Method and composition for diagnosis or treatment of aggressive prostate cancer
Methods, pharmaceutical formulations and medicaments for treating prostate cancer or preventing the progression of a nonaggressive form of prostate cancer to an aggressive form, in a mammal, include a therapeutically effective amount of one or more active agents that reduce the expression or biological activity of both Forkhead box protein M1 (FOXM1) and Centromere protein F (CENPF) or biologically active fragments thereof or biologically active fragments thereof selected from the group consisting of an isolated shRNA, siRNA, antisense RNA, antisense DNA, Chimeric Antisense DNA/RNA, microRNA, and ribozymes that are sufficiently complementary to either a gene or an mRNA encoding either FOXM1 or CENPF proteins. A method is also presented for discovering synergistic master regulators of other phenotype transitions, wherein the master regulators are conserved among different species.
1. A method for treating prostate cancer or preventing the progression of a nonaggressive form of prostate cancer to an aggressive form, in a mammal, the method comprising: administering to the mammal a therapeutically effective amount of one or more active agents that reduce the expression or biological activity of both Forkhead box protein M1 (FOXM1) and Centromere protein F (CENPF) or biologically active fragments thereof, wherein the active agent is selected from the group consisting of an isolated short hairpin RNA (shRNA), short interfering RNA (siRNA), antisense RNA, antisense DNA, Chimeric Antisense DNA/RNA, microRNA, and ribozymes that are sufficiently complementary to either a gene or an mRNA encoding FOXM1 or CENPF.
2. The method of claim 1 , wherein the prostate cancer is aggressive prostate cancer.
3. The method of claim 1 , wherein the active agent is administered orally.
4. The method of claim 1 , wherein the active agent is administered locally to a prostate gland or prostate tumor.
5. The method of claim 1 , wherein the active agent is a nucleic acid comprising a sequence selected from the group consisting of SEQ ID NO: 1, SEQ ID NO: 2; SEQ ID NO: 3; and SEQ ID NO: 4.
