Nucleoporins as drug targets for anti-proliferative therapeutics
View Patent ↗Disclosed herein are methods of inhibiting nuclear pore complex assembly and inducing nuclear pore complex disassembly. Methods to screen for agents that inhibit nuclear pore assembly or induce nuclear pore complex disassembly are also disclosed.
1. A method of treating a proliferative disease or disorder in an individual in need thereof, comprising:
administering to the individual a therapeutically effective amount of an agent that inhibits nuclear pore complex assembly or induces nuclear pore complex disassembly, wherein the nuclear pore complex assembly is not inhibited in non-dividing cells or the nuclear pore complex disassembly is not induced in the non-dividing cells, wherein the proliferative disease or disorder is cancer, wherein the cancer has a mutation in Ras gene, and wherein the agent is a small interfering RNA (siRNA) or short hairpin RNA (shRNA) that targets Nup160 of the nuclear pore complex.
2. The method of claim 1 , wherein the agent inhibits expression of a component of the nuclear pore complex.
3. The method of claim 1 , wherein the agent promotes degradation of a component of the nuclear pore complex.
4. The method of claim 1 , further comprising administering an additional therapeutic agent.
5. The method of claim 1 , wherein the cancer is melanoma cancer.
6. The method of claim 1 , wherein the mutation is a G12D mutation.
7. The method of claim 1 , wherein the administering to the individual the therapeutically effective amount of the agent comprises contacting a cell having a number of nuclear pore complexes with the agent wherein the agent reduces the number of the nuclear pore complexes in the cell.
8. The method of claim 1 , wherein the cancer is colorectal cancer.
