PUM 1 protein as target for virus inhibition
View Patent ↗Disclosed is a method for prophylaxis or treatment of infection of a virus, or for modulating innate immunity, in a subject comprising administering to the subject a therapeutically effective amount of a PUM1 inhibitor. A pharmaceutical composition comprising the PUM1 inhibitor is also disclosed.
1. A method for treatment of infection of a virus in a subject, comprising administering to the subject a therapeutically effective amount of a PUM1 inhibitor, wherein the PUM1 inhibitor is an antisense oligomer that targets a nucleic acid molecule encoding PUM1 to block the synthesis of PUM1 wherein the virus is Hepres Simplex Virus type 1 or type 2.
2. The method of claim 1 , wherein the virus is an interferon sensitive virus.
3. The method of claim 1 , wherein the antisense oligomer is delivered by a vesicle.
4. The method of claim 1 , wherein the nucleic acid molecule encoding PUM1 is selected from DNA encoding PUM1, RNA transcribed from the DNA, and cDNA derived from such RNA.
5. The method of claim 1 , wherein the antisense oligomer is selected from a DNA oligonucleotide, an RNA oligonucleotide, and a chimeric oligonucleotide.
6. The method of claim 5 , wherein the antisense oligomer is selected from dsRNA, siRNA, and shRNA.
7. The method of claim 3 , wherein the vesicle is an exosome.
8. The method of claim 1 , wherein the administration of the PUM1 inhibitor induces upregulated expressions of interferon and interferon stimulated genes.
9. The method of claim 8 , wherein the interferon stimulated genes is selected from LGP2, CXCL10, IL6, PKR, RIG-I, MADS, SP100, IFIT1, PML and STING.
10. The method of claim 1 , wherein the subject is a mammal.
11. The method of claim 10 , wherein the mammal is a human being.
12. The method of claim 1 , wherein the antisense oligomer comprises the sequence of 5′-gcugcuuacuaugaccaaatt-3′ (SEQ ID NO: 1).
13. The method of claim 1 , wherein the virus is an interferon β sensitive virus.
