Dept. of Pathology AbstractIn the present study, we examined the effects of calmodulin (CaM) antagonist N-(6-aminohexyl)-5-chloro-1-naphthalenesulfonamide hydrochloride (W-7) on androgen-sensitive, LNCaP, and androgen-independent, PC-3, prostate cancer cell lines. Proliferation of LNCaP cells was six times more sensitive to the inhibitory effect of W-7 than were PC-3 cells. To explore the molecular mechanism for this inhibition, the relative amounts of CaM in LNCaP and PC-3 cells were analysed. Western blot analysis revealed two and three fold greater amounts of CaM in the nuclear and cytoplasmic fractions, respectively, of LNCaP cells than in those of PC-3 cells. These studies provide indirect evidence for the biological interaction between androgen receptor (AR) and CaM and suggest the potential usefulness of CaM antagonists in blocking AR activity in prostate cancer. It also suggested the possible involvement of CaM in regulating proliferation of prostate cancer cells. This is a preliminary report and further understanding of the molecular mechanism of Ca2+/ CaM action in prostate cancer is required. Repository Staff Only: item control page
