LNCaP and C4-2 Cells were treated with inhibitors for ER (ICI), ESR1 (MPP), ESR2 (PHTPP), AR (Bicalutamide), and GPR30 (G15) for 72 h in the presence and absence of BPA and its analogues as indicated. Cells were fixed and scored for number of cells with centrosome numbers ≥3. Significance was calculated relative to no inhibitor group. *p<0.05 **p<0.005 ***p<0.001.
