A. Inhibition of PC-3 cell proliferation was enhanced by genistein as measured by MTT assay. G indicates treatment with 30 μM of genistein (*: P < 0.05 compared with SB715992 treatment alone, n = 5). B. Induction of apoptosis in PC-3 cells was enhanced by genistein. G indicates treatment with 30 μM of genistein. (*: P < 0.05 compared with SB715992 treatment alone, n = 3.). C. Inhibition of PC-3 cell proliferation was enhanced by pre-treatment with genistein. G indicates pre-treatment with 30 μM of genistein. (*: P < 0.05 compared with SB715992 treatment alone. n = 8).
