Increasing parkin activity by administering a deubiquitinating enzyme inhibitor
Provided herein are methods of promoting parkin activity in a subject, comprising: selecting a subject with a disorder associated with decreased Parkin activity; and administering to the subject an effective amount of a composition that increases parkin activity, wherein the composition is an inhibitor of a deubiquitinating enzyme.
1. A method of promoting parkin activity in a subject that has a neurodegenerative disease of the central nervous system, a myodegenerative disease or a prion disease, comprising:
a) selecting a subject with a disorder associated with decreased parkin activity, wherein the disorder is a neurodegenerative disease of the central nervous system, a myodegenerative disease or a prion disease, wherein the neurodegenerative disease is selected from the group consisting of Amyotrophic Lateral Sclerosis, Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, and Mild Cognitive Impairment, an α-Synucleinopathy and a Tauopathy; and
b) administering to the subject an effective amount of a composition that increases parkin activity, wherein the composition is an inhibitor of a deubiquitinating enzyme.
2. The method of claim 1 , wherein the deubiquitinating enzyme is USP-10 or USP-13.
3. The method of claim 1 , wherein the composition increases parkin activity by promoting the interaction between parkin and beclin-1.
4. The method of claim 1 , wherein the composition inhibits deubiquitination of parkin.
5. A method of treating a neurodegenerative disease, a myodegenerative disease or prion disease in a subject, comprising:
a) selecting a subject with a neurodegenerative disease of the central nervous system, a myodegenerative disease, or a prion disease, wherein the neurodegenerative disease is selected from the group consisting of Amyotrophic Lateral Sclerosis, Alzheimer's Disease, Parkinson's Disease, Huntington's Disease, and Mild Cognitive Impairment, an α-Synucleinopathy and a Tauopathy; and
b) administering to the subject an effective amount of a composition that increases parkin activity, wherein the composition is an inhibitor of a deubiquitinating enzyme.
6. The method of claim 5 , wherein the deubiquitinating enzyme is USP-10 or USP-13.
7. The method of claim 5 , wherein the composition promotes the interaction between parkin and beclin-1.
8. The method of claim 5 , wherein the composition inhibits deubiquitination of parkin.
