCK8 ki
